FreeMDU as Interface for Miele (or BSH) appliances

Hi,
I just received an interesting link to a presentation in Hamburg at the CCC congress

Hajo (BSH appliances) and Severin (Miele) have done some reverse engineering to establish a communication with the proprietary interface.

I have just ordered some parts to build the interface based on a ESP32-C3 and an optical sensor.

Has anybody started as well?
