This repository is a solution to replace the Dobiss master module that forms the heart of the domotics system, with a Raspberry pi.

It has a hardware component to drive communicate with the lighting buttons. This hardware component consists of a Raspberry Pi Pico and some electronics components to drive the Parasitic One Wire bus. The communication with the dimmer and relay modules of Dobiss uses the CAN-bus protocol. I made use of the "SH-C30A DSD TECH USB to CAN Bus Adapter" from Amazon.

The project has also a software component, to achieve similar flexibility in the configuration of the lighting switches as the original Dobiss modules.
