Does anyone know if it’s possible to attach the Garage device to a GDO-11V3 Ero?
When I remove the back of the overhead Garage Door opener there is a panel which has the following connections available.
AUX/OSC OV SB-2 OV SB-1 V+
Is it possible to connect the two wires from the Garaget to any of these connections so that I can operate the garage door remotely from the phone app?

Yes, it’s likely first two: OSC (Open/Stop/Close) and 0V (Zero volt).

If your “Garage device” is a smart relay/controller
Most smart garage kits work by:
- connecting two wires to the **wall button terminals (dry contact)**
- simulating a **press button signal (short circuit momentarily)**
