Battery-powered DuoFern single-channel wall switch for controlling shutters The DuoFern wall switch is as easy to install as it is to use. It can be installed in just a few steps by simply screwing or sticking it in place (mounting plate and adhesive strip included). Up to 16 DuoFern devices can be assigned and controlled together. The devices communicate via radio waves - without any other components. In addition, connection to HomePilot® is possible. This makes the switch into a smart home switch and provides additional customised control options - for example by activating scenes. The wall switch is perfect for controlling shutters and blinds, which can be controlled together after they have been registered for the switch - they form a group. It can control the devices in a single product group, for example the DuoFern belt winder, DuoFern Troll Comfort or the DuoFern radio-controlled tubular motor. Functions / compatibility: - Can be connected to HomePilot® - control via app possib
