API Overview

Homebridge Config UI X exposes a REST API. View full documentation at {HOMEBRIDGE_URL}/swagger.

Authentication

All API calls require a Bearer token. Obtain it first:

# Get auth token
TOKEN=$(curl -s -X POST "${HOMEBRIDGE_URL}/api/auth/login" \
  -H "Content-Type: application/json" \
  -d "{\"username\":\"${HOMEBRIDGE_USERNAME}\",\"password\":\"${HOMEBRIDGE_PASSWORD}\"}" \
  | jq -r '.access_token')

Common Operations

List All Accessories

curl -s "${HOMEBRIDGE_URL}/api/accessories" \
  -H "Authorization: Bearer ${TOKEN}" | jq

Response includes accessory uniqueId, serviceName, type, and current values.

Get Accessory Layout (Rooms)

curl -s "${HOMEBRIDGE_URL}/api/accessories/layout" \
  -H "Authorization: Bearer ${TOKEN}" | jq

Control an Accessory

Use PUT to update accessory characteristics:

# Turn on a light/switch
curl -s -X PUT "${HOMEBRIDGE_URL}/api/accessories/{uniqueId}" \
  -H "Authorization: Bearer ${TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"characteristicType": "On", "value": true}'

# Turn off
curl -s -X PUT "${HOMEBRIDGE_URL}/api/accessories/{uniqueId}" \
  -H "Authorization: Bearer ${TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"characteristicType": "On", "value": false}'

# Set brightness (0-100)
curl -s -X PUT "${HOMEBRIDGE_URL}/api/accessories/{uniqueId}" \
  -H "Authorization: Bearer ${TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"characteristicType": "Brightness", "value": 50}'

# Set color (Hue: 0-360, Saturation: 0-100)
curl -s -X PUT "${HOMEBRIDGE_URL}/api/accessories/{uniqueId}" \
  -H "Authorization: Bearer ${TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"characteristicType": "Hue", "value": 240}'

# Set thermostat target temperature
curl -s -X PUT "${HOMEBRIDGE_URL}/api/accessories/{uniqueId}" \
  -H "Authorization: Bearer ${TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"characteristicType": "TargetTemperature", "value": 22}'

Control Devices

# Turn on/off

scripts/homebridge_api.py set <uniqueId> On false

# Adjust brightness
scripts/homebridge_api.py set <uniqueId> Brightness 75

# Set color

Tips

• Find your accessory's uniqueId by listing all accessories first
• The API documentation at /swagger shows all available endpoints
• Characteristic names are case-sensitive (use On not on)
• Some accessories may have multiple services; check the response for service types
• Token expires after some time; re-authenticate if you get 401 errors
