Just picked up a used GD00z garage door controll that supposedly works 100%. I plug it it, light flashes, beeps, it’s not dead. Go to ST app and try to discover devices, press discovery button on the unit, bit it never sees it.
Thank you both for the reply. I actually did do the exclude twice before I posted, when in exclude mode, I’d hit the sync button on the device and it would just keep waiting and not exclude it. To humor your replies, I did it a third time… and it worked ¯_(ツ)_/¯.
