So easy and reliable. I can see current temp on display from across the room. I like how the display changes color when the heat or cool is on. Can adjust temp from anywhere using my phone. I have a office that always is a little warmer in summer so it’s great I can prioritize that room to keep it cool when I’m in there. Best thermostat I ever had.
The hardware is great, really liked the extra device that helps with not having the power wire at the thermostat. The app however needs a little more work, temp does not seem to update after opening unless you go back and forth a few times, also, needs the ability to control humidity (not just get alerts). I was also VERY disappointed you can not have two thermostats to work together to deal with the whole house. I have to separate systems in the house and the thermostats are clueless about each other...yes you can add two to the app, but what good is that if they cannot work together? You are Honeywell, you are better than that, Nest made it work, and you do it on the industrial side...please fix!
Easy setup since I replaced a Honeywell thermostat that had the same wiring base. Pulled the old off & pushed the T9 on. No wiring changes. Setup with the app was easy. Now my heating & cooling is Smart.
