If I could leave something less than 1 star I wouldn't hesitate to do so. This app is nothing but buggy every time I've used it. I have had nothing but problems with trying to get my thermostat set back up on wifi only for the app to constantly crash regardless of the device being used. I sat for over 3 hours trying to get this app to work for it to not work only to have problem with the ios version for IPhone too! I can't get it set back up and the app won't even launch.
