The set-up worked well after I received the code to activate the app. Creating the flat map was a little more difficult. The device has a bit of trouble with the window front, which reaches down to the floor. Once I had lowered the shutters, it worked perfectly. And with a four-door mirror cabinet, it also had trouble entering the front correctly. The room was shown much larger on the map than it actually is. I will cover the bottom of the mirror cabinet with some newspaper and run the recognition again with the blinds closed and the mirror cabinet covered.
