External venetian blinds can be controlled by radio. With radio remote control, a radio signal is sent from the transmitter to the receiver located in the venetian blind. This receiver controls the drive responsible for raising and lowering the external venetian blind or turning the slats into the desired position. Radio remote control offers the major advantages that no cable needs to be routed and the external venetian blinds can be controlled from far away. A central control unit for several units is also possible if they all have a corresponding receiver. Various kinds of radio remote controls are available for external venetian blinds to enable manual operation or operation via a wall-mounted transmitter or Smart Home solutions, which can also be controlled online. Manufacturers like WAREMA also offer programmable functions, including automatic control for the venetian blinds at certain times of the day or when certain weather conditions arise.
