Error setting up dual_smart_thermostat at boot

[override80]

Hi!

The integration is working perfectly, but at boot I have this error logged by home assistant:

2022-04-07 10:40:35 ERROR (MainThread) [homeassistant.components.climate] Error while setting up dual_smart_thermostat platform for climate

    return [mstr.lower() for mstr in instr]
AttributeError: 'NoneType' object has no attribute 'lower'

Could it be due to the fact that some entities are not yet available (e.g. heater, target_sensor or openings)? Is thre any workaround?

Thanks!

Hi @swingerman I'm still seeing this in the latest version, is it supposed to be fixed? Can I provide any additional detail?

[swingerman]

This should be fixed by now. Could you please paste your yaml of the thermostat?

Of course, here it is! I tried also commenting out initial_hvac_mode, nothing changed:
