Well, correct me if I’m wrong, but when I replaced my existing standard relay driven garage door opener with the MyQ I tried using the existing relay switch button to wire it to the myQ opener and it refused to work. I needed a special binary coded switch which came with the myQ opener to work. This led me to believe the controller on the MyQ garage door opener doesn’t work with simple relay switches. Hence GoControl’s Linear GD004-Z won’t work as I operates on a principle of a simple relay switch connect activate the garage door opener.
