no…just no! I refuse to succumb to the sad place I retreated to after the 2016 fail - that is not our future, that is not going to happen! I can not let myself imagine this future and you shouldn’t either.

Don’t sweat the RAM. The M series really are different than the intel forebears. You’ll be fine with all of your considered options.

The cheap-as-dirt meross does, it has an open/closed sensor.

Most openers have a dumb switch interface. A simple close-to-change circuit - I’ve never had one that wasn’t that way. If MyQ is so complicated (serial interface!?) then it needs to go anyway.

lol, just get a dumb opener and a shelly relay or use a meross unit. Super cheap and flawless local control that is cloud-connected if you want it.
