I love this new thermostat. The air cycling is my favorite feature. The app could use some work (why this is only 4 stars). The geofencing can get the thermostat stuck in an away mode if something happens to your phone (turned off or battery died) while outside of your geofence. Aside from that, I love it.
It's been a huge disappointment! It hasn't helped one bit with the distribution of heat in my house - l now have to use space heaters. l had the T9 professionally installed -- wish l could return it.
Love the option to monitor upstairs room temperatures with the sensors to prioritize heating, as my fireplace turns off my heat to the house. Also glad to have the dimmer settings to use the thermostat as a night light
T9 smart Thermostat is great, we have remote sensors in various rooms throughout the house and it works like a charm. Regulates the temperature well in all the rooms, had it for 2 months now and haven’t had any issues.
