Heres diy way. you get a $20 ac zwave plug and normally open dry contact relay $10. Use the two wires that run to the wall switch inside the garage that opens the door. Plug the wires into normally open screws on the relay. Hook up to ring app same way. $30. Once the relay is hooked up, plug relay into z-wave plug. Add z-wave to ring app (see next pic) and rename to garage door opener. Done. click the icon plug powers, trips relay, acts like you pushed buttons on garage wall. click it again and it closes the door. wireless and from anywhere. I have both. did the expensive one first and thought of a way to do it cheaper.
