## What it is
ratgdo is an open-source WiFi control board and firmware for residential Chamberlain/LiftMaster/Merlin garage door openers, including Security+ 2.0 models. It provides local MQTT, ESPHome, and HomeKit control with door status feedback, without any cloud dependency or subscription.

## Use cases
- control my garage door opener locally with home assistant
- integrate chamberlain security+ 2.0 garage door with mqtt
- replace myq cloud subscription with local garage door control
- add garage door status feedback to node-red
- control garage door with apple homekit without a hub
- wire dry contact control to a liftmaster opener
- monitor whether my garage door is open or closed locally

## When to choose
- you have a Chamberlain/LiftMaster/Merlin opener, especially a Security+ 2.0 'yellow learn button' model that resists dry-contact relays
- you want fully local control and status feedback with no cloud or subscription
- you use Home Assistant, ESPHome, HomeKit, or NodeRED and want direct integration
- you also want obstruction sensors, light control, and motion sensing on supported openers

## When to avoid
- you need a purely software solution without wiring a physical board to the opener
- your opener is a commercial model or an unsupported brand with neither Security+ nor dry-contact terminals
- you prefer cloud-based control from outside the network without setting up remote access yourself
- you are unwilling to solder or wire terminals on your garage door opener
