App is untested. Got my mysa installed today. After a day if use, you got graphs per unit, one of the graphs is set point. Go to the day before (when mysa was not installed), set point graph remains. Toggle it off , then on. App will crash. This is basically a unchecked null pointer. This app has no unit tests. Also it already lost connection with two units. i am really disappointed, do they cover electrician fees in their return warranty?
