I can't recommend ratgdo (Rage Against the Garage Door Openers) project highly enough. It implements the protocol and allows you to interact with the door: https://paulwieland.github.io/ratgdo/ https://paulwieland.github.io/ratgdo/ The protocol itself is crazy, with obfuscated ternary data (instead of binary). People who reversed it are heroes.
