node-red-contrib-node-hue 0.9.0

Control Philips HUE lights using Node-RED.

npm install node-red-contrib-node-hue

An solution to control Philips Hue lights using Node-Red, uses node-hue-api library for communicating with the lights.

This module provides input and output nodes for communicating with Philips Hue lights, the input node accepts multiple color format and automatically converts the values to the right format.


  • Control both groups and individual lights.
  • Convert input arguments to light specific arguments
  • Trigger events for light changes
  • Self syncing, uses background polling to detect external changes to light
  • Displays current state for light in the Node-Red ui


  • The HSV to XY (and back) color conversion is not 100% correct, modifying only one color channel at a time does not produce correct result.


Dashboard example config:

This is an example of how to control the light using the node-red-dashboard The split node is used to get the on and bri payload from the light status message, and the join is used to combine the topic and value to an JSON object.

UI example

Wakeup example config:

Simple example of using an inject node to trigger an wakeup light behavior every workday, the light transitions from off to on with 75% brightness over an duration of 30s.

Input node

The light is controlled by sending message with an payload containing the new state

Simplified control by sending the following values as payload

Value Info
'on' or true Turn light on
'off'or false Turn light off
numeric value Turn light on and set brightness (0-100%)

More advanced way to control the light is to send an object payload with one or more of the following properties set

Property Info
on Set light state (true/false)
red, green and/or blue Set one or more color channel for light (0-255)
hex Set color (#f49242)
hue Set color hue (0-360)
xy Set XY color (array with 0.0-1.0 values)
x and/or y Set XY color (0.0-1.0)
sat or saturation Set color saturation (0-100)
bri or brightness Set light brightness (0-100%)
cr, mired or mirek Set Mired color temperature (153 - 500)
kelvin Set kelvin color temperature (2200-6500)
duration Transition time (ms)

Example: Sending the following to the light will turn it on and dim it upp to 77% over 10 seconds

  "payload": {
    "on": true, 
    "bri": 77,
    "duration": 10000

Using withouth Node-RED

This library can be used independent from Node-RED, the example/mqtt.js file contains an simple example using MQTT.js to enable control an lights on/off status and brightness over MQTT.

The MQTT topic lights will contain an list of all currently detected lights. Specific light can be controlled by sending an message to the topics lights/<id>/on (boolean) or lights/<id>/brightness (number) with the new state.
