I highly recommend anyone having problems with this consider trying this free as in speech (and as in beer if you've got solderimg skills and an ESP laying around) solution: RatGDO [0] 40 bucks, HA, and about half an hour each (mostly fiddling with the ESP/shield pcb wiring inside the light cover of the opener from the awkward overhead-on-a-ladder position) for me to no-cloud smartify two chamberlain MyQ openers. Special sauce is that the device can MITM the "Security2.0+" signal and emulate the discrete functions of the wired wall remote, not just act as a dry contact relay on the motor. Result is that separate entities are created not just for the door open(ing)-clos(ing) states, but also for the obstruction sensor and a separate switch to turn the opener's light on or off remotely, all exposed (as MQTT topics) in HA.

I think I have everything needed lying around in spare parts. Know of a guide for install? I tried building something similar years ago but got stuck on the software.

  You may actually need a little bit of extra information to replicate a handful of traces (i.e.on breadbpard) present on the little PCB that the ratgdo software relies on to interface the espressif to the terminals of your opener. It's not terribly complicated but for reasons that are polarizing to many in the garage-door-automation society, the author of the software, although leaving the code completely open source is averse to publishing schematics for the PCB board itself, so others have had to step in and reverse engineer these. It appears that this project has gone from a very minor side hobby an actual business for the author, and the PCB schematics are pretty much the only IP moat he has, without them he's just providing a very easily (and cheaply) replicated PCB assembly service. I believe, although I have not verified because I haven't tried this myself, that this site provides both the schematics you need as well as information necessary to Flash the software onto your ESP device. https://github.com/Kaldek/rat-ratgdo/tree/main https://github.com/Kaldek/rat-ratgdo/tree/main
