Trying to configure a climate control automation with Flair Smart Vents

Is 'compCool1,fan' a single attribute value or two possible values?

For your comparisons, the operators need to be within the curly brackets, otherwise you’re just creating weird strings:

value_template: >-
  {{ states('sensor.office_temperature')|round(0, 'ceil') >=
  states('sensor.living_room_temperature')|round(0, 'ceil') }}

Why don’t your Choose options or whiles have conditions?
