After updating home assistant to the latest version the cover.set_tilt_position seems to be no longer valid for the HMIO-BBL actor from Homematic. I’m uisng the ‘old’ CCU integration. Could this be fixed again in a future release?
The same issue occurs for HmIP-FBL blinds. The bug was introduced in 2022.2.0 so for now you could perhaps rollback to 2021.12 to make it run again.
I have opened an issue in the Home Assistant repository with further information to address this: Homematic HmIP-FBL tilt stopped working from 2022.2 · Issue #70218 · home-assistant/core · GitHub
