It does everything I want it to do! I can change the temperature remotely. It has a vacation mode that lets me set a high and low temperature for AC and heating functions.
Be sure to remove all factory settings first. Had a difficult time getting the a/c system to work properly after the thermostat install. Even the installer had a time figuring out the problems.
It was a huge pain in the rear to get it connected to the WiFi and now it loses connection every single dang day. So frustrating. The WiFi signal in our house is amazing as we have three signal boxes to make sure it reaches out to our shop and this device inside the house never stays connected.
Even after getting help from the installing contractor, I could not get the T6 Pro Smart Thermostat to connect with the Home app on my iPhone. I gave up and replaced it with a Nest thermostat, which connected easily and works beautifully.
