Attribute hass is None for <entity unknown.unknown=unknown> #139945Closed as not planned
Description
The problem
Since version core-2025.3.0 my evohome integration isn't starting anymore. Until this version it worked without any issues.
I've enabled debug logging for this integration. The first error that appears in my log:
Error while setting up evohome platform for climate: Attribute hass is None for <entity unknown.unknown=unknown>
And a few minutes later:
Unexpected error fetching evohome_coordinator data
Details can be found in the additional information field.
