Chamberlain / LiftMaster / Merlin garage door openers (Security+ 1.0 and 2.0)

In 2023 Chamberlain blocked third-party access to myQ, breaking Home Assistant and Homebridge control. Paul Wieland’s ratgdo board restores local control with full status over MQTT, ESPHome or HomeKit. No cloud and no subscription; the myQ app can keep running.
- ai
- No AI involvement documented. The project predates coding agents (2022) and credits its human contributors.
- caveats
- Needs a small board wired to the opener's terminals: follow the wiring docs, and it may affect the opener warranty. The board is a purchase (about $45 as a kit) or a DIY build. Check the compatibility docs for your opener.
- evidence
- Public firmware and open hardware.
