I bought a used NuTone NGD00Z garage door opener, and I think “used” may be my problem. Basically, I followed the instructions and also the various advice offered on this forum but no matter what I do, I can’t get the ST hub to find it.
I did put the battery into the tilt sensor and sat it within a few feet of the opener.
Basically, when I push the link button, the red LED blinks twice rapidly, waits, blinks twice rapidly again, and on for a bit before it beeps and stops.
I have two thoughts:
Perhaps, since it was used, it needs a reset? If so I can’t find any way to do that.
I have another garage door tilt sensor already in use on the garage door. Perhaps this is confusing it?
Suggestions greatly appreciated, thank you!
UPDATE: for what its worth, from the back of the unit:
