This is one of the really old ones with motion sensing, similar to the 398LM that also has compatibility issues. I have not seen many of these out in the wild … it sounds like they were only on the market for a short time and 10+ years ago.
I can’t say for sure, but i strongly suspect it is these much older wall panels that are causing the problem. The 398LM is confirmed known to cause interference with communication, sometimes resulting in unintended door openings.
You can test it by simply removing the wall button from the circuit (disconnecting it). If the GDO blaQ works reliably with the wall button disconnected, then we know it’s the wall button causing interference.
Recommended replacements are the 889LM if you want motion sensing capability and all the bells/whistles or 78LM or generic equivalent if you want a cheaper, basic analog wall button.
I have the same model wall control (41A6318) and have been experiencing random openings/closings as well. I can confirm that selecting +1 is the only protocol option that works - neither +1 with smart panel or +2 work at all. I’ve ordered a 78LM and will confirm here if it solves the issue.
I don’t have the same model wall panel, but I do have an older (purple button) Security+1.0 garage door opener, as well as an old wall panel at one location.
Even before I installed the blaQ, I’d get some random weird experience with the motion sensor on the wall panel, where it wouldn’t trigger the garage light at all.
Anyway, I have alerts setup in HA to let me know if the garage door opens and no one is home, and it kept triggering, and I noticed this in the logs:
The garage door isn’t actually opening, so as a work around, I set a little delay on the alert I have setup. I suspect it’s either a failing wall control panel, and/or the wiring for it, rather than the blaQ itself.
If you’d like to have a look/investigate that particular blaQ, in case it’s some issues with the Security+1.0 protocol implementation, I’d be happy to help. Note that I also had to manually set Security+1.0 and not auto on this one, my other location with a much newer garage door opener supporting Security+2.0 works perfectly, with none of the same issues.
