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!

Easy to install and works perfectly. I never lost the connection. Even when I lose power, it reestablish the connection by itself once the power is back on and it keeps running the schedule normally. I think the people with connection issues might have a problem with their WI-FI settings and not with the thermostat. The smartphone and tablet app works perfectly without any issues. The app is very convenient and a money saver.
I have it for almost a year know and it still working sharp.

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.

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.

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 2.0 out of 5.0 by Tom3 Not for those who value privacy
This is not at all what I expected from a "Wi-Fi" thermostat. The thermostat does connect to my Wi-Fi network and I can control it from any internet connected computer or device. There are even apps for Android and iPhone, but it is not directly accessible through my local network. The only way to access the thermostat is through Honeywell's Total Connect Comfort website. There are a number of drawbacks to this setup.
1) If the internet connection the thermostat uses to connect goes down, which happens from time to time, I lose all remote control of the thermostat. If I have the thermostat installed in my living room and my internet goes down, but my local Wi-Fi network is still operational I cannot remotely control the thermostat from let's say my bedroom by directly accessing the thermstat via it's local IP address.
2) Because the thermostat communicates with Honeywell it sends usage information to Honeywellat least every time I log into the system and likely more often. After setting up Wi-Fi on thethermostat I was surprised I didn't have to make any changes to the firewall settings on my router. I try to keep my network locked down as much as possible so there would be no way forHoneywell's system to access a device on my network unless I specifically granted those rights. All devices within my network have access to browse the web. I looked at the logs on my router and it seems that the thermostat is communicating with Honeywell's servers every 12 seconds.
I don't have the ability to monitor the wi-fi packets but at the very least it would have to send current temperature, the temperature the thermostat is set to and any changes that might have been made to the schedule. It will receive any schedule changes, program changes and software updates automatically.
Reading their Terms of Service it seems they keep the usage information received from thethermostat. This can be used to enhance their products and services as well as to help develop new products. I'm not very comfortable with this whole thing. It may not seem like a big deal but giving a third party (Honeywell and whoever they choose to share the information with) access to the temperature in my home and what I set my thermstat to 120 times a day is not something I'm Totally Comfortable with. Let's say someone manages to hack Honeywell's webservers and gets access to all users data. They could look at the usage statistics to determine when people are not at home and even be able to guess when they might be away for an extended period of time. The website uses SSL and I'm told that the communication between the thermostat and Honeywell is also via secure sockets but all systems have vulnerabilities and I don't think it's worth giving up so much personal information for the ability to remotely control a thermostat.
3) The remote control of the thermostat only works as long as Honeywell decides to keep their webservers up and running. If for any reason they decide to stop paying for the internet connectivity and computers required to run the service the wi-fi capabilities of the thermostatdon't exist. There is no way to directly access the device to send control commands or to even monitor the current temperature. According to their ToS Honeywell also reserves the right to start charging a fee for the Total Control Comfort service. They may not ever choose to do so, the usage statistics they get from the thermostats in themselves are a valuable commodity in and of themselves, but that is something to consider. Currently the system doesn't offer much value to the consumer other than the ability to remotely control the thermostat and receive alerts.
I was hoping I could write a few scripts to grab usage information from the thermostat myself so that I can create my own usage reports but that does not seem to be possible. I contactedHoneywell to see if there was some undocumented port I could connect to and was informed there wasn't. I also ran port scans on the thermostat and found no open ports. It appears that at some point that functionality to monitor usage trends will be available through Total Control Comfort but I currently do not see it.
The process of connecting the thermostat to your wi-fi network first requires you to connect a wi-fi enabled computer to the thermostat's wi-fi network. You then direct a web browser to thethermostat and provide the settings for your wi-fi network. So the processing power of the thermostat seems to be pretty good and it already has a built in webserver and it does manage to gather usage information to send to Honeywell. Honeywell just choses not to let you have access to it unless they have access to it as well. This locks you into their Total Control System which I don't think is good for the consumer.
The correct way to do it would be to allow for direct access over the local Wi-Fi network so that you could monitor and access the thermostat without going through Total Control Comfort but still have an option to sign up to Total Control Comfort if you'd like to make remote monitoring easier. I'm sure there would be plenty of people that would use the service because it makes it easier than trying to set things up themselves. The system can send out alerts for example if the temperature at the thermostat rises or falls below a predefined limit and when they do get their analytics put into the system it can be beneficial for those that don't want to come up with their own way of doing it.
As far as the non wi-fi parts of the thermostat I haven't had enough time to give them a good workout but they appear to have the same features as another Honeywell programmablethermostat I have. One of my favorite features that is included in this thermostat is the ability for the thermostat to learn how long it takes your home to heat up and makes appropriate adjustments. So you set it to turn up the heat to 70deg at 6:am if you wake up at 6:00am and thethermostat will turn on before 6:am so it's 70deg when you wake up. They're good thermostats and I'm sure this one will be similar but I don't like the way they decided to go with their "wi-fi".I'll leave the other functions of the thermstat for others as this review is getting long.
Also note that this thermostat requires a "C" wire to be connected. The C-wire provides 24vac current to power the thermostat. It's not powered by batteries but there is a battery in thethermostat as a backup to save settings. Without the C wire the thermostat will not work. My oldthermostat did not have a C wire connected but luckily I had a third, unused wire running up to it. I tried connecting the C wire to the transformer on my boiler but it didn't work. It turns out there's a break in my wire and I had to run a new wire from the thermostat to the boiler but in trying to figure out what the problem was I contacted the manufacturer of my boiler. They told me they don't recommend running a "power stealing" thermostat like this off of the 24vac transformer on the boiler. I chose to buy a separate 24vac transformer that I would plug into a wall outlet to connect to the thermostat. It's possible to do this but it's not documented in the manual. I had to contact Honeywell support to get the recommended connection methods. Please be advised of this if your thermostat does not already have a C wire powering it. If you can't fish wires through walls yourself and aren't comfortable messing with the electrical on your HVAC you'll need to hire someone to do it if you don't already have a C wire. Otherwise the installation is pretty simple.
This is a good thermostat with horrible Wi-Fi features. I know these days we give out a lot of personal information to other people but I don't think it's appropriate in this case. The honeywellthermostats are great if you want a really good programmable thermostat. I wouldn't recommend this wi-fi model for the privacy concerns and the inability to use the remote features if Honeywelldecides to shut down or start charging for their service.
