Shelly Plus Uni wiring diagram

How it's wired, terminal by terminal

1. Pulse a garage door opener

   Dry contact to the opener's trigger input

   The Uni runs off the motor's own 12 or 24 V accessory supply on its red and black leads, so no mains goes near it. The two OUT1 screws close briefly across the motor's pushbutton terminals, either way round. In the Shelly app, turn on Auto off for the output with a short delay.
