My ecobee thermostats have a ventilator control that brings in fresh air. This is not the same as the fan control. Native to the ecobee the only option I can find is minimum run time per hour for the ventilator and free cooling which is supposed to turn the ventilator on when outside air is below the desired indoor temp and cooling is desired but it ends up not turning the ac-cooling on and so I don’t like that. I’d like to be able to turn it on/off at will. I don’t think ecobee will give this control, so I’m thinking about ways to offload the ventilator control from the ecobee to something else. Maybe something from esphome? What do you suggest?
