Love the T9. Added two room sensors. Good versatility. Works with Alexa but fell out of schedule mode and switched to manusl when I tried it. Just stick to the Honeywell app.
Easy to install, very user friendly, I like the geofencing feature and the additional sensors that can be added to average the temperature in all the rooms.
This has been quite literally the best thing I've purchased in years! We have problems keeping our upstairs cool and downstairs warm. The sensors help us balance those rooms and keep it comfortable. I don't need a "learning" thermostat. I just need to know when I set a temp, that it is that temp CLOSE TO ME not in the other room.
I thought the sensors that you put in the room we’re going to help adjust the temperature with the heater but it just tells you the temperature. It’s OK nothing special
