Installed the first one. The wi fi was good, looked impressive however it would not calibrate. I would set it for 76 and it would keep running. Finally getting so cold I would have to turn it off manually. Same thing on heat cycle. Called tech support they claim unit is defective. Sent new one and same results. Took back for a refund and got the Sensi. Works great and is less money. also have it hooked up to my Amazon Echo.

I bought this thermostat to replace a Nest which I had gotten several years ago. I found the networking capacity of the nest was a bit touchy and frequently drops limited it's wireless capacity. The Honeywell appears rocksolid and very easy to use. we have a Honeywell alarm system and the thermostat inrefracted very nicely with it.

Pricy upgrade that really was not necessary, but it has made a huge difference for us, particularly in being able to adjust temperature without walking to thermostat and in being able to see temp easily from a distance. Easy to install, easy to figure out how to use. Have had a month or so with no issues. Have not switched to heat yet. Will update if any issues then, but it seems pretty straightforward.

Update from before - I contacted Honeywell by email and received no response finally called and they said could solve problem, asked me to disconnect wi-fi and they would take care of problem and call me back in 15 minutes. Glad I didn't take the faceplate off as he suggested because it's now 14 hrs later and no call. So would have been without AC all night in 100 weather. They apparently fixed it because I could finally register it but apparently all the wi-fi does is let you look at and change schedule on the thermostat. BUT the primary reason I changed out the thermostat is because I wanted one that would automatically change from AC to heat when needed. This one was supposed to do that but apparently does not. Directions say automatic option depends on how it was installed so no idea what that means but it doesn't show up on this thermostat. So I am stuck with this thermostat that has already cost me almost 400.00 to buy and install and it does nothing different than the old one. Can't afford to replace now so will leave it in till I can afford to get one that does what it says - NOT a Honeywell if I can afford it.

Here's another in a long line of well designed Honeywell thermostats. It works well with my multistage furnace and air conditioner, and does everything as advetised.

Rated 1.0 out of 5.0 by STguy HORRIBLE TECH SUPPORT!
The thermostat functions reasonably well BUT it cannot be used with an Iphone 6s. I have an Iphone 5s and it works fine with that but NOT the 6s. I have called Honeywell a number of times. Each time we go through the same steps to no avail. Each time I am promised the issue will be escalated and i will hear back from them but also each time NOTHING HAPPENS!! I have given them plenty of time to deal with this issue but apparently they don't care so it's time to write bad reviews and save others from the frustration.

Rated 2.0 out of 5.0 by TF Just wanted to cool
Not sure if I have a defective thermostat , we are in Florida just want the house to stay cool
Set at 74° If the temperature falls below's the heat kicks on to bring it back to 74°
Not sure if I'm wired incorrectly or if it's the thermostat have rewired it a couple times
Care less for the heat to kick on when it falls below 74°

I have used Honeywell thermostats for years and recommended them to friends. Due to the Honeywell brand I was happy to purchase this new thermostat. I installed the backing plate without a problem. The material used to construct the backing plate and thermostat is flimsy and could not keep its shape. The thermostat would not lock into the backing plate. I wasted my time and had to reinstall my old thermostat.

Rated 1.0 out of 5.0 by Franny Not a good thermostat
I only had this thermostat 3 weeks. I love the look of the thermostat but it doesn't read the temperature in my home correctly. It can be on a lower temperature matching the read of the house then all of a sudden it jumps up 2 degree. This has caused my ac to keep running. I also notice that when it is hot, the thermostat will not cool my house down past 82 which keeps the ac running. If I would have known all this, I would never purchased this thermostat.

Rated 2.0 out of 5.0 by TP30082 nice try, but . . .
I bought this thinking it was a decent less expensive alternative to the Nest thermostat I have at home. Key features for me were being able to monitor the thermostat remotely and lock the settings as this was for a rental property. I wanted to be able to program the thermostat at two hour intervals throughout the daytime so that my tenants could not leave the A/C running all day. Design was nice and build quality was pretty good. The touch screen seemed a little flimsy though. Setting up the unit was easy enough but when I started to program the unit, I realized that it only allows for four setpoints throughout the day - wakeup, departure, return, and bedtime. The Nest thermostat is a little bit more flexible.
HD took it back in exchange for the Nest, no questions asked.

very nice thermostat I work in the hvac field and bought this thermostat cheaper than at supply house.This thermostat is very easy to set up and operate and at a very good price.but you do need to have an extra thermostat wire or purchase a wire eliminator.

Rated 3.0 out of 5.0 by Steve Very nice but lacking 1 very important feature.
I have been using 2 Nest's since they were introduced. It is a nice T-Stat but I don't like the fact it doesn't have a HOLD feature. It can be very annoying to say the least. I decided to get the Honeywell's and I really like it. However, you have no way of knowing the usage. The whole idea of these T-Stats is to allow you to save energy. How are we supposed to know if we can't see the usage? I will be returning these and am going to try the Ecobee.

Rated 1.0 out of 5.0 by TM Wont measure temperature acurately
No problem setting it up and I have had it for about a year but for that last month or so the temperature reading in inaccurate. Set it at 76 and it runs the AC forever. Turnoff the AC, temp jumps to 78 int he room. Turn on the AC and temp goes to 79, then when your not looking its at 76. Seems this problem goes way back to 2013 after reading the reviews. Time for another thermostat. Maybe the nest this time. Honeywell, you are a major disappointment.

THIS IS THE SECOND HONEYWELL WIFI THERMOSTAT THAT I HAVE PURCHASED. IT IS VERY EASY TO INSTALL AND GIVES THE HOMEOWNER MAXIMUM FLEXIBILITY TO CHANGE HEATING OR COOLIN SETTINGS TO MATCH ANY CONDITION.
SETTING UP THE SCHEDULE IS SUPER EASY AND MUCH QUICKER THAN OTHER THERMOSTATS THAT I HAVE OWNED.
THE WIFI CONNECTION ALLOWS FOR CHECKING CONDITIONS AND MAKING ADJUSTMENTS WHILE AWAY FROM HOME. THIS IS PARTICULARLY USEFUL FOR THOSE WHO VACATION FOR EXTENDED PERIODS.
I HIGHLY RECOMMEND THIS THERMOSTAT.

Rated 4.0 out of 5.0 by LAGirl Love It
With everything going in the direction of all things "smart", this has to be one of the best smart options out there. I had a very nice Honeywell 7-Day Programmable Touchscreen thermostat which worked just fine; however, there were times when I found myself away from home unexpectedly only to have my programmable thermostat heating and cooling as it was scheduled to do. Granted in the fall and early spring it's wasn't such a big deal since the unit won't cycle on as often if at all but the winter and summer months were a different issue.
Now with my new Wi-Fi Enabled Thermostat whatever comes up is handled a swipe on my mobile. My RTH9580 would be a 5-star device but there is something going on with the firmware which keeps knocking out it's ability to read the outdoor temp through the 3rd party, AccuWeather I believe and it will continue to show "Waiting for Update". Once the unit is removed from the faceplate it will reset itself but that was a one time chore for me. According to Customer Service they are in the process of correcting this issue but in the grand scheme of things it's not a big deal but it is a feature I enjoy.
Now for the pretty stuff, the slim design is very slick and the option to change or even customize the background color is over the top. I really like that I can still see the display even when in power saving mode. However, one of my favorite features is its "timer like" ability. When you change the temp, it allows you to set it to hold that temp for X amount of time or until your schedule kicks in and this feature is also available through the app. Another great feature, No More Batteries. Although I needed my electrician for the install it was well worth it.

Rated 3.0 out of 5.0 by 2centsandmore Question ...and review
Does anyone have trouble with setting the temperature above 20 degrees celsisus? I try to put it above 22 and it will not go??
Other than that, I like the look, the ability to access when I am away from home! But if I can't get it to go above 22, I may need to return it!
I am saying until the bugs are worked out- I wouldn't recommend to buy.

Rated 4.0 out of 5.0 by jw01 Good thermostat
This t-stat works quite well, but it does have a problem with temperature overruns. I set it 2 degrees lower and when it kicks on in the morning it overshoots the temperature, then seems to settle down. One disappointing thing is my wifi is protected and it sometimes loses it's connection and I have to disable my protection to re-establish a connection to the wifi. This is impossible when you are miles away on holiday and you wish to view your home temperature.

I had a quote from the HVAC inspector at my 60 year old home I had just purchased of $900 to install a Carrier system thermostat that would control both the Carrier heating and air conditioning systems. For less than a quarter of that and may be a hour and a half of my time, I installed this thermostat. No problem following the attachment of the colored wires. No problem shutting off the electrical supply to the gas heater, electric air conditioner and air handler. The hardest part may have been trying to remove the old thermostat without breaking it and the wall behind it. When connected the thermostat it readily found my wireless internet connection and set up was easy. It was also easy to change the background color from blue to gray to stand out less against my walls. The program for temperature changes works easily and in the same fashion as the Carrier thermostat in the home I just sold. I am really pleased each day as I walk by the thermostat and get the weather conditions outside and know the thermostat is well installed and doing it myself saved me a significant sum of money.

Rated 4.0 out of 5.0 by badlt Awesome Product!
Just installed this the other day and it works great! Although it requires a "C" wire and my original thermostat only had 4 wires and no "C", there is a simple video on their website on how to connect the device without a "C" wire. Also, you can purchase the Venstar Add-A-Wire module in order to regain independent control of your furnace fan.
The only reason why I am not giving this a 5 star rating is because I had to manually change the DNS settings on my router in order for the thermostat to connect to AccuWeather to show the outside temperature. All you need to do is change the DNS settings in your router to Google's (since they own AccuWeather) Google DNS servers (18.104.22.168 / 22.214.171.124). Once done, your external readings will display after a short time.
Now I just have to repaint the area where the old thermostat was!

Worked well for heat during winter but unable to get the air conditioner to work now. A different thermostat was installed and all works fine. Honeywell is refusing to refund my defective unit that is 5 months old. Honeywell says they will replace but I have to have a technicians report to show that. I don't need it replaced as I had to buy a new one to get the ac working, I need a refund. Not sure where to go from here. Out over $200 from what I thought was a respectable company (Honeywell)

Ok, So I decided to shell out $200 for a new thermostat partly because I have the entire house hard wired for networking and running two servers, and partly because the old battery powered one was acting up. So why not include the HVAC in the network, It was pretty easy to hook up after I realized I had to run a "C" wire to get 24 volts to the thermostat. So now it's online for about a month, So far...so good. My only complaint...during the night it changes color from the default blue to white for about a hour or so then goes back to the selected color profile..Why ???..Is it checking for software updates ???, Is it transmitting data back to honeywell so they can improve the software ???. Does it have spy software in it ???. It is a learning thermostat so is it storing data it gathers on honeywell's servers ???, Got me..but it does seam rather obvious it is doing something in the background. I am waiting for honeywell to respond to this question

This thermostat allows us to program the a/c and heat at the same time. If it gets below the set degrees for heater, it comes on and if it gets above the a/c setting, the a/c comes on automatically. You can change it remotely through Wi-Fi from other locations. The backlit panel is very easy to read and you can choose the color of the light! Our electric bill has been reduced by 20% as well. Cant wait to see how the summer months fare.

Rated 2.0 out of 5.0 by nathanh SOME FLAWS, POOR CUSTOMER SUPPORT
I've had this unit for 8 months. My Outdoor Temperature always shows "Waiting for Update". Customer support was not able to help. The other issue I have is the Indoor Temperature seems to immediately decrease by 3 degrees when my furnace turns on, and immediate increase by 3 degrees when the furnace turns off. I was thinking it is maybe due to the heat generated by the thermostat and airflow from furnace fan. Also, Indoor humidity is off by 10 when compared to multiple other units.
Controlling temperature via Wifi seems to work well though.
