How do I reset the zone photos to default?
Currently there is no way to do that in the app. You would either need to delete and re-add your controller or you can PM (click on my name and send message) your username and the zones you want set back to default.
So how do I delete my controller?
That’s three years ago; is there still no way to do this?
Unfortunately, I do not see an easy way to do this (without deleting controller, etc.) either: web, API, or Android app.
