Hi, I just received my Garadget in the mail and everything was going smoothly in the setup process until I got to wiring. I located the two ports I need to plug into (on the left) by tracing the wires back to the door opener on the wall. When I go to share the wires with the existing, nothing works upon restoring power. Neither the button on the wall nor the Garadget app works. I confirmed both the LiftMaster and Garadget have power upon restoring power.
Once I disconnect the Garadget ends to the LiftMaster, LiftMaster works again. I tried twisting the LiftMaster wires around each lead on the Garadget to no avail.
I’m stuck and not sure how to proceed. Help!
