Installing ratgdo

Ratgdo (Rage Against The Garage Door Openers), is an OpenSource project that allows one to interface with the obfuscated protocol that the “smart” Chamberlain garage door openers are using instead of good old dry contacts interface. Ratgdo can also provide the said dry contact interface for your projects, or to provide remote capability to good old “dumb” garage door openers.
