Communication with other components is performed via the Homematic (HmIP)
radio protocol. Radio transmission is realised on a non-exclusive transmission path;
thus, interference cannot be completely excluded. Interference can be caused e. g.
by switching processes, electric motors or defective electric appliances.
The range inside buildings can be strongly different from the range in open
air.
