The wireless wall switch integrates perfectly into your existing home installation. Thanks to its battery operation and wireless communication, it can be placed flexibly. Stick or screw your switch wherever you want it. Conveniently accessible by the bed or next to your favorite spot on the couch. In conjunction with the Homematic central unit CCU, it additionally offers AES-authenticated communication, an advanced battery management system, and a configurable button press duration. HomeMatic impresses with its exclusive design, innovative technology, and a concept that leaves little to be desired. It is particularly easy and intuitive to use and can be retrofitted and expanded at any time - simply via plug & play. As a wireless system or wired home control, HomeMatic connects both worlds. It can be easily disassembled and taken along when moving, communicates via BidCos - a bidirectional wireless protocol specifically developed for the needs of home automation - and keeps you updated on the status of individual devices in the house.
