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.
