The smart wireless button provides two channels that can distinguish between a long and a short button press. This enables, for example, light sources to be switched on or off or the eco mode for radiators to be activated or deactivated. The flatter design is made possible by the use of two LR44 button cells, which, despite their smaller size, can provide enough energy for up to three years of use (typ.). Installation is as easy as usual with double-sided adhesive strips in almost any location, for example right next to the bed to activate the protection mode in the house and to switch off several lights when going to sleep.
