@blue-bean I marked the dev branch as main branch in my repo. If you want to use those sensors, you can add my repo as a custom repository to HACS in the meantime.

I've tested your files but with this changes i've the effect that every second start of HA there are some sensors missing (only every second restart - after next restart all sensors working fine). Very strange

@blue-bean I've seen similar behaviour, not sure if it's really related to my chances as I see an exception in a different place. Seems to be a timing issue. But I'll have a look.
