Have an odd thought and question…this device manages the air exchanger in the house. I switches speeds by simply hitting the button to switch modes. When netatmo tells my our co2 level is too high I wak over and hit it to high to pull in fresher air and push out the bad. Maybe I can use the furnace fan for this instead?
Alternately, I thiught maybe there would be some zwave device I could stick in there. A mini relay of some type? No? Because then I would just be able to cycle it from a smart app. Anyone have ideas on this?
