RGBWW Light =========== .. seo:: :description: Instructions for setting up RGBWW lights. :image: rgbw.png The ``rgbww`` light platform creates an RGBWW (cold white + warm white) light from 5 :ref:`float output components ` (one for each channel). The cold and warm white channels can be controlled individually or together, see :ref:`cwww_mixing` for more information. .. code-block:: yaml # 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 :ref:`max_power ` on individual output channels: .. code-block:: yaml # 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% .. note:: Remember that ``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%*. 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 :ref:`light control actions `. Configuration variables: ------------------------ - **name** (**Required**, string): The name of the light. - **red** (**Required**, :ref:`config-id`): The id of the float :ref:`output` to use for the red channel. - **green** (**Required**, :ref:`config-id`): The id of the float :ref:`output` to use for the green channel. - **blue** (**Required**, :ref:`config-id`): The id of the float :ref:`output` to use for the blue channel. - **cold_white** (**Required**, :ref:`config-id`): The id of the float :ref:`output` to use for the cold white channel. - **warm_white** (**Required**, :ref:`config-id`): The id of the float :ref:`output` 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 :ref:`rgbw_color_interlock` for more information. Defaults to ``false``. - **effects** (*Optional*, list): A list of :ref:`light effects ` to use for this light. - **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation. - All other options from :ref:`Light `.
