Very nice and easy to setup and use. Most smart thermostat on the market can be complicated to setup and hard to navigate but not the t9

It was super simple to set up (as long as you are not having to undo the rat’s nest of wires the last owner had). It is super easy to navigate and it is easy to see. It does not have a ton of settings…. Because the settings it has are expertly set up so you don’t need them. The T9 is the best smart thermostat (out of the 9 I have either used or installed) that I have encountered with amazing connectivity, ease of use, and simple to navigate screens. This is a thermostat that will cover every need for 90% of people out there, hands down.

The major disappointment with this thermostat is that it isn't programmable for the temperature differential at which the auxillary heat turns on when installing on a heat pump system. If the temperature schedule varies by more than 2 degrees, the auxillary heat automatically turns on 'wasting' money on trying to heat quickly instead of letting the heat pump do it's job. And one cannot turn this 'feature' off by setting a minimum temperature at which auxillary heat is used. This thermostat would be fine on a gas heater system or if one didn't want to schedule temperature differences more than 1.5 degrees.
No, I would not recommend this to a friend.

I had an older model Honeywell thermostat that based the temperature of the whole house off of one room, and because of the window configuration in my home, that was less than ideal. This new thermostat comes with room sensors and can tailor heating and cooling to active rooms in the house and I LOVE IT.
I would recommend this to a friend!
