[Question] Using dry contact pins to monitor open/close status #319

Closed bradyemerson closed 2 months ago

bradyemerson commented 2 months ago

Hi, I have a basic open/close magnetic sensor attached to the garage door and would like to use the dry contact pins to read the status of the sensor. Is this possible?

Please check the dry contact wiring diagram.

Hi Paul, thanks for the link. On the Security diagram it says that the bottom dry contact pin pulls to ground when the door is closed. If I'm understanding that correctly, I believe that means I can monitor open/close from that pin. I'm looking to do the opposite - - read open / close from an external magnetic sensor.

The use case is if someone opens the door from the emergency handle, I don't believe the opener knows the door is open. But the magnetic sensor would.

Is that interpretation correct?
