not the greatest, pretends to tell you the outside weather but updates seldomly, either daily or weekly. If you set the thermostat to heat your house starting at 8 AM and starts quite a bit before that, supposedly to make sure it's warm when you get up , keep that in mind when setting the thermostat. Not happy with this unit.
Great but occasionally loses signal. Plugged right in to old thermostat plug. Would be better if plug fit through mounting bracket. Had to rewire plug.
I would love this thing if it weren't for 1 issue. No matter how many times I use the app, it acts as though it is the first time and asks me to set it up and set a schedule. I already have it on a schedule. This is mildly infuriating at this point. 3 stars because it does work and works well. The additional sensor is fantastic and accurate. Fix the bug and it's 5 stars easily.
The T9 Smart Thermostat was easy to install and set up. I’ve added four sensors to help monitor other room temperatures. I’m still very new to the use of smart thermostats, but so far it’s working pretty well. I still have yet to try the schedule programming, but that looks easy to set up as well.
