Came with my new Rheem HVAC unit. Doesn't refresh, Where is the outside humidity. Limited information on the screen.
No, I would not recommend this to a friend.

Hi grammytoo, thank you for your review of the T9 Smart Thermostat. You can check the outdoor information on the app. Please make sure that background app refresh is on for the Resideo or First Alert app and feel free to contact us for further assistance.

Not great at accurate temperatures, even checking with industry grade thermometers right next to it. Very disappointed. Cuts on even when below target temperature
The very first dependable Smart Thermostat for all your needs, so simple to use I never need to touch it just access it from my Smart Tv, Mobile Device via Google or Alexa and even Apple Home
