GD00Z-4 Replacement Tilt Sensor

My sensor fell off the door as I used the supplied tape and of course it rolls under the car with no knowledge and gets rolled over.

How can I get a replacement?

Did you ever get an answer to this? I’ve had basically the same problem. I contacted the manufacturer and they were unhelpful. Wouldn’t even sell me a new one.

In the same boat here. I forgot about it and left it attached to the door in my old house.

might be too late now. purchase a new one online, white, about twenty bucks on e bay. install new sensor on garage door. press and hold small button for 7 seconds until you here the beep. change the orientation of the door. if its closed, open it. keep your eye on the gd00z. the light will flash if it adds correctly.
disclaimer: i was able to delete my old tilt sensor first and dont use smart things rather adc alarm system. hope this helps someone
