Problems solved:
- The error when trying to change status indicator or zone in the homey mobile app is a bug in homey 10.0.2 probably. When you first add a note at the botttom of the device property screen, you can save all the changes:device-should-be-string
- Not being able to install new device from ZATZ app: I tried to install the same device twice (in order to get two different statuslines). YOU CANNOT install the same device twice!!
Thanks Stefan
