I’ve been interested in triggering my Ceiling Fan based on my Furnace Fan activity. Initially I thought I could set the trigger based on the thermostat’s thermostatOperatingState. But after monitoring the Devicee Logs in ST for the past few days, I’ve realized that the fan is triggered more often by the Furnace control board, than by the Thermostat.
Is anyone aware of some kind of ST sensor (i.e. relay) that I could connect to my Furnace control board, that could report that the fan is on or off? I believe the control board’s output is 24vDC, and ideally I wouldn’t have to connect up the 110AC from my house to the sensor.
