Secplus GDO is an ESPHome component for controlling Security+ and Security+ 2.0 garage openers made by Chamberlain Group, including garage door openers sold since 1997 under the Chamberlain, LiftMaster, Craftsman and Merlin brands.
Adapted from RATGDO and Secplus GDO
The ratgdo and secplus developers found a way to communicate with Security+ garage door openers over a reverse-engineered serial wireline and RF protocols. This novel development enabled owners of Security+ garage openers to read and send commands directly to the garage unit. At Gelidus we are seeking to reverse engineer the MyQ smart controllers further and develop RF based controllers.
