For a home with multiple start vents, a vent thermostat platform based on generic_thermostat will be use full to control each vent independently based on the settings of the master thermostat.
This platform will be configurared like this:
climate:
- platform: slave_thermostat
name: Study
cover: cover.study_vent
target_sensor: sensor.study_temp
climate: climate.home_thermostat
This new climate will control the aperture of vent based on the actual operating mode of the master thermostat and the target temperature of the room.
