Hi everyone - I’d like to know what device I can add to SmartThings that will tell me when my dehumidifier opens or closes a motorized damper.
Quick background: When it wants fresh air it opens a motorized damper on a duct line, and then after a certain period of time closes the damper. There are two low voltage wires coming from the dehumidifier control board that connect to two wires on the motorized damper. I don’t know how it works, but I assume it puts voltage on the line or takes voltage off the line accordingly.
I would like to wire a smart device into these wires so that I can get notified (using IFTTT) whenever the the damper is opened and to alert me to things such as being opened too long, or too much time having passed without the dehumidifier opening the damper.
Two questions please:
What smart device or devices would you recommend I use to be able to monitor this open/closed state. Note that I cannot do this with vibration or moving parts like the multi sensor since nothing is moving externally (the damper is inside the duct work).
How would the smart device be wired in? Just leave the existing two wires connected as is, but also connect these wires to the smart device?
