The Goal is to "MySeonsorize" Light-Switches in a existing building-circurit. Without change the Design and smallest effort as possible.
This Node is build based on a ATmega328p and a NRF24L01-SMD Module.
This enclosure fits for GIRA System 55 switches. And can be adapted for other Vendors. The project is hosted on GitHub, feel free to contribute for other Vendor or Series.
Building:
