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.
