Sorry - no one category fits my question.
My thermostat has been installed and worked fine for about 9 months. A couple of months ago it started lighting up when I near it or press on the display, but no info displays. I was still able to control the thermostat using the app. A couple of weeks ago, it started behaving as if the app was controlling it, but either never received the command or it set itself back to the previous state within a few minutes. Now it seems as if the app is not controlling it at all, although when I get into the app settings it says it's connected.
Do I just need to bite the bullet and replace the whole thing? Or is there some exercise for testing it?
