RGBWW Light

The rgbww light platform creates an RGBWW (cold white + warm white) light from 5 float output components (one for each channel). The cold and warm white channels can be controlled individually or together, see Mixing for more information.

# Example configuration entry
light:
  - platform: rgbww
    name: "Livingroom Lights"
    red: output_component1
    green: output_component2
    blue: output_component3
    cold_white: output_component4
    warm_white: output_component5
    cold_white_color_temperature: 6536 K
    warm_white_color_temperature: 2000 K

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%

Color Interlock

With some LED bulbs, it is not possible to enable the RGB leds at the same time as the white leds, or setting the RGB channels to maximum whilst wanting a white light will have an undesired hue effect. For these cases a configuration variable is available that prevents the RGB leds and white leds from being turned on at the same time: color_interlock.

Setting this option to true will result in the light having two color modes available, RGB and COLD_WARM_WHITE. When the RGB color mode is active, the white leds are turned off, and when the COLD_WARM_WHITE color mode is active, the RGB leds are turned off. Switching between these modes can be done from the Home Assistant interface, or by using the color_mode option of the light control actions.

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.

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

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

  • cold_white_color_temperature (Optional, float): The color temperature (in mireds or Kelvin) of the cold white channel. Note that when the color interlock is enabled, this option is required to control the light from Home Assistant.

  • warm_white_color_temperature (Optional, float): The color temperature (in mireds or Kelvin) of the warm white channel. Note that when the color interlock is enabled, this option is required to control the light from Home Assistant.

  • constant_brightness (Optional, boolean): When enabled, this will keep the overall brightness of the cold and warm white channels constant by limiting the combined output to 100% of a single channel. This reduces the possible overall brightness but is necessary for some power supplies that are not able to run both channels at full brightness at once. Defaults to false.

  • 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.

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

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

  • All other options from Light.
