Liftmaster hates this one simple trick! Security+ 3.0? HACKED! (OK not really).

I had a spare remote and have wired it up to two relays powered by #esphome so I can open my garage doors in #homeassistant without the stupid myq cloud crap

My house. My hardware. My way! As it should be.

Also, yay. Go Artemis II !

I did something similar with my setup.. Though I dropped the coin battery and powered it from my ESP

@rune that will be my next iteration! I had the sonoffSV on hand so used them for this prototype but they're not the best device for this application (plus they are huge).

V2 will use a couple of PhotoMOS solid state relays instead plus a small buck converter to power the clicker mounted to a perf board.

I put my project box near the exit of my garage, and put buttons on it. That allows me to open/close easily when leaving or at the door end of the garage. Pro tip: look up interlocking the relays so it can't press both at the same time. In my case, the remote couldn't handle that case.

@rune I wonder if esphome can handle that?
