Hi Thomas,
I am quite new at Home Assistant, but I have plans to use it in Smart Home installations.
Actually I am installing the next Vaillant system for my client:
- Heat pump aroTHERM VWL 125/5 AS (4000 V) + VWL 127/5 IS split + ekviter. reg.multiMATIC 700
(floor, wall heating and cooling system) - uniSTOR VIH RW 400 for hot water
- heat recovery ventilation recoVAIR VAR 360/4
and VR 920 for external access.
So I will have quite complex Vaillant installation.
I found your project (Vaillant component for HA) as very interesting and I could be able to support some data or test some functionality, if it could help to improve and enhance the componet for example about ventilation and finalize it as some stable version.
Pls let me know if you are still working on it or what are your plans about it.
Thank you.
Peter
