My thermostats were installed months ago and could not be connected to the app because they weren’t compatible with the app. An update was finally done and they work great!
It does all I want. The features are very simple to understand. I guess it needs a bit more colors on the screen. It would have been much more "new generation"
It was very difficult to download the app onto my cell phone. Later I found out that the "activity history" was not what I though it should be. I was wanting a minute by minute, day by day history of when the AC was running. The activity history is just a way for the app to communicate that there is a problem with the system.
