I installed the MyQ retrofit kit to my 10-year old garage door. It included the motion-sensing switch and the hub. I hooked up the switch first and enabled motion sensing to turn the opener light on when motion is detected. It was working perfectly for over a week. Once I paired the switch to the hub, the opener light now comes on randomly. I ended up disabling motion sensing on the switch because the opener light would stay on almost constantly. Any idea what could be wrong?
