ratgdo32 disco — Garage Door Controller

Control a ratgdo32 disco (HomeKit firmware) garage door opener via its local REST API.

Security Model

The ratgdo32 disco uses a local network trust model. The device's web API is only accessible from your LAN — it does not expose any ports to the internet and has no cloud dependency.

Your responsibilities: - Keep the device on a trusted, password-protected network (WPA2/WPA3) - Do not port-forward the device's HTTP port to the internet - Use your router's client isolation or VLAN features if you want extra segmentation - The agent should always confirm door state before acting (built into the helper script)

This is the same trust model used by most local smart home devices (Hue bridges, Shelly relays, ESPHome, etc.).

Setup

Set the RATGDO_HOST environment variable to your device's IP or mDNS hostname:

export RATGDO_HOST="192.168.1.XXX"  # or your-device.local

If unset, the helper script defaults to 192.168.1.XXX — you must update it.

Find your device IP via your router's DHCP table, or use mDNS:

dns-sd -B _hap._tcp  # Browse HomeKit devices

Device Info

Configure these for your setup:

Field How to Find
IP Router DHCP table or mDNS browse
mDNS Usually Garage-Door-XXXXXX.local (based on MAC)
MAC Printed on the ratgdo32 board or in your router's client list
Protocol Check your garage opener's learn button color (yellow = Security+ 2.0, purple = Security+ 1.0)
Web UI http://<your-ip>/

Quick Reference

Action Command
Get full status curl -s http://$RATGDO_HOST/status.json
Open door curl -s -X POST -F "garageDoorState=1" http://$RATGDO_HOST/setgdo
Close door curl -s -X POST -F "garageDoorState=0" http://$RATGDO_HOST/setgdo
Light on curl -s -X POST -F "garageLightOn=1" http://$RATGDO_HOST/setgdo
Light off curl -s -X POST -F "garageLightOn=0" http://$RATGDO_HOST/setgdo
Disable remotes curl -s -X POST -F "garageLockState=1" http://$RATGDO_HOST/setgdo
Enable remotes curl -s -X POST -F "garageLockState=0" http://$RATGDO_HOST/setgdo

Status API

GET http://<host>/status.json returns JSON:

{
  "garageDoorState": "open|closed|opening|closing|stopped",
  "garageLightOn": true|false,
  "garageObstructed": true|false,
  "garageLockState": "locked|unlocked",
  "vehicleState": "present|absent|arriving|departing",
  "vehicleDistance": 42,
  "motionDetected": true|false
}

Key fields

  • garageDoorState — current door position
  • garageLightOn — ceiling light status
  • garageObstructed — safety sensor triggered (do NOT close if true)
  • garageLockState — "locked" means physical remotes are disabled
  • vehicleState — laser sensor detects parked car
  • vehicleDistance — distance to vehicle in cm (laser)
  • motionDetected — PIR motion sensor

Control API

POST http://<host>/setgdo with form data:

Field Values Effect
garageDoorState 1 = open, 0 = close Opens or closes the door
garageLightOn 1 = on, 0 = off Toggles ceiling light
garageLockState 1 = lock, 0 = unlock Disables/enables physical remotes

Safety Rules

  1. Never close the door if garageObstructed is true. Report the obstruction and stop.
  2. Always check status before opening/closing to confirm current state and avoid unnecessary operations.
  3. Confirm with the user before disabling remotes — this temporarily locks out all physical remotes (wall button, car remotes). Re-enable with garageLockState=0.

Helper Script

Use scripts/garage.sh for common operations:

# Status (human-readable)
bash scripts/garage.sh status

# Control
bash scripts/garage.sh open
bash scripts/garage.sh close
bash scripts/garage.sh light-on
bash scripts/garage.sh light-off
bash scripts/garage.sh lock-remotes
bash scripts/garage.sh unlock-remotes

The helper script includes safety checks: it verifies obstruction status before closing and confirms current state before toggling.

Compatibility

  • Firmware: HomeKit firmware v3.x+ (tested on v3.4.4)
  • Protocols: Security+ 2.0 (yellow learn button), Security+ 1.0 (purple learn button)
  • Platforms: Works alongside HomeKit/Apple Home. Not compatible with Home Assistant simultaneously (HomeKit single-pair limitation). Use web API for agent control, Apple Home for Siri/manual control.
  • Vehicle sensor: Requires the optional laser parking sensor. Distance reading varies by vehicle position.

Notes

  • HomeKit pairing is separate from the web API. Both can operate simultaneously.
  • The device broadcasts mDNS as Garage-Door-XXXXXX.local where XXXXXX is derived from the MAC address.
