great
at first i was going to return them, but i had a bad c wire. fixed that and this blows away nest. i was on my second round with nest, and that died. i could spend a couple hundred with these or another 1000 for nest. i went with these, integrated with home kit perfectly. so easy to control, they got the geocoding down right, nest never could. they also dont play games with the temp, like nest did. i am so much happier, and i am saving over ring, by almost half. if i had to do it again, i would start with these and saved a lot of money ... show more

Honeywell thermostat
The unit looks brand new. It was easy to install and came with all instructions and hardware. The app is ok. So far so good, its working as expected. It also does the auto changeover so you can set heat at 68 and cool at 73 and it will flip itself back and forth accordingly.

Nice Replacement For Older Unit
It works pretty well. Was an easy install since it was replacing an old Honeywell unit...it just plugged in. Using the app makes setting up schedules much easier than on the device itself. It appears the temperature sensor needs to be calibrated since it is displaying 2° too low compared to 3 other thermometers placed next to it. I wish they would rename the app to "Honeywell" so it matches the name of the unit. In general, a solid purchase. ... show more

Great value
Setting up and connecting to wifi isn’t automatic or very intuitive. But once you figure it out, it works great. Haven’t had a problem for over a year now. A great, less expensive option to nest or google.

Highly recommended!
Great replacement for my existing Honeywell thermostat, I just took off the old “face” and popped this on Sam’s note I can control my climate settings via WiFi! Setup was easy enough, highly recommend!

Decent
Easy to install. Decent interface. The app can be finicky. Biggest complaint is that it seems to turn off as soon as it hits the temperature selected. I feel like any thermostat I’ve had in the past will continue to cool in order to get to the lower end of the selected temperature that way it takes awhile to kick back on. With this it seems like my AC is kicking on and off every few minutes which is super annoying and probably isn’t best for the AC unit. ... show more
