RGBWW Light
===========

: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 <output>` (one for each channel). The cold white
and warm white channels will be mixed using the color temperature configuration options.
.. 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 <config-output>` 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%
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** (**Required**, float): The color temperate (in `mireds <https://en.wikipedia.org/wiki/Mired>`__ or Kelvin)
of the cold white channel.
- **warm_white_color_temperature** (**Required**, float): The color temperate (in `mireds <https://en.wikipedia.org/wiki/Mired>`__ or Kelvin)
of the warm white channel.
- **effects** (*Optional*, list): A list of :ref:`light effects <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 <config-light>`.
