I have 2 units and they were both working fine out of the box.
I face the same issues as the rest of your users such as false alerts (light issues) and too many notifications. Still, I am not worried about them.
Few days back, one of the units stopped sending the RED laser beam. I can still open and close the garage door but now all the notifications are wrong.
The 2nd is still working fine.
Any suggestions on how to fix this?
