I really like the approach. Works like a charm. I’ve adjusted the code to my needs (GitHub - bruestel/hcpy: Python tool to talk to Home Connect appliances over the local network (no cloud required)).
You really get all the relevant information about the devices (cleaning required, dishwashing salt soon to be exhausted, etc.). Actually, the openHAB binding would have to be completely revised. Unfortunately I do not have time.
