I had two linear GDOOZ-4 garage door openers they worked ok but if you break the tilt sensor you can not buy another one. You can pair another old one to the unit though if you can find one.
The tilt sensors are also battery powered so you will have to change batteries every year or so.
They also have a 30 second warning before activating which maybe to code but was annoying and delayed activation.
I changed mine out with the mimolite and magnetic door sensors as I also wanted to get away from battery devices.
modified code works fine
