Rated 1.0 out of 5.0 by Ziggy78 Cycles on and off WAY too often and there is no setting to change it.
I bought this specifically for the WiFi capability. I had a Braeburn digital thermostat that worked great, had a differential of 1 degree. If I set it to 70, once it reached 69 the heat would kick on and shut off at 71. Of course depending on the temperature outside the time it would take to come back on would vary. This thing has my furnace kick on, heat up run for 2 minutes and cool down, hold for about 4 minutes and start over again. ALL DAY. It's a common problem with Honeywell and there is no way to change the setting that they claim to be a half degree. It seems more like a 1/10 of a degree. My parents have the same thermostat basically, but just without the WiFi capability in their house. My house is 50 years old theirs is 3 years old and it does the same thing.
I called Honeywell...... 20 minutes on hold, I had to be transferred over to the "thermostat department" and hold another 20 minutes and got a woman who spoke terrible English, who was pretty much talking to me as if I have never turned a screw in my life. Their customer service is a joke. I hung up after she told me my insulation needed to be replaced.
My old one worked like a charm, I just wanted the WiFi capability. My house is VERY well insulated, this thing is just EXTREMELY sensitive and will wear out any furnace and isn't going to save anybody any money. It's not near a door, or near a register blowing on it when the furnace is running... I figured out on my own there is a CPH (cycles per hour) setting that can be changed, which makes it run a little less, but still doesn't operate like a quality thermostat should. The WiFi and phone app are the only things that work like they should. I'm going to keep toying with the CPH and see how that works out during the summer with the A/C but I'm already predicting I am going to get myself a Emerson (White Rogers) Sensi.
Really disappointed in Honeywell. I've read this same problem in many reviews in many of their digital thermostats. One more small feature added, making the user able to change the sensitivity to a full degree or two instead of a half (I think its even less than half) would make this thing great!

Rated 4.0 out of 5.0 by GeekGuy Great thermostat, poor notifications
I bought 4 of these for the house (should have bought one more). They were very easy to install. One of the downfalls is that they don't have their own webserver, which means that you have to use the Honeywell service to control them. The service is free, but I wonder what happens if they ever go out of business. In addition, because the thermostats connect to the wireless network, I felt it necessary to set up a subnet so that the devices didn't have access to all my personal information.
The one downfall (besides the fact that they don't have their own webserver) is that the alert messages are not customizable, and they are too long to be sent via the text messaging. The alerts work fine with e-mail.

Rated 5.0 out of 5.0 by Happy Great Addition to Our Winter Vacation Home
For years we've been driving up to our vacation home in Truckee at North Shore, Lake Tahoe, CA and in the winter the house was cold and took forever to warm up. Now I set the thermostat to the warm temperature that we like before we leave and when we arrive the house is toasty warm.
Easy to install with good instructions and great on-line video. Once installed, super easy to program and set up the wi-fi account. So far it has worked flawlessly.
After much research I selected this model because I wanted touch screen but didn't need all the bells and whistles of the $200+ models.
I am recommending this wi-fi thermostat to all my mountain friends.

Rated 5.0 out of 5.0 by fstbas Smart Thermostat
Easy to install and setup, application allows remote control from smartphone or any internet connected computer. Can log on to system while at work and check/adjust temperature in house. Needless to say, also great when you have left on vacation and forgot to set the thermostat to a vacation setting.

Rated 3.0 out of 5.0 by abonfietti Ok with conditions
So, it works as expected. It is wifi and installation is easy. However, some basic things to be aware:
- it doesn't have a cool/warm auto function. It is either/or.
- The display remains on at all times (or at least I have not figured out a way to turn it off)
- The auto program only give you 4 on/off periods: wake, leave, return and sleep. So, if you happen to be one of those lucky people that can have lunch at home, you can't program your house to be cool for that hour during the day.
Summary: It is good and the wifi works as expected. I believe the app needs improvement. It is a bit expensive for the conditions you have to accept in my opinion

Rated 5.0 out of 5.0 by Doresoom Best option out there!
This thermostat has all the bells and whistles! I got it as a replacement for my old mercury switch thermostat, and it's quite the upgrade.
Installation couldn't have been easier. It only took 45 minutes from the time I took the thermostat out of the box to the time I had it installed and running my HVAC system. That includes reading very carefully over the directions, cutting power to the HVAC system, uninstalling the old thermostat, and reinstalling this one. Setting up the Wi-Fi connection only took another 15 - 20 minutes.
The included installation guide (which is also easy to find on the manufacturer's website) gives detailed instructions for every step, and comes with peel-and-stick wire labels to make the process easier. Don't just go by wire color - make sure you label them how your old system was set up! There are two separate wiring methods for conventional HVAC systems and heat pump systems. Make sure you know which system you have before you wire it up. I didn't have any problems making all the connections for my heat pump. You'll also have to set up all the options your system has with the touch screen interface as well - such as auxiliary heat, 2-stage cooling, etc. The directions are pretty straightforward for this part too. The only snag you might hit is if your system doesn't have a "C" wire for power. There are workarounds, but I didn't need to try them since I already had a "C" wire for my previous thermostat.
I did most of the Wi-Fi setup with my smartphone. (The directions say you can use a smartphone, tablet, or computer, but I already had my phone with me.) The thermostat produces its own ad-hoc network which you connect to with your device. Then you identify your home Wi-Fi network and login. It's that simple! For control over the web, I created an account on the manufacturer's website and specified the MAC address and CRC for my thermostat.
- The touchscreen display is really responsive. The backlight option is selectable as well.
- The thermostat allows you to set reminders for air filter replacement at intervals of your choice. It also logs the actual system run time, so you'll know you're not unnecessarily replacing air filters that are still good.
- The smartphone app is simple and easy to use. It really encourages laziness though. I've changed the temperature from the couch or in while in bed several times already.
- The web interface allows you to set the schedule a little more easily than on the actual thermostat display.
- The thermostat "learns" your HVAC system and will start heating/cooling early enough to get your house to the right temperature on time according to the schedule.
-The only downside is the relatively loud 'click' the thermostat makes when it cycles the air on. It's not really any louder than the sound of the HVAC system sucking the air filter against the cold-air return, but for some reason it's more noticeable. Maybe I'll get used to it.
I can't say enough good things about this thermostat. If I ever move, I'd seriously contemplate taking it with me. Either that, or I'll have to buy a new one!

Rated 5.0 out of 5.0 by JPKelly GREAT WIFI Thermostat BUT not a WINK controllable unit!!!
Installs and sets-up like a dream. Very intuitive setup and operation and it has a GREAT (free) app to control it. However, FYI - this unit will NOT join up with the WINK HUB. Just off the phone with rep from Honeywell who confirmed it. You won't find the crucial step of selecting "rf10" in the Honeywell menu and thus it can't be added to the WINK. Rep says you must get the Z-Wave unit instead.

Rated 3.0 out of 5.0 by Tony Nice features when it works
I had little troubel setting up the thermostat and it worked fine for two weeks, then it went down hill from there. It seems that honeywell is having system problems and they cant seem to get it fixed. When you go on line or through your smart phone to change the setting, it will change for a few minutes then it reverts back to the system schedule. This happens even though the next scheduled set time has not been reached. I have called Honeywell a number of time and they tell me they are working on the problem. It has been over 4 weeks and still no correction in sight. I am getting ready to return it and purchase another wi-fi thermostat from a different company. When it worked it was good. What is up Honeywell.
