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
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%
gamma_correct is enabled by default (
γ=2.8), and you may want take it into account for the calibration. For instance if you command a light to 50% brightness and want it to be the new maximum:
max_PWM_power = max_light_power^2.8 = 0.5^2.8 = 0.144, then you would set
max_power to 14.4%.
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
Setting this option to
true will result in the light having two color modes available,
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
color_mode option of the light control actions.
name (Required, string): The name of the light.
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
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
effects (Optional, list): A list of light effects to use for this light.
id (Optional, ID): Manually specify the ID used for code generation.
