hue-to-mqtt

mqtt-smarthome

Convert Philips Hue messages to mqtt messages.

Why another hue-mqtt-bridge?

  • Support for Friends of Hue switches.
  • I like to switch to zigbee2mqtt for my hue lights at some point of time. The light messages are compatible with this format.
  • Completely written using Hue API v2
  • Server-Sent Events

Docker

This application is intended to be executed using docker. Example docker compose usage:

huemqtt:
  hostname: huemqtt
  image: pharndt/hue2mqtt:2.5.1
  volumes:
    - ./config/huemqtt:/var/lib/huemqtt:ro
  restart: always 
  depends_on:
   - mosquitto

Supported devices

  • Lights
  • Philips Switches
  • Friends of Hue Switches
  • Temperature sensors
  • Presence sensors
  • Daylight sensors
  • Ambient light sensors

Example message

The message will be posted to the following topic: hue/light/room/some-light

{
    "state":"ON",
    "brightness":254,
    "color_temp":230
}

Note that unreachable lights are handled as they are turned off.

Post a message

{
    "state":"OFF"
}

to the topic hue/light/room/some-light/set to turn the light off.

Post a message

{
    "state":"ON",
    "brightness":254,
    "color_temp":230
}

to the topic hue/light/room/some-light/set to turn the light on with the given brightness and color_temp.

Color

{
    "state":"ON",
    "brightness":254,
    "color":{"x":0.3691,"y":0.3719}
}

Get sate

Post a message {"state": ""} to hue/light/room/some-light/get to get the current light state.

Switch

{
    "button":1,
    "code":1000,
    "last-updated":"2021-01-09T13:08:17Z[UTC]"
}

Example configuration

{
    "mqtt": {
        "url": "tcp://192.168.2.98:1883",
        "username": "user",
        "password": "password"
    },
    "hue": {
        "host": "192.168.2.99",
        "api-key": "api-key-here"
    },
    "names": {
        "resource-uuid": "office"
    },
    "loglevel": "debug"
}

Name mappings

for resources without an own name (like light groups) or when you like to define a custom name, you can use the names configuration.

Without a name configuration, the name will be generated from

  • the room (when available)
  • the name defined by Hue (when available)
  • the resource UUID as fallback

Bridge status

The bridge maintains two status topics:

Topic: .../bridge/state

Value Description
online The bridge is started
offline The bridge is currently not started.

Raspberry PI OS note

When you get the following message on Raspberry PI OS:

#
# Fatal error in , line 0
# unreachable code
