Fix PowerView cover crash when shade position is unavailable #171471

I have Hunter Douglas gen 2 Plantation Shutters. Since the update included in 2026.5.4 my devices and entities are now all Unavailable. The scenes still work. Did this change factor in Plantation Shutters?

@frenck @edenhaus Hello, I am trying to get my Powerview plantation shutter entities to be available again. Can you please advise if that's possible or do i need to roll back from 2026.5.4

How Do find the previous version that broke my Powerview entities. The file is called homeassistant/components/hunterdouglas_powerview/cover.py

I want to manually replace the current file to restore my Entities.

Hopefully this is resolved soon.

Please read this and this.
