Great Thermostat
June 1, 2017
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.
Nice Thermostat! Glad I purchased it.
February 14, 2017
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!
Nest thermostat vs. this Honeywell thermostat
April 7, 2016
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!
Nice, cool (haha) thermostat!
October 22, 2015
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.)
Easy For Anyone To Use, Anywhere
October 21, 2015
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.

Works perfectly with Alexa
October 1, 2017
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.
Not so Smart
January 21, 2017
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.
Great product worth the money
July 6, 2016
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.
Great T-Stat; Installation a little tricky.
June 13, 2016
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).
For Water Furnace geothermal users: get someone competent to install.
March 13, 2016
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.
This Thermostat Works Great
February 16, 2016
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.

Clean, Easy To Install And It Works But Not Accurate In Measuring Temp & Humidity
December 31, 2016
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.
September 25, 2016
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
July 23, 2016
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.
worked for 6 months, died, honeywell refused to replace, warranty not honored
January 16, 2016
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.
Pretty but caution !
November 13, 2014
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.

It works, but it is not accurate.
February 19, 2017
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.
A lot of money for a thermostat that lasted less than a year an a half.
September 24, 2016
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.
Thermostat with it's own mind.
May 12, 2016
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).
Worked great for 9 months then began blanking out for hours at a time.
December 26, 2015
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.
Worked for 15 months
April 11, 2015
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.

I don't know who else bought this thermostat but I ...
March 8, 2017
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?
One fatal flaw
December 8, 2016
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!
Didn't work for us!
July 30, 2016
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.
Disappointed
February 19, 2016
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!
HORRENDOUS CUSTOMER SERVICE
June 16, 2015
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.
