The problem is the RF remote control! All lamps sets appear to be on the same channel and the remote control - thanks to RF - even going through walls and doors.
What is very inconvenient in neinem case, because I wanted to like 3 shelves in 3 rooms light (on one floor) and no matter what the 3 remotes I use - it always shine all 3 rooms in the splendor of the (admittedly great) LEDs :)
Well, that is one I'll keep the other two go back ...
Unfortunately, there is not the possibility to change the channels. Or I habs overlooked and someone can give me a tip. That would be the dearest to me.
