ValueError: 'unavailable' is not a valid HVACMode

We need to check the state is in a HVACMode. I think the following change should solve the problem.

UPDATE: Doesn't work with HA StrEnum!

if old_state.state in HVACMode:
self._attr_hvac_mode = old_state.state

This should work:

if old_state.state in [mode.value for mode in HVACMode]:
    self._attr_hvac_mode = old_state.state

Maybe we need to do the same with HVACAction.
