RGBW Light

The rgbw light platform creates an RGBW light from 4 float output components (one for each channel).

# Example configuration entry
light:
  - platform: rgbw
    name: "Livingroom Lights"
    red: output_component1
    green: output_component2
    blue: output_component3
    white: output_component4

Color Correction

It is often favourable to calibrate/correct the color produced by an LED strip light as the perceived intensity of different colors will generally vary. This can be done by using max_power on individual output channels:

# Example configuration entry
light:
  - platform: rgbw
    name: "Livingroom Lights"
    red: output_component1
    green: output_component2
    blue: output_component3
    white: output_component4

# Example output entry
output:
  - platform: esp8266_pwm
    id: output_component1
    pin: D1
    max_power: 80%

Configuration variables:

  • name (Required, string): The name of the light.

  • red (Required, ID): The id of the float Output Component to use for the red channel.

  • green (Required, ID): The id of the float Output Component to use for the green channel.

  • blue (Required, ID): The id of the float Output Component to use for the blue channel.

  • white (Required, ID): The id of the float Output Component to use for the white channel.

  • effects (Optional, list): A list of light effects to use for this light.

  • color_interlock (Optional, boolean): When enabled, this will prevent white leds being on at the same time as RGB leds. See Color Interlock for more information. Defaults to false.

  • id (Optional, ID): Manually specify the ID used for code generation.

  • All other options from Light.

Color Interlock

With some LED bulbs, setting the RGB channels to maximum whilst wanting a white light will have an undesired hue affect. Additionally, the brightness command may not work as expected depending upon configuration, leaving users to adjust the white component level separately. For these cases a new configration variable has been added: color_interlock.

Setting this variable to True will turn off RGB leds when white value is above 0 (or if they are to 255,255,255) and turn off white leds if color is not set to 255,255,255. This also allows the brightness parameter to control the intensity of the white leds.
