Side by Side Comparison of: Honeywell

I had some initial troubles installing the unit but after find the actual power feed down on the furnace board and tapping into it, the unit powered on no problem. Setup was easy and it's proven quite reliable. Managing the HVAC from my smart phone is nice. I rarely use the actual unit but it looks a lot better than the ugly LCD unit I had on there.

I wish I could set the Heat/Cold temperature ranges to a tighter difference. Currently it forces a 3* separation and in my house, that can make a difference in comfort. However, for the cost, I recommend this vs the competitors.

Also, honewell is good and notifying you of planned maintenance if the app link to their servers will be down. Other than that, I've had zero connectivity issues.

Great Thermostat! I read a lot of the reviews prior to purchasing and after receiving mine and installing it myself I dont see what the 3 star and below reviews are about. the unit was not difficult to install, the back-plate / mounting plate seem to be fine and I had no issues with the wiring. The only thing I can figure is that the other people with the lower reviews probably had no business installing a thermostat themselves or probably anything else for that matter. It does take some dexterity to wire the unit. The wires and slots for the wires are small. But other than that..Read the instruction, watch a video or two that Honeywell has or on YouTube and put it on the wall. No big deal. I like the thermostat I purchased and it does appear to work much better then the factory Carrier thermostat I replaced it with. The HVAC heat pump unit actually cycles properly now and the temperature in the house seems to be much more consistent. Two Thumbs Up!

I'm giving a head-to-head review. I've had both a Nest 3rd Generation thermostat and this Honeywell touchscreen thermostat. I like both a lot, actually. It depends on what you're looking for in terms of deciding which is better for you specifically.

I love the simplicity of the Honeywell's touchscreen. And I like that it tells you the outside temps and humidity, the date, and time all on the home-screen, all at once. Nests have much less info on the screen and you need to turn the dial and find everything, like weather, etc. On the Honeywell, to navigate to settings and schedules, there are touchscreen tabs at the top of the screen. Pretty intuitive.

Wiring:
The Honeywell absolutely requires a "C" wire to work. If you don't have one, you will need to run one for the Honeywell for it to work. I originally did not have one, but I had one added for $100 by an electrician. If you don't want to go through the expense or hassle, you may want to go for the Nest instead, because while the system works best with a C wire, it can work without one. But it depends on how much power it can pull from the other wires. Not having a C wire can make its Wi-Fi connectivity spotty/intermittent. And that means sometimes you can't interact with it via the mobile App and delays in it knowing what the external weather is.

Apps:
Nest has its merits, for sure, like their App that gives a lot of insights as to how you're doing with efficiency (like showing that for the past week, Monday, the heater only ran for 15 minutes; and Tuesday, it didn't come on at all... that kind of thing). I will say, however, Honeywell and Nest keep improving their Apps continuously, so as soon as I comment on App features, they change and have new functions... so that's a positive for both products. Who can be upset with constant improvements?

Aesthetics:
Both the Honeywell and Nest are very slick/modern looking. With this Honeywell, having the ability to choose your screen color to work with your décor or style is something that's pretty neat. Or you can change it up when you're bored. The Nest, however, does not have a function to change its color. It is always black. On the other hand, the Nest itself with its circular face is just pretty cool looking on its own. I'll leave you to decide what is more pleasing, as it's a matter of opinion.

Some notes about programming your schedule:
Nests, are all about "learning" about you. So, in default/factory setting mode they are set in "auto" schedule program mode, which means you go about your daily routines and "train" it, so it learns your preferred home temps and schedule. If you're letting it "learn you", it goes something like this... You to wake up, change the temp, leave the house and adjust the temp before doing so, come home and ... You get where I'm going. Finally, after a few days of that, it pretty much understands your patterns (unless you're really unpredictable/erratic). That learning feature can be awesome for some, since some folks want to let it do the work. But some people are more control freaks (like myself) and want to tell it what temps at what times to come on and off from the get-go. So, if you find the learning feature takes too long to learn your schedule, simply read the directions and turn off the auto learn function, and then program your schedule to however you want. The Honeywell does not learn and has you set your desired temps and schedule from the first moment you install it by default. But it gives you quick-set recommendations, which make setting up the schedule super-fast.

Bottom line:
Both are absolutely great thermostats. I love them both for different reasons. Maybe the biggest difference for some would be the "C" wire requirement for Honeywell (if you don't have a C wire in your wall already and if you don't want to have to have that wire added).

I always read reviews before purchasing and find some quite helpful, so I hope you find this review helpful!

This thing is glorious. It has a bright, easily readable screen that is crisp and clear, and it looks nice on my wall. Installation was (mostly) a snap, and took less than 20 minutes to get it from Amazon box to on my wall.

I bought this thermostat for four reasons: 1) It seemed to have more functionality than the NEST, 2) It was about $100 less than the nest, 3) it works with Wink, and 4) I can use set it up for monitoring by my electric company (CPS in SATX), and I'll get ~$120 in rebates, which lowered the cost to purchase to ~$40!

A few nuggets of advice that you might find handy: check what sort of heat source you have in your house, whether it's forced air or a heat pump. If you wired it correctly (after obsessively checking five or fifteen times) and it's still blowing hot air when your AC is nominally on, then you have that particular setting configured incorrectly. Go back and change "forced air" to "heat pump," or vice versa. Also, when you first turn on the unit, there is a five-minute lockdown to prevent the system from blowing itself out. Just wait it out, and go from there. (These things are printed in the instruction manual, but... yeah, I stopped reading once I saw where the wires were supposed to go, so I missed this. Be smarter than I was, and read at least the quick-start guide all the way through.)

I purchased this thermostat for my father. He isn't a big tech fan so I was worried he wouldn't be able to use it. He loves it! It is extremely easy for him to use. He even purchased a second one for the upstairs unit.
Normally I would install something like this myself and be able to give details, but we already had a professional over installing a new air conditioning/heating unit and he offered to install it for no extra charge. I spied on the installation a little and it just looked like a few wires.
Once it has power, there is an easy to follow guide to set all your defaults, wifi and even colors.
Honeywell has an app so you can control this thermostat from your phone when you are away from your home or if you just don't want to get out of bed at night to adjust it. Setting that up was pretty easy. You create an account on Honeywell's website. It will ask you for your thermostats MAC address which you can get right from the thermostat screen. Once done, download the app to your phone (iPhone in this case), sign in and all your controls and current temperature are right there.
Overall, a great product that will help you reduce energy costs.

Having 2 independent conventional A/C systems I was pretty apprehensive. I replaced 2 existing thermostats provided by Comcast Home Security... a service I grew to dislike. I did not have a problem setting up both thermostats on the Honeywell web site (in preparation for installing new thermostats). I suggest doing this before swapping out the old thermostats. Double check that you have entered the MAC ID and CRC data EXACTLY as provided in the package of info that came with the thermostat. Again... it worked great for me to get this setup done before actually swapping the thermostats. I think this can be done using the cell phone Ap but. I did this on my PC... I did this step on my big screen PC. There were no issues wiring the new thermostats as wiring matched the existing thermostats. With new thermostats installed it was very easy to log them into my router and finish the device connection (aka registration) on the Honeywell web-site. It worked perfectly first time. Lastly... There are a ton of options available for tweaking your air conditioning needs to your comfort level. There is also an option for dimming the brightness of the display. Here is how: select "menu" "preferences" "backlight" and raise or lower the brightness. I rarely write a revue... but I was exceptionally pleased with this product. Don't forget to install the Honeywell thermostat AP on your cell phone

Well this thing is amazing. If you don't have a c wire or the ability to add the c wire then purchase the adapter. I had the ability to add the c wire. The auto mode is now hidden deep in the menu. Just google search and the instructions to active auto switching between heat and A/C. Don't know why this was buried that is my favorite feature as in the Chicago area switching between heat and air is common in late winter early spring and late fall early winter. My old thermostat did that but recently failed to do so (broke). I was bummed but have to say not anymore. Can access the thermostat from anywhere with the app on smartphone or by logging in on computer. Works with Alexa and love the interface. Also has a smart learn feature that learns how long it takes to get to desired temperature in the morning so when you wake it is that temp. That is working and is very nice. Great buy, awesome unit!

Really nice, easy to program, the screen is very easy to read. The remote access via WiFi and app is very fast and dependable. In my set up is 2 heat and 1 cool with a heat pump/AC. The two stage heat works very well but you cannot program how you want the AUX or emergency heat to work. The heat pump is 1st stage and the 2nd stage is electric heating elements. A email from Honeywell explained it since I could not find it in any documentation. You can set it for "emergency" heat only and this locks out the heat pump compressor so only the electric elements are being used. The installation instructions were very good for both the wiring and programming. It does have a "Smart Response Technology" option to determine how long it take to get the temperature to the set temp. It also has a "Utility Schedule Options" feature for easier programming for parts of the country that have different rates for electric power at different times of the day.From Honeywell:...When you leave the system in heat mode it runs the heat pump for heating and if the heat pump is not able to satisfy the heating requirement of the house, the thermostat turns on the backup/second stage along with the heat pump to assist in heating the location.At this time the thermostat will show “Auxiliary Heat On’ on the display. The thermostat uses a pre-programmed algorithm to determine when the second stage should turn on....

Just installed today and it went very well. The product needs the "C" wire but that was a simple and easy install as the existing wire had two unused leads. I just connected one of the extra wires to the Com terminal at the furnace and then connected the other end to the C terminal on the thermostat. After that, the set up was very simple. Just follow the prompts. Then download the app to your phone and your computer and you're in control. A plus for me is this product does work with Alexa (Echo). I had read that it did not but it does. This version also says it has a five year warranty as it is a "Pro Install" product, I guess. Some answers to questions said this model did not work with Alexa however, there is a skill and app that allows it to work very well with Alexa. That is a small thing, really, but fun. I've only had it a short while but I've used my phone app to change the settings as well as the computer and it works flawlessly so far. In my area, this model does not qualify for the energy rebate from the electric utility (ComEd) although the Honeywell Lyric model does. However, net price was only $10.00 more than Nest or Ecobee and I have had good luck with Honeywell products.

Amazing thermostat. Works flawlessly. The app loads instantly, is very responsive. The programming is straightforward and easy to double check that things have been set to your liking. It never does anything I don't want it to (unlike my old analog that reset itself randomly) likely thanks to a lack of batteries over hard wiring with C wire. I can only assume the battery contacts can loosen with repeated use, and can occasionally power off and reset itself.A few things about the C wire:The install was a bit tricky for my situation, because I had to pull out additional wire from the wall, and the original installer left almost no slack. The C wire was cut completely back to the point of not being visible upon initial inspection.I had to pull it out 6 inches and cut all wires again, and restrip. The same was true for the wires on the air handler itself, the C wire was cut, and I had to cut the whole thing and restrip/reattach each wire. I had to do this for both air handlers in my house too (two separate units).Once the the wire was in place, it took only a couple minutes to attach two anchors to the wall and fasten / level the mounting plate. After that, the unit slipped on with no trouble. Once I flipped the breaker back on it fired up instantly, I went through the setup, and it took about 20 minutes to update so it was accessible. The programming was straight forward, also allowing you to use between 1-4 timers in a day. I appreciate the hold until function, as I can never worry about remembering to turn it back onto programming. I can crank the heat right as I wake up, and have it automatically turn back to regular programming an hour later as I'm leaving the house.A few things about the unit itself:The touch screen has VERY crisp and bright color, much like my iPhone. The unit itself is very small and sleek, maybe 1.5x the size of my iPhone 6. The unit has a bright white backing, with clear plastic over that very similar to the old white Macbooks. It has pages of preset colors, as well as completely adjustable background colors which I thought was silly, but have grown to like. I realized that it's one more thing to match, and one more reason it looks so aesthetically pleasing to me. Change it to your favorite color, to match the wall, or to match the season! I thought the touch screen might be annoying to use, yet it's quite the opposite. I never find myself mashing the screen to get a button pressed. Beyond that, it has a very simplified menu.Overall I love this thing, not one problem. It's exactly what I was looking for in a WiFi thermometer and has more features than I thought I would use. I would highly recommend them to a friend.

Installed two of these Honeywell TH9320WF5003 WiFi 9000 thermostats in our Community Clubhouse building where previously the thermostats were not managed and possibly ran unsupervised 24x7 for years even when the building was unoccupied.Once the common 24V wire was identified, the rest of the installation was a breeze. Took about 5 minutes each to install and configure.Configuration on the WiFi network was simple and the Honeywell Connect web application very intuitive.So far, accuracy and stability of the set temperature has been impressive. I found that it did not work well in "Automatic" mode when the outside temperature was about 68 degrees and we wanted inside cooling to about 72 degrees, the thermostat called for "heat" instead.My solution was to operate the thermostats in manual cooling mode instead.The Honeywell Connect Android app works well and closely resembles the web-based version of the app.The thermostat controls may be customized to send a myriad of notifications to user's email if desired. Remote management via Honeywell Connect may be easily shared with designated individuals who need control over the settings.In addition, I mounted the Honeywell CG511A1000 Medium Thermostat Guards over the thermostats and while the guards are not intended to be 100% tamper proof, they work well in my situation. Photo shows the thermostats with Honeywell Good Plate ( covering the old footprint).

I had an old Honeywell thermostat on this house I purchased last year. It was programmable, but was a pain in the neck to set up. So after I got my Amazon Alexa, I checked out the Amazon website for a reasonable priced thermostat that would work with an Echo. This Honeywell caught my eye, so I read the reviews and decided on this one. Since someone mentioned in their review that the warranty would be compromised if it wasn't installed professionally, I paid my H/C guy the $60 that he wanted to install this when he came for my yearly system checkup.It is a really nice thermostat. It gives your local weather conditions, temps, humidity ( inside and out) and time. You can change the color to suit your taste. Not only does it work with Alexa--it also works via your downloaded phone app. Yes, if you unexpectedly discover that you'll be gone most of the day, you can change the settings through your phone app. Convenient!The only reason I dock a star in the rating is because for some reason, in the middle of the night, the screen gets light enough to act as a nightlite. I don't know why, but it is a little irritating. Other than that, operation has been flawless for over 6 months now.

Looks good, easy install even if you do not have the proper "C" wire but the "smart" recovery mode never really learned to time the furnace to reach the scheduled temperature. In fairness, our weather and the resulting ambient temperature has been very volatile this winter. But furnace would frequently fire to early, sometimes by over an hour, and the temperature would exceed the scheduled temperature both in time and heat by a considerable margin. We finally resorted to turning off the "smart response mode" and just use the thermostat the old fashion way. At least we have wifi access (which we will probably never use) and it displays the outdoor temperature with an additional component. I was also disappointed that it does not integrate with our second furnace system using Honeywell's zoned wifi system other than through the Honeywell server portal. I had anticipated using our Honeywell remote thermostat to control and monitor both furnaces and their zones. In summary, the stat could be smarter and more integrated with the current Honeywell products.

This was a great buy. It cost 200+ in the store so the price is great. I picked this because I wanted wifi, app enabled thermostat. I did NOT want the stupid AI Nest crap. no thanks. You can get cheaper wifi but I paid extra for the nicer looking design and the weather integration. It was very simple to install and connect to my router. I reduced it 1 star for the following 3 reasons.1. The tabs on the wire connectors were flimsy and 1 broke off exposing one of my wires during install. In reading the manual afterwards it does specify to ensure your wires are perfectly straight before inserting them so there is a warning. Be sure to follow this and you will avoid my mistake. It did not impact operation at all just annoying.2. When it disconnected from my router 1 time in 3 months of owing it, it did not recover gracefully. I had to delete the connection and make a new router connection.3. there is a slight delay in the touch screen responsiveness. Enough to be annoying but not a gam changer since I use my phone mostly.Overall its a great product and I will be buying a second one for my downstairs. I wanted to test this one before buying both. I would reccomend this over the more $$ Nest anyday.

Love the T-stat, it connects easily, and I didn't need to do any fancy port forwarding etc for my router to get it to work. It controls it reliably, or at least it has for the past 2 days.I took off a star for 2 issues with installation.First, the snap-in connectors I'm not a fan of, personally. Being on both sides (a left and a right) inserting the wires definitely needs some needle nose pliers. I prefer the screw in terminals. Having to relocation this thermostat I fear those small snap in connectors will wear out. Hopefully any replacements would be cheap (if ever needed) since it's just a back plate. Also, be sure to cut back your wires if your t-stat wire doesn't have room to move into the wall. Mine was stapled tight on the other side of the drywall, and if you have the smallest amount of excess wire, the tstat will not snap on. I had to re-do the installation after cutting an inch off of each wire.The 2nd issue I have with the installation is that they don't describe the wires very well, just the colors. One connection is O/B-W, and if you have an orange, a white and a blue, this was confusing. I wish they would say "the O/B/W is for the reversing valve". Installers will know this by heart, but going from a Bryant tstat to this, I wanted to make sure I got it right, and I had to do my own research. For those going from Bryant, my experience was that O/Orange goes to O/B-W and the W/White goes to W2 (emergency heat).I would buy it again, and plan on buying more for a vacation property I have.FWIW, While on vacation this week, I was able to remotely program it to stay at 80 degrees cool until 3am and then go down to 75 until 6am, then back to 80. I did this rather than the vacation mode because it allows my system to "bank" the cooler air when it's cooler outside and run at peak efficiency, hopefully reducing the amount of run time during the hottest part of the day. Since I can put the system back to 74 when driving home, the "vacation mode" doesn't appeal to me.Note to Honeywell, I wish the vacation mode supported that economy method I used (bumping down at 3am for 2 hours).

The bottom line: the thermostat works perfectly well, but installation can be tricky, at least for an older Water Furnace geo-thermal system. Water Furnace has an internet connected system for its newer units, but nothing that can run an older unit. I had read of horror stories with trying to use Nest on geo-thermal systems and this thermostat was recommended by a geo-thermal installer/consultant. "You can do the wiring yourself," he said. Wrong: one look at the way the Water Furnace displays its wiring scheme was enough to convince me to hire a professional.And here's the lesson: I hired the same company that had installed the geo-thermal system for the previous owner 13 years earlier (the consultant was based much further away). Truthfully, I was uneasy when I asked the technicians who showed up told me neither had installed this thermostat before. About an hour after they finished and departed, I realized I could not lower the settings -- or even turn off the thermostats (two zones). Nor did the company answer its phone (1pm). A recording provided an "emergency number" -- but its mail box was full. I called Honeywell customer service and a 30-minute on-hold wait later, got connected to a rep in, I believe, India. That's OK. Except the phone line went dead in middle of the call. All I had learned to that point was that if one removes the digital face of the thermostat (like some old car stereo units) it shuts off. To skip ahead several days, I got the consultant to come down and reinstall the wiring and settings...all seemed to be working fine, except...Lesson 2: Be careful with the digital face plate. This thermostat has a base that is screwed to the wall. You attach the various wires to terminals on this base plate. Then the digital face just "snaps" on and the thermostat comes to life. YOU MUST BE CAREFUL ON HOW THIS FACE 'SITS' ON THE BASE PLATE. There are perhaps two dozen tiny pins that must be carefully aligned and pressed into place. Unfortunately, one of the pins got slightly bent and didn't connect properly. The thermostat worked, except the supplementary propane boiler would not kick in (all geo-thermal systems have, or should have, a "supplementary" system). Yet another call (and fee) to a third company fixed this problem.Now that the installation is correct, I find the thermostat works flawlessly. I can control and program it from the free app. The daily and weekly programming is the easiest I've encountered. The Internet connection has worked more or less flawlessly.I'm rating this four stars because I believe the installation headaches, while partially self-inflicted, shows just how complicated it can be to wire up correctly -- at least for an older Water Furnace geothermal system.

Unlike the older thermostats which are battery powered, the Honeywell RTH9580WF WiFi 9000 needs the "C" wire to operate. The "C" wire provides the needed power. For full functionality the wire between your HVAC unit and the thermostat needs to have 5 wires (C, R, G, Y and W) That is for a conventional gas system for heating using forced air and AC. For other systems, such as heat pump, check the manual which can be downloaded from the product page on Amazon or from Honeywell.If your wiring does not have 5 wires and you do not want to go thru the expense of pulling a new thermostat run, you do have a few choices:1. Reassign one of the existing wires to be used as the "C" wire. This will lose some of the fan control options.2. You can use the Venstar ACC0410 Add-A-Wire for all 24VAC Thermostats.3. You can use the Honeywell THP9045A1023 WireSaver Module for Prestige Thermostats.The third option seems to be the best. The cost of the Honeywell WireSaver Module is about half of the Venstar Add-A-Wire and it is a cleaner, more elegant installation.Now, if you read the User Guide for the thermostat you probably noticed in a few places where it says "Do not use K terminal. For future use". That statement is probably true for older versions of the thermostat and/or its firmware. Honeywell Support confirmed that the RTH9580WF thermostat will work with their WireSaver module which uses the "K" terminal.The only thing you have to make sure is that your heating/AC appliance's control board does provide the 5 connections needed (C, R, G, Y and W). I suppose that some older system may not provide all connections.The installation using the Honeywell WireSaver is straight forward. The attached pictures show it all.The RTH9580WF thermostat has all the features I need and then some. If you create an account on the mytotalconnectcomfort website and add the thermostat there, your thermostat will receive software updates as they are released by Honeywell to fix bugs and hopefully to add features. You can also configure to get email alerts and you can make changes to the temperature settings, fan settings and you can even edit the schedules. This comes in handy when you are not at home. Even when you are at home, it may be more convenient to make schedule changes on your computer instead of the small touch screen.You also use apps for your iPhone or Android phone. I am using a Lumia 950 (Windows 10 phone) and Honeywell has no app available. Also I am not aware of any future plans for such an app. Not a big loss though since I can access the mytotalconnectcomfort website using my Windows Phone the same way I do it on my computer.The only thing I find missing when I compare the RTH9580WF thermostat with others is the reports. It would be nice to be able to get reports about the power usage and savings via your email. These reports would add the 5th star.This thermostat works great for me. I only installed it about 24 hours before writing this review so I have nothing to say regarding the long term operation. However my past experience with Honeywell products was great.

It was easy to install and replaced a 20 yr old Honeywell. It's been two months and so far it is working great. Initially it red two to three degrees lower than the unit it replaced. Love the app remote function.

purchased this thermostat 1 year ago (my 2nd purchase of this... we love it).. it worked perfectly until last week. All of a sudden our heat would not kick on. After hiring an HVAC tech to come take a look and replace a part on the furnace to attempt to fix the problem, it was narrowed down to the thermostat being faulty. We swapped this out with our old one and the heat is working again. Calling them regarding warranty replacement... hopefully that goes smoothly!

I replaced my two older 1-stgage home HVAC units with Carrier Infinity 2-stage furnaces and Carrier Performance 1-stage AC units. I’d had older programmable thermostats for a few years and decided it was a good time to get new thermostats now with wifi and more bells and whistles. The Honeywell TH9320 was a good choice. I am 59 and installed them myself but decided first to run new 18/7 wiring since I only had 5-wire connectivity and needed more conductors because I wanted the thermostat to control the 2-stage furnace (With only 5 wires I could not make the extra W2 connection. The furnace can control its own 2-stage heating without the W2 connection from the thermostat but in case you don’t know it that works on a pre-determined timer basis – stage 1 for a few minutes then stage 2. I wanted to let the thermostat control the 2 furnace stages directly, based on temperature differential between set point and actual room temp, so I needed more wires.) For my installation I ran a 7 wire cable and used 6 wires. Your needs may vary. The TH9320 was relatively easy to install but I would have preferred screw down terminals instead of spring lock – screws provide a more stable connection. Since the thermostat is small, probably smaller than the one you’re replacing, you will likely need a cover plate to install behind the device to hide marks and holes from previous installations. Make sure you get the correct plate. It’s not included and good luck finding the right one. I could not. I ended up purchasing two Honeywell 50002883-001 cover plates and taking a Dremel grinding tool to remove the ridges around the mounting holes to allow a flush fit. Took 5mins and fit perfect after that. I don’t know why I had such a hard time finding a wall plate that is compatible with this specific thermostat.Once installed, the thermostats came up quickly and connected to my home wifi w/o issue. After the first install I input my preferred heat/air schedule while standing there before I even put my tools up and discovered later its quite easy to edit the schedule from a phone, laptop, or pad. Once I registered the devices on Honeywell’s web site they began to update themselves. I have only had them a short while but they seem to work just fine. I do like the automatic circulate air feature and you can program on which schedule segments that will occur (wake-up, leave for work, home again, sleep). The app and web site work well and shows both thermostats clearly on my phone and laptop. What you are able to control remotely is a subset of the options available while interfacing ‘in person’ with the thermostat.There are a couple of things I hope can change in subsequent updates for this thermostat:1) I can not determine, while remotely connected, if the system is in an active state. I can tell what the indoor temperature is while I am logged in from my iPhone and if it is supposedly following the schedule but I can not tell if the system is actively cooling or heating or if the fan is currently running in recirculate mode. Would be nice and seems appropriate to know exactly what is going on at the time I check on it.2) I don’t see the capability to view overall usage over time. Would be nice to have a log or some sort of record of heat/cool/fan usage over a period of days/weeks/months.I am giving the TH9320 4 stars. It functions well and looks good. I expect/hope to use mine for the next several years. One star off for high price, spring-loaded push to lock wire connections, difficulty in finding a wall plate solution, not being able to tell remotely if the HVAC system is running, and no usage logging. Perhaps I could have taken two stars off for these shortcomings but everything is relative and the TH9320 compares well to the other leading thermostats on the market now. However, I think it could be better.

It has been a month since purchase of this product and the servers that allow you to register your device have been down the entire time. I waited a week after installation to call Honeywell and make sure the problem was not on my end and I was informed that it was known "the servers are down" and there was no estimated time of resolution.Two weeks after my first call I attempted to call Honeywell support again and after going through the myriad of menus a voice came on and said something to the effect of "due to high call volume we are hanging up on you" and then it hung up -thanks Honeywell!The reason I paid a premium for this device is for it's premium services - mobile access. Otherwise it works exactly as my old "dumb" thermostat did except I no longer have manual control of my HVAC fans as I had no C wire- the fans will only run when the system is heating or cooling (a compromise I was willing to make for the promise of mobile control).Until this is resolved I would not advise purchasing this unit.Update:Servers are up and the thermostat works as advertised. The android app has worked for me consistently. Overall I'm satisfied with the choice compared to other "internet of things" thermostats.Update 2: After a year I'm happy to upgrade this to 4 stars. Solid performance, no issues connecting remotely. Happy with my purchase.

Excellent product, in my case for remote control from thousands of miles away for a part time residence. Only caveat thus far is that I put it in Away/Vacation mode before leaving and, while I can access status on line, can no longer control the device. Not sure why this was designed this way, but there it is. I'll have someone access it on site and fix that. Compliments to Honeywell for having phone support on Sunday either 855-733-5465 or 877-271-8620 - wade through the menus.

Update to my review below. I just installed my thermostat and I LOVE it. It was VERY EASY. The way I described below is how I set mine up. I also used the "business" instead of "home" and "Heat Pump" options.*****************************************************************installed of "Forced Air" options. Someone here said the "business" option gives you more options.My current thermostat is an Aprilaire unit. There are 6 wires connected to it (C, W2/Aux, R, G, Y and W O/B). The installation manual for the Honeywell WiFi 9000 shows 5 wires being connected (C, R, G, Y, and W O/B). I believe my 6th wire should go in the "W2" slot of the Honeywell 9000 but I don't want to make a mistake with my AC/Heating unitI called Honeywell and the guy the answered the phone rejected to help since the Honeywell 9000 is a contractor version. He said I HAD to hire someone to install it. He said he is not allowed to help with this unit. He was also a bit rude like being bothered by my call. I really wish they had the "rate your experience" after the call but... oh well.(1) be aware you might not be helped by Honeywell. I might give them another call and see if someone more helpful answers the phone this time.(2) The Honeywell WiFi RTH9580WF, according to reviewers here seem to be the same as the 9000. Part of the instructions for the RTH9580W appear to be more clear to understand. So far, I'm planning on following the wiring based on this model. I hope I don't regret it (cross fingers).My system is a Heat Pump (outside unit), AC unit in the attic ( believe this is called the furnace/HVAC). The inside unit in attic also handles the emergency heating. I believe this is where the 6th wire should be used, not shown on the WiFi 9000 installation guide.The unit itself arrived promptly and in good shape. It's certainly very different than my old thermostat (see pic of old thermostat with 6 wires).

I bought this in conjunction with a new furnace. The install was very easy and I had this wired in less than a minute. It was up and running on my network in about 5 minutes. The biggest pain is the setup on Honeywell's website. It would be nice if the registration was quick and easy but they require a lot of information which drives me crazy. That being said the app was simple to install and setup. The integration with my Amazon Echo wasn't as easy as I thought it might be but again, these parts of the setup don't impact the basic usage of the thermostat. So minus one star for the app/web configuration part of the install.

The one thing I don't like which is why knocked off an extra start is the temperature is off by 2 degrees. When the thermostat is set to 72 degrees my old thermostat, as well as two AcuRite thermometers/humidity monitors I put in the same room read 70 degrees. The humidity guage is also off by around 8%. It really doesn't affect the furnace operation and is more annoying than anything else so I'm pulling a star on this review.

Disconnects from SmartThings about once a month. I purchased this thermostat because I preferred the aesthetics over others on the market. However, about once a month (because of software updates I presume) it disconnects from SmartThings and I have to go through the painful process of reentering my Honeywell login information to get it back online.

Additionally, as other reviewers have mentioned, the mounting bracket is poorly designed. You have a 50/50 chance that your thermostat will hang loosely because the bracket doesn't grab the thermostat well enough.

Fancy version of a standard stat. Wish I would have bought the Nest as it does metering, motion, phone detection, etc to truly drive cost savings. This item just gives you remote access to the unit nothing more than that in my opinion.

I should have looked at new Nest reviews, since the updates and changes that product is solid. Three of my friend have it now and it is 10x the product this is.

Easy to install, requires common to be hooked up to power it. Had to dig that out of the wall as many stats do not require the common to be used (including the Nest).

I will be moving this stat to the other zone and adding a Nest to my main zone. They wont talk but that is fine as the secondary zone doesn't run much in this house.

I researched the thermostats to death. I had no reason to replace the old Honeywell thermostat that came with my house. It looks like it is the original thermostat that came with the house when it was built 30 years ago. So in my research I considered the Nest thermostat (and I really wanted to get it), but I settled on the Honeywell mostly because I wanted the option to set my own schedules rather than have the device "learn" what I like.

I purchased the Honeywell 9580 in June 2015. I promptly installed it on my wall when it arrived to replace the original Honeywell unit that came with my house. We added the device to our wifi network. My SO and I then downloaded the "Honeywell Total Connect Comfort" mobile app, configured the account, and created our schedules from the app. At this point there was no reason for us to ever touch the thermostat on the wall again.

In fact, we didn't touch the thermostat after we had the mobile app working. We enjoyed the ability to adjust the temperature, power state, and schedule of our fancy thermostat from anywhere. Hell, we even turned it off and on from the airport when we were going on or returning from trips! It's wonderful to come home to a sufficiently cooled/warmed house!

Then the problem arose.

One morning (Jan 2, 2016) I came downstairs to find the the color scheme had changed on my unit. I had asked my SO if she had changed it, but she said she hadn't. I tapped the screen to change it back to the color scheme that we prefer. To my surprise, it changed back to our color scheme immediately when I tapped the screen. Odd? I went about my day.

Later the same day I received an alert from the "Honeywell Total Connect Comfort" app stating that my Honeywell device was no longer connected to the internet. Wow! I'm impressed! Great feature indeed! So I wander over to my thermostat and discovered that the screen was black. Very odd. I tapped the screen - nothing happened. I tap the screen again - still nothing happened.

So then I called Honeywell Support. They had me pull the thermostat off the wall and check the circuit breaker and also check to see if there is power across a couple wires. The circuit breaker was fine. There was no power across the lines. Honeywell Support then told me to contact HVAC to find out what's wrong with my furnace.

I contacted a local contractor service which came out the following day. They "jumped" my thermostat, installed my old thermostat back on the wall, and told me that one of the transistor caps is damaged on the fancy Honeywell 9580. Sure enough, it fell out just flipping the thermostat over.

We called Honeywell Support again to report that the device is still not working after HVAC checked it out and that one of the transistors is now "broken". Honeywell Support essentially blamed us for the physical damage and explained that they would not honor their warranty as a result. We explained that the thermostat worked perfectly for the 6 months that it had been on the wall and the only reason it was off the wall was because it STOPPED WORKING and a HONEYWELL SUPPORT REP instructed us to take it off the wall. So how does it get damaged sitting on a wall for 6 months? Honeywell provided us with the email address of a "manager" named Paul Arntzen (case # 00168634) and instructed us to take pictures of the device and email that "manager." We emailed Paul on January 4th. We received no response. We emailed him again on January 8th. As of today (January 16th, 2016), we still have not received any response.

IN SHORT
The device worked perfectly for 6 months and we did love how it worked. However, due the to crappy support from Honeywell, we will not be purchasing Honeywell products anymore.

EDIT
We eventually did get it replaced for free, but it took at least a dozen emails and several phone calls. YMMV. The way that we got results was that we used the "feedback" option on Honeywell's website. Someone got in touch with us, provided us with an email address of a manager and asked us to send pictures of the device and details of our story. We did. Someone responded and asked for our address. Shortly thereafter a brand new device arrived at our door. We put the new device into operation and it has worked without issue thus far. We kept the original Honeywell thermostat (30 years old and non-digital) just in case we get a repeat issue. I ended up selling the old broken thermostat on eBay for a decent amount of money - the person who bought it apparently fixed it and he is happy with it. Changed from 1 star to 3. I can't in good conscience give this a 5 star rating due to the customer service.

If you have a Gas Furnace with Hot Water Heat -- BEWARE -- nowhere will you read this on Honeywell's website, however you will require an alternate 24v power source (not run off the furnace). Why? Because the Gas Furnace will briefly power down when a "call for heat" happens. This reboots the thermostat. Called Honeywell -- They knew about this problem immediately -- get calls all the time. However, you need more than just the "C" wire to solve this problem. You need to run a 4th "RC" wire, and go buy a 24v transformer to power it. This was a very bad decision by Honeywell not to tell people about this upfront. Luckily I ran 2 extra wires, but if you run just a C wire you will be quite upset to find you will need another wire run. Honeywell could have added a $1 capacitor to the design to solve this problem, however why do that when they can have me run more wire and buy a $20 transformer.

Also, for those thinking this will capture utilization metrics, like "hours on per week", or an activity log of some kind. Nope. A $200 thermostat that looks pretty. Guess I'll have to contact the NSA to get that data.

The panel housing (plastic) attaches to the wall mount (plastic again) with three tabs (plastic!) of exceedingly cheap construction. When you press the screen to make any sort of adjustment, the unit wobbles and jiggles. Inexcusable on a thermostat that costs more than some air conditioners.

Honeywell is missing the opportunity make it a great thermostat. It does everything it says just like it should, but it lacks nice features like humidifier control, geofencing, or remote sensors. It goes through the trouble of measuring inside humidity and polling accuweather data for outside info, but won't control a humidifier. The difference is two more screw terminals and a relay. Probably $1. Instead, you have to buy a honeywell humidity controller and wire a whole separate item for another $60. How hard would geofencing programming be to implement? Not very. Would make a good thermostat great and save the consumer extra utilty costs to justify the price of the thermostat. Finally, its a wifi thermostat. Why doesn't it partner with wifi remote sensors? Who knows. Again, another opportunity for greatness missed.Personally, i'd prefer a feature rich wifi thermostat without a display of any kind (app only) for under $50. Afterall, most of the features on this thermostat are simple software upgrades that should exist on the lower cost wif honeywell model but don't. Why? Upsell you to this one at double the price.

I recently looked at buying a Nest, Lyric, or this thermostat (Honeywell 9000). After a great deal of reading, I ruled out the Nest. While I think the Nest is the nicest appearing of the three stats, I don't like the Nest's allowance for wide temperature offsets/overshoots. It seems the Nest sometimes has a mind of its own controlling the climate system. Plus the Nest is all solid state, without relays.I bought a Lyric thinking it would be the stat for me. After fussing with the Lyric, I returned it. It is a good stat, but I just didn't like certain features. Geofencing on it seemed only semi-reliable. The Lyric is solid state too--no relays. It felt overpriced. I wanted a little more control over my stat's operation, so I decided to give the Honeywell 9000 a try.The Honeywell 9000 so far seems to have a good balance of features and familiarity/reliability. This thermostat may not quite have the neat factor of the Nest, but it still looks pretty darn cool. With a white bezel and compact size, Its design is understated elegance. Installation is a breeze. Documentation is very good. Instructions are easy to follow. The thermostat practically sets itself up with easy to navigate wizards/menus. Setup does not require an app, but programming setbacks are a snap with the online wizard. I like that this thermostat is a more hands than the Lyric or Nest. It is possible to fine tune it more than the other 2. This stat shows the humidity on the display too. Oh yes, this model has relay(s) which to me are less likely to damage heating and air equipment in the event of failure. Sometimes the touch screen on the Honeywell 9000 feels like it is a little "first generation", so there are indeed a few tradeoffs. All in all, I like this stat a lot. Honeywell did a really good job with the 9000.Addendum: After owning this thermostat for several months, I've become annoyed with how it handles auxiliary(stage 2 heat) in this very cold weather. Unfortunately there is no way to change temperature swings or cycle times. As such, this stat is short cycling my equipment.A word of caution--this stat is a very basic stat with zero advanced installer options. Buyer beware.

Just got this thermostat today and installed it.****I just want to start out by saying that the current top two yahoos posting a review saying this thermostat has adjustable swing times IS DEAD WRONG! I took their word for it and ordered this thermostat based off of their reviews.****Yeah I'm a moron for taking their word on it and not calling the company etc etc etc.. I just wanted to put this out there so no one else made the same mistake. And for you two or anyone else that wants to argue the fact.. No, offset is not a swing time setting. The offset is to adjust the temperature + or - if the thermostat is off right out of the box.So quickly first impressions of the thermostat...Pros:Beautiful, great customization of screens and program settings, WiFi is awesome, really cool to check and change temps from phone/web, Touch screen rocksCons:No swing setting (Huge for me), Can't program the unit from phone/web. Smaller than most older thermostats (not that this is bad, just be prepared to fill holes and touch up paint)

I have mixed feelings on this unit. On the one hand it is easy to program and override as necessary. On the other, you cannot lock/unlock the screen remotely, something I really wanted. Also this particular model is the "contracter" model which has 2 access codes, one which I cannot change. This really defeats the point of the whole lock idea as that code IS ON THE BACK OF THE UNIT!

Update 5/12/15: DOWN GRADED from 4 to 3. The constant "site under maintenance is a true pain in the ass. This is why I would recommend to stay clear of anything that ISN'T a true IP based device because you have NO control over their site. This is now becoming a true nuisance. It's a great device, but the main feature (being web based) is utterly useless if you can't access the thing for hours at a time. Now it's becoming A LOT more frequent.Get your act together Honeywell or step aside.Update 12/22/14:Love this thermostat...My wife is pregnant for the 3rd time and this time, she's having weird "cycles" of hot and then cold. To top things off, she's had some complications, so anything to make her life a little bit easier is extremely beneficial . Instead of having to walk all the way upstairs to adjust the thermostat whenever she gets a "cycle", she whips out her Iphone5s and just adjusts it. One thing that is often overlooked, is the fact that, no matter what she changes the temperature to...as long as she doesn't "Switch that temperature to be permanent", it'll go back on it's schedule once one of the programmed times is hit. It's another convenience type thing that you don't appreciate until later...well at least we have.It has saved us money as well. Roughly $35/month off our bill for the past 6 months. Figure it has just paid for itself($210) on month 6. Now we do live in TX...so our most expensive electric months are now in the rear-view mirror so I doubt I'll see any real savings until end of April/May now...but nonetheless...this device is now paid for. Being able to adjust the temperature from anywhere allows people who are serious about saving money, to actually achieve it...The programming feature will still save you money, but to squeeze that extra few dollars a month out, just be a bit more proactive.Old Review:Easy to install, works as intended, looks great. It will save you money if you figure out a schedule that works for you.For some reason I was expecting it to be an IP thermostat like the Foscam cameras, where they have their own built in program where it doesn't connect to a big corporation and you have to open the port to connect out. However, I was wrong. In order to use the web service, you have to agree to Honeywell's ToS, which I'll summarize here for you, "We own the information from your thermostat and can sell/do anything we want with it at will." So if you don't want that information on the web, don't use the web features. It's still a good device even without.

I have owned this unit for less than two years, and it recently began reporting our indoor humidity quite inaccurately (6-8% lower than actual level). I contacted Honeywell customer "service" and received this reply:

"RTH9580WF does not have the feature of controlling humidity from the thermostat, it just displays the humidity settings on it. There is no option to calibrate the humidity settings on the thermostat. This thermostat can display 5-6 degrees off when compared to a hygrometer.

You may get the unit replaced from the place of purchase, however it will display an off of 5-6 degrees."

Be advised, it is inaccurate, and Honeywell will do nothing about it.

I purchased this item in April 2015. It worked great, I loved using the app to change the temp settings. One of the reasons I bought this particular model was because it had a lock screen, so I could try to keep the teens in my house from changing the temperature (all claimed it wasn't them that changed it). That feature is very poorly done, very difficult to unlock the screen when needed, then you have to go back in and change the settings again to lock it. Better would be to unlock it then have it time out after a few minutes.
Anyhow, I was still happy with my purchase, and even bought another Honeywell thermostat for my downstairs, though not this model,just a basic wi fi model, so I could control my whole house with the app. The basic model is about half the cost of this one, and does everything this one does, with the exception of the problematic lock feature. So it doesn't have the fancy touchscreen, not really necessary for function.
Anyhow, just a few months after I purchased the second thermostat for my downstairs, this one just failed. Unfortunately, the 12 month warranty is 5 months expired. I am not sure what actually failed in it, but it would turn on the compressor when the air should come on, but then it would turn off again just a minute later. Using the downstairs unit the compressor would stay on as it should. I confirmed that it was the thermostat and not something else by re-installing my old basic thermostat that I had kept. Things worked perfectly with that thermostat installed, so not my HVAC unit.
This is a lot of money for a thermostat for it to last less than a year an a half. Now I'm upset I bought another of the same brand for my downstairs, as I was trying to avoid using two different apps to control my two units, but I can't bring myself to purchase another Honeywell at this time. Maybe I'll get a Nest.

Bought this unit to replace an older Honeywell Wifi thermostat because I wanted scheduled fan control times to circulate the air. Install was a breeze (although paint and drywall touchups were needed; this unit barely covers a 1 gang box) due to already having the correct wiring.

The touch screen is a bit annoying .. using the back of a pen or a key is much easier than trying to use your fingers sometimes.

Biggest complaint is the temperature sensor. As other reviews have noted, it's a bit schizophrenic. It's also very slow, or very fast to respond. In most cases, you will experience a 3-5 degree fluctuation in the room temperature before the sensor even registers a 1 degree change. If you can handle that, then this product might be for you. If you rather have a thermostat that works but doesn't look as pretty, check out some of the older (cheaper) Honeywell Wifi Tstats.

I have 2 of these, and they behave the same. I have several older models also installed in other buildings which are much more stable on the temperature readings, resulting in much better climate control. The lack of stability isn't awful, just annoying. I'll keep using these because the scheduled fan control is an important feature (which I'm sure they could add to their older models, but they'd rather force you into upgrading to a far less superior unit).

Purchased the Honeywell Wi-Fi Smart Thermostat in January of 2015. Worked fantastic for 9 months then my spouse reported that the display was blank one evening while I was away ... sure enough I could not connect to it via my smart phone during this 'outage'. A few hours later the unit came back to life - no explanation for the system outage. During this time, the thermostat is unresponsive ... so temperatures in the house start to get uncomfortable very quick. It's been doing the same thing for several months now ... sometimes it blacks out 3-4 times a day while other times it seems to work okay for several days in a row. Very disappointed with the fact that I cannot return the item even for a partial credit. Something is certainly wrong with it ... I've reset it by removing it from the wall ... no help at all.

Well it worked great for just over a year. Bought it in January 2014 and it stopped working today, April 11 2015. It has a 1 year limited warranty so its out of warranty, but it states, "This warranty shall not apply if it is shown by Honeywell that the defect or malfunction was caused by damage which occurred while the product was in the possession of the consumer." Honeywells customer assistance definition of that is once you buy it, install it, and it works, warranty is void.

For the most part though for the last year my bills have been almost $30 to $40 cheaper this past winter than last. Never went a summer without the Honeywell in this home so I have no comparison there. It does what it is suppose to do, but mine pooped out just a couple months after the warranty. My problem was that it would not turn the furnace on anymore. It would work with the AC and the fan. I put in my old thermostat that I still had luckily and it works just fine. Put Honeywell back in after that, and it wouldn't work.

Pray you don't have any problems. As like others, Honeywell will not honor the warranty if you installed it yourself. Its a shame the the warranty support is nonexistent, other wise its a nice product and the app is pretty decent.

Worked great for three months, then electric bill tripled. regular heat would come on, heat pump, then in 30 seconds strip heat came on. had now idea till received electric bill. removed and replaced.

Struggles to register temp within 3 degrees of actual room temp.

I didn't give it 1 star because I love the screen display and the easy to use menus. The problem is that it just doesn't control my A/C efficiently--it short cycles my compressor up to 8 times an hour. This constant cycling would wear out my compressor in no time. There is no setting on the thermostat to control cycle times or swing times. When the A/C shuts off, the indoor temperature on the display drops 2 degrees, even though the actual temperature is 2 degrees higher. Within a minute, the indoor temperature on the display goes back up 2 degrees where it should be. Sometimes the A/C will cycle on when the indoor temperature on the display is lower that the set temperature. I'm sending this turkey back and returning to my old Honeywell RTH7600, which works better, but without all the whiz bang features of the TH9320WF. After all, if the high tech stat won't control my A/C properly, why have it. Looking Pretty Isn't Good Enough!

Setup an account [...] and follow a few setup questions on the touch screen thermostat. Just need to make sure you have a C wire 24 volts. It only took me a few minutes to get the thermostat registered. Really like the online program and the phone app.Will buy again next time!The thermostat failed 18 months since purchase. It has a short and blew a fuse. Honeywell will warranty it however it will take 6 weeks if it is in stock. So I am now stuck buying another one since I cannot wait 6 weeks!

Although the description states there is a five year warranty, you are not able to exercise the warranty if you have an issue. Honeywell makes you go through your installer or dealer for warranty and will not honor it directly. Honeywell makes a similar model for homeowner installs. Buy that one.

I don't know who else bought this thermostat but I am wondering if your unit turns off a random times and then turns back on. Mine is doing it but I can still use my phone to turn my heat on but it resets my schedule that I had programmed. Weird I know. But is anyone else having this problem?

This product has many nice features;
- It installed easily / instructions were great!
- It looks great on the wall
- It's easy to use

However, and this is a BIG and ultimately fatal however
- If the product looses internet connectivity, it may not, and probably will not, reconnect without personal / onsite interaction.
- This was confirmed with a call to Honeywell tech support

I purchaced this for a vacation home where I could remotely monitor interior temperature over extended away periods of time. During the last Honeywell initiated internet update, I lost connectivity and have never been able to reconnect, making this product useless. I have a Nest remote thermostate in our other home, and have never had this issue, even with internet outages. Unless you plan to always be present to reconnect your thermostat from time to time, I recommend you look at other brands

Update: Problem solved / replaced with Nest!

Note: I had requested to return this thru Amazon back in November, even though I could not do so until I returned to our vacation home in June. June was well past the allowable return period. I printed out the return label in November. Removed and returned the Honeywell product when we got back to our vacation home and received full credit. Amazon rocks! Why would you ever buy from anyone else!

This thermostat did not work - at all! It heated the house rather than cooled it. We tried it a few times and each time it was a bust! We had to put our old one back on. On a side note - the customer service was really good. And so was the return.

Very disappointed. It was awesome while it worked but it died after 14 months. Honeywell support was horrible and their response was to simply buy another one because "it happens". Well no thank you. Replaced it with Nest and so far I'm very happy. Especially since they have a 2 year warranty!

Worst customer service experience I've ever received. I was on hold for 45 minutes until I got a supervisor. I called because my unit broke and was still under warranty. I called once and troubleshooter with Honeywell's tech department and the unit still did not work. I called back this second time and was told I had to go through Amazon.com for the warranty. When I called Amazon.com they told me it was Honeywell. So I called back with Amazon.com on the line, which is when I was on hold for 45 minutes. They still haven't honored their warranty because they need me to troubleshoot it AGAIN! I'M GOING NEST OR ECCO NEXT TIME!! NOT WORTH MY TIME AND AGGREVATION.

Do not buy this. It is only under warranty if a contractor installs it, which is nowhere on the description. Mine broke after 2 years and now I have to buy another one because Honeywell will only replace it if I have a contractor install it. Crazy.

I purchased and installed this unit on my own. Once connected the unit did not power up. I called Honeywell customer support and am told this unit is only to be installed by a licensed electrician. Otherwise the 5 year warranty is voided. They were "unable" to help me further. Amazon, why is this unit being sold to the public with absolutely no indication of this stipulation?!? I am told by Honeywell tech support the RTH9580WF is an "equivalent" unit meant for residential use and DIY installation.

WIFI. Horrible Wifi implementation. I love Honeywell but this is pure crap.The thermostat will not connect to ANY wireless network if your SSID (network name) has any spaces, special characters, or is too long (I don't recall the length), and it doesn't matter how new or old your thermostat firmware is.Mine arrived with firmware 02.01.07.00. With this firmware, you cannot use numbers in your wifi password if you are using WPA2_AES. For example, 12345678. The device will say "Connection Unsuccessful" " The password you entered is invalid". However, if you change the password to "abcdefgh", it will connect. According to the WPA2 standard, passwords can be any combination of printable ASCII characters (basically, anything that is on your keyboard) that are 8 to 63 characters in length. The Honeywell cannot handle this. Tech support doesn't have any solution for this, according to them.FIRMWARE. Once it connected, the firmware updates started rolling in. After a few minutes, I was up to 02.03.00.00. What is the newest firmware available, you might ask? There isn't anyway to know and Technical Support will not tell you. They also cannot push updates if you aren't receiving them. Anyways, now with this new update, you cannot join ANY wifi network using WPA2_AES regardless of what password scheme you try. You must roll back your security to the less secure legacy WPA TKIP. WPA isn't considered secure anymore by any respectable IT administrator.TEMPERATURE. There are also several other issues with this thermostat. I had to adjust mine to "-2°F" in the Advanced Options menu to get a close enough to accurate room temperature. Several owners report that the temperature isn't accurate no matter what they do. I have noticed this as well and it has not been addressed in any firmware releases. This is likely because it is a physical hardware design failure. For instance, when the device boots up, the reported internal temperature rises about 5°F. If the back-light is on for too long at any decent brightness, the temp rises 1°F to 2°F. The temperature rise also occurs during automatic firmware updates.DEAD THERMOSTAT. Speaking of firmware updates, you have no control over them whatsoever. Did the power flicker, glitch, or brownout during an automatic firmware update during the middle of the night? All you know is you woke up or came home from work and your thermostat won't turn on. Congratulations, you know have a "bricked" thermostat that is useless. Hopefully it wasn't in the dead of winter and all of your pipes froze and exploded. You can bet your bottom dollar that Honeywell won't pay for any of the damage, or even give you a new thermostat. It's in the user agreement that you must accept to use this thermostat.SECURITY. Would you like to know if you have the latest firmware? Too bad. It is important to know if you have the latest firmware from a security standpoint as vulnerabilities are reported all the time and it is up to the manufacturers to publish security updates to their firmware. Want a changelog from Honeywell to see what they are fixing and what they aren't? Too bad.FEATURES. It doesn't have any options for automatic or scheduled "circulation mode". You have to do that manually (why? It's friggin digital!). You can't calibrate the thermostat past ±4°F. You cannot turn off automatic updates and you don't get notified of any updates. The outside temperature and humidity information on the display is derived over the internet and often gives error messages. According to Honeywell Technical Support, there is nothing wrong with the thermostat and all the blame rests with accuweather.com. The thermostat also has this awesome feature where it drops the wifi connection randomly, even though it is only 25 feet away from a Netgear R7000 router. The thermostat also don't mount securely to the wall. If touch the thermostat too hard, it separates from it's mounting plate on one corner and you must click it back into place.SCREEN. Way too small. Deceptively small. Even the $15 trac-phones you get nowadays have bigger displays. The display also has a weird display refresh rate. I can see very high frequency flashing or jittering on the screen. I guess it could be the backlight for the display as well. They could be using PWM to control power to the backlight LEDs, hence the perceived "vibration" of the screen. I would only expect this in cheap Chinese gear.BOTTOM LINE. I'm switching back to Honeywell's 7-Day programmable thermostat without Wifi, the Honeywell RTH7500D Conventional 7-Day Programmable Thermostat. It has saved me THOUSANDS of dollars since I have owned it (I used to live in Guam where some peoples electricity bills were $800-$1000 A MONTH! Mine was under $200. I like Honeywell in general but the 9000 series thermostat is just pure fail.And yes, I have contacted customer support so please, Honeywell customer support reps, please don't leave me a "copy and paste response" telling me to contact you knowing darn well you don't have a solution. If you do, I'm all ears.

This thermostat is horrible. I installed the thermostat last winter and it would take forever to get to the temperature (just the last one degree up to the set point), so the unit was running far more than the old one. And then when it finally got to the temp, it would jump about 3 degrees above the set point. As far as I could see there is not adjustment for that and the MFR told me that also. Also, I could never get the A/C to work correctly as the unit always erred out. Of course, all these things happened after the date at which I could return it. So now I have a $200 thermostat that sits in a box ready to be thrown out.

DO NOT BUY THIS ITEM.This item is listed as having a 5 Year Warranty. I purchased 2 of these Honeywell Thermostats from Amazon.com December 2014.They were installed and worked until June 2015. One Thermostat shorted out causing the fuse on the air handler to blow.I contacted the Honeywell Support line and was repeatedly told that the item is a 'Contractor' model, it should not have been sold directly to a residential customer, should have been 'professionally installed, and that they refuse to honor the warranty.THERE IS NO INDICATION THAT THERE IS NO COVERAGE FOR A RESIDENTIAL CUSTOMER IN THE WRITTEN WARRANTY WHICH COMES WITH THE PRODUCT OR IN THE PRODUCT LISTING ON AMAZON.COM.I contacted AMAZON.COM who agreed to do a product replacement, but, did not agree to work the issue with Honeywell, or alter the product listing.The replacement thermostat just arrived. Unfortunately, the replacement is an open box return which has visible scuffs, glue on the back as if previously incorrectly installed, and most importantly, missing the MAC address card needed for connecting to the internet.I Called AMAZON.COM for a 2nd replacement and was told they cannot issue a 2nd replacement that I would need to get a refund and re-purchase the item.

Well, to make this review short, Honeywell should stick with what they know and not venture in areas where they lack basic expertise and I am talking here about SW development. This product has so much potential but it is very poorly designed and supported. Its indoor temperature indicator is grossly malfunctioning: so many times, although the house was getting hotter, it was simply indicating same initially temperature, forcing me to manually stop it. Other times it is jumping few degrees higher or lower without any reason. If a thermostat cannot provide its basic functionality right, who is even interested in its additional features. Which by the way could have been much much better implemented.Have been tested this version as well the 9580, consumer version, both have the very same basic issue, look for this on forums or other Amazon reviews. Big disappointment. Will get Ecobee Smart Si a try
