This product doesn’t work with the Honeywell app. Misleading to say the least.

did not work without a cwire, so we had to return it

I am returning it to the store. After 5 minutes the screen said it had a defective sensor and needed to be returned to store. Installed it the night before guests were arriving for Christmas, only to have to reinstall the old one.

I had a professional installer hook up the thermostat and nothing. It did not show the slightest signs of turning on. I am hoping that just this one unit was a dud, but I was not willing to find out. I returned the unit and went with my second choice.

Purchased this and returned it after we discovered it didn’t work.

the good: -ease of install/setup - very simple install. instructions clear and easy to follow. -design - compact, stylish touchscreen. -UI design - intuitive, well laid out. indoor/outdoor conditions, color customization for the display, making it easy to match any taste. -wifi connectivity, app control - being able to view and control settings from the app is fantastic the bad: -none that i’ve found so far overall: this thermostat is a replacement for a relatively old 4 wire thermostat in my game room. i was lucky in that the thermostat wire that was run actually included the common wire, though it was not hooked up to the controller board. (there are 2 options for installations with only 4 wires - using the G wire as common, or purchasing a $25 4->5 wire converter.) all i needed to do was connect that wire on both ends (controller board and thermostat) and everything functioned as expected. installation took maybe 15 minutes, and would’ve been shorter if not for the trip into the attic. once everything was up and running, the set up was intuitive and straight forward. one caveat, you do need to register for a honeywell account online to be able to use the app, but not a big deal for most. other than the typical thermostat setup and of course the stylish design, i can now cool off my game room before i go up there, with a click of a button from my phone. awesome!

Looked great, however too difficult to install. After unboxing and reading instructions I was made aware that an additional electrical power supply line was needed to power the unit.

I like that you can change the color of the display

If i could ill not give any star .the tech not professional at at he couldn't install it and insame time ruin my old one so i had to call the heat company to fix what he did and that cost me alot .

Don't buy this thermostat it did not let my heat strips disengage so it run up my power bill 80 kw a day.

Had to bring back. Followed direction ax not heat would work. Had a buddy who is a hvac guy come out and said the thermostat is bad. Would not recommend

The thermostat never stays on. It goes on and off all the time.

It seemed like a good item especially after the power company rebate but it just wasnt compatable with my hvac set up or it was a dud. Just would not power on at all. Had to take back.

I am very happy overall with this thermostat, and have now upgraded myself into the current Century. It is a vast improvement over my older single set thermostat. Setup: Setup for me was fairly painless, and this is coming from someone who isn't DIY enabled in the least. I was lucky though since I was going from Honeywell to Honeywell and I have a more modern Heat Pump that had a C wire. Overall the manual was great and allowed me to understand what I needed to do and kept things simple. Only hard part in the installation was when I docked the unit back. Took a few seconds to come on and boot up. But once it came to life all was well and I'm happy that I was able to do it myself and not screw up. Getting the Unit Online and connected to my network was fairly simple and then getting it setup with the Honeywell Website wasn't bad at all. I appreciate that Honeywell has a Website and an App. Its nice to be able to control the settings and alerts the way I want. Usage: Once I got the unit online and schedule set its been fairly hands off. I do like the fact that in the morning/evening I can glance at the unit (since it resides in the master bedroom) and see the weather. It also shows the humidity in the house. Its a new data point I haven't had before and not sure what use I'd make of it, but nice all the same. I have noticed that the unit does tend to make sure the temperature is at the setting scheduled right when the schedule starts. That's nice because I can set it for my usual wake time and not have to guess do I need an extra 10 minutes to get the house warm in the morning. I also enjoy the fact that it will keep the house between a range, handy for when you get into early fall/spring where its cool in the morning hot during the day. Having to switch back and forth was a pain, its nice it will keep the upstairs comfortable. Only real con I have with the unit is the display is always on. Since it is in the master we have a new nightlight. It does dim and since you can change the color of the unit you can select something that suits the room. I'm very happy with this unit and it seems though out. The schedule you can set has four times, wake, leave, return, sleep. That seems to cover my day and it even has a vacation feature for extra savings when your out. Additionally with the Wi-Fi support I can adjust the temp remotely, or in another room. If you have a thing for Alexa, you can add this to your Alexa skills and change the temp. with your voice, but honestly I like the more set it up and forget it. If you need to update to something more modern this may be the way to go.

The Honeywell Smart color thermostat first of all looks amazing on a wall. It gives a very classy look, more so than other smart thermostats, with plenty of data displayed as you walk by. If you're not fully experienced with installation and are going it alone, MAKE SURE you take a photo of your existing thermostat's configuration in the event this does not work or you need to revert back to the original installation for any reason. The thermostat does require a "C-Wire". DO YOUR RESEARCH on this with your system BEFORE buying this thermostat. The c-wire essentially provides recharging power to the thermostat. Older system may not have one of these. (Note, there are workarounds to this which involve running a new wire or purchasing a transformer to power the device). But again, look at the existing thermostat you have BEFORE purchasing this. When in doubt, get an HVAC expert to come in. The system is constantly learning, and will adjust to your manual settings. For example, if you like it warmer while you're watching TV in the evening (maybe that's the coldest room in the house), the system will learn the approximate times you are in that room & move the temps accordingly. Mine is still learning after several weeks of being installed, so don't get frustrated. The ability to set "comfort times" is nice, in that you can say you want it cooler in night when sleeping (we love to curl up in blankets in a cool room), but don't want to be freezing in the morning when you get into the shower. The system will automatically turn itself on at the right time based on the time you say you want it to be warm (for example, I say I want it to be 72 degrees at 7 a.m.). Again, the system learns how long it takes to heat the house to 72 and will turn on at the appropriate time to give you the 72 degree warmth at 7 a.m. as expected. Adding to the WiFi using the app is easy, and with that can be controlled outside of the house. I can now see when the kids are changing the temps in the house and can set it back if I choose. You can also set it to keep your house at a lower temp while you're out of town (or just while at work), and again have it ready your house to the right temp when you're about to walk back in the door. From a functionality standpoint, it's great. But again, make sure your system will support the device before investing in it. If you're looking at the cost of the device plus the cost of an HVAC tech to wire it up you may want to just stick with what you have.

geek squad couldn't install ended up returning this.

Horrible to set up. Did not connect to my WiFi. Would constantly drop connection! Do not get this!

You won't be able to use the product unless you connect with your wi-fi and a power source, even thou they state that it can be used with or without wifi. Not as described

Couldn’t install it within the return period, just opened it and it’s defective.

Our situation is a little different than most since we're retired. Our schedule around the house is very unpredictable, making 'learning thermostats' pretty useless for us. We did want to add some 'smart home' features, like wifi remote control and alexa integration. And of course, we want a thermostat that will switch between heating and cooling automagically. For comparison, we have a 1900sf ranch style house with two stage forced air heating and two stage air conditioning. This was replacing an older Honeywell thermostat. It took about 20 min including initial setup. Honeywell used the same mounting hole pattern so I didn't even have to drill new anchor holes. The setup was trivial, follow the walk-thru and answer the questions. One note, it is necessary to have a "C" wire (common), so that's something you should check. The unit is very small. It would have been nice if Honeywell had included a wall bezel because it's so much smaller than other thermostats and you may find a small painting job as part of your installation. The thermostat is 'registered' with the honeywell site during the setup process, assuming that wifi is configured. You then create a personal account at the site and link to the thermostat in order to control it. Control is available by web browser, smartphone app, and alexa/google voice. The new display is very clean and the menu system easy and intuitive. It displays the indoor temperature, exterior temperature from a local weather service, setpoint, time, and HAC status. There are menu selections across the top and setpoint up/down arrows. The touchscreen interface works very well. The smartphone app and web interface are particularly nice because our schedule is so irregular. We can set the 'away' setting when we leave and 'resume' on the way home. The alexa interface is pretty comprehensive, you can check the temperature, make it warmer or cooler by some degrees, or set to a fixed temperature. The thermostat works very well with multi-stage HAC, keeping the temperature in a much tighter range while not overcycling and using the lower energy stage setting. One really interesting feature is that the fan can be set to 'circulate' to move the air around when the HAC is off. The fan only will automatically come on about 1/3 of the time the HAC is off to circulate the air and balance the temperature throughout the house.
