Seems that the Home Assistant user base, as determined by Chamberlain, is relatively small. To hardware/software hackers this type of vendor pull-out/lock-out should always be expected. However, since the end user has physical access to the device thinks like ratgdo[1] will always be an option. While the app integration is nice, garage doors still seem to be one of those things that just needs to work in proximity and a smart phone app and alarm.com / amazon integration are superfluous add-ons.
I bought mine from Costco for the simple reason that I could return it if broke.
Thank you, thank you, thank you. The ratdgo has open source firmware that implements the encrypted serial communications needed to control and get status from Chamberlain / Liftmaster garage doors (without needing the myQ hub).
> It works with virtually any residential Chamberlain or Liftmaster manufactured garage door opener and also offers basic support for other brands which use dry contacts to control the door.
> It can control the door and report back the actual status of the door (closed, opening, open, closing). For Security + 2.0 door openers, the obstruction sensors, light, wireless lockout and even motion sensing are also integrated.
