Bosch heat pump 5800i and Home Assistant

Hello dear Home Assistant community,

a question in advance.

Does anyone have a Bosch 5800i heat pump and Home Assistant running?

I have found several approaches on the internet, but none have worked.

Briefly about my system:
1x Bosch heat pump 5800i indoor and outdoor unit
1x K30 RF module. Values are read out with the HomeCom app.

Hope it worked.

Thanks and greetings
