ratgdo32

Quick verdict

When Chamberlain killed free myQ integrations, ratgdo became the answer. This ESP32 board wires into your garage door opener and gives you full local control over ESPHome or HomeKit, no cloud, no subscription, no asking permission to open your own garage. It reports real door state, controls the light, and handles obstruction sensors. Check the learn button before you order: purple, red or orange (Security+ 1.0) and yellow (Security+ 2.0) both work, but a round white button means Security+ 3.0, which ratgdo cannot talk to.

Standout: An open-source ESP32 board that locally controls Chamberlain/LiftMaster Security+ 1.0 and 2.0 garage openers (not the newer Security+ 3.0) with no cloud or subscription required.

Compatibility snapshot

Why it stands out

• a leading open-source way to get local smart control of the Security+ 1.0 and 2.0 garage openers Chamberlain locked down, plus a dry-contact mode for non-Chamberlain openers
• open-source ESPHome and HomeKit firmware options, no cloud or subscription ever
• reports actual door state (open, closed, opening, closing) plus obstruction sensor, light, and wireless lockout

Reasons to hesitate

• does not work with Security+ 3.0 openers (round white learn button, November 2025 and newer), which carry no wired data line for it to tap
• requires wiring into your garage door opener terminals, not a plug-and-play install
• WiFi-only, needs a stable wireless signal in your garage
• no native Google Home or Alexa support without going through Home Assistant

Best for

• Chamberlain or LiftMaster owners who refuse to pay for myQ cloud access to control their own garage door
• Home Assistant users who want a fully local, zero-cloud garage door integration

Avoid if

• your opener has a round white learn button, which means Security+ 3.0 - ratgdo cannot drive it at all
• you are not comfortable wiring into your garage door opener's terminals
• you need native voice assistant support without Home Assistant in the middle
