Opengarage is a similar option that comes out of the box ready to go. Also FOSS.

Thanks for this, glanced at the site and I like that it's got a motion sensor built into the unit which is convenient. But I wasn't able to tell from an admittedly cursory glance if the opengarage can decrypt the Security+ 2.0 signal that's on the wire in MyQ devices, or if it's just a dry contact switch replacement which will not work for such devices.

I bought an OpenGarage for my brother maybe 5 years ago (“Black Friday” sale every year). He gave it back to me when he got a new opener. I updated the firmware , installed it on an old opener at our dad’s house and it works great. You might need the “Security 2.0” accessory, or they have instructions for soldering wires into an existing button:

It will do Security+ 2.0 with an add-on module (or that was the case several years ago when I got mine).

The device has been fantastic, I got mine about 4 years ago and I just never think about it, it's never failed to work (even after power outages).

Mine isn't a motion sensor, it's a distance measuring device, it's how it can tell if a car is in the bay or the garage door itself is open (you set the distances in the device)

The description on the OpenThings website is misleading, the add-on module is an off the shelf commerical remote that is being shorted in order to operate the door.

The ratgdo device is decoding the line version of the Security+ 2.0 protocol, which gives you state information/etc. They have a page describing what they currently decode:

FWIW The Flipper Zero can decode the wireless version of the Security+ 2.0 protocol.
