:description: Instructions for setting up RGBWW lights.

|
||
|
||
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 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 <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: ...
|
||
id: output_component1
|
||
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 <light-turn_on_action>`.
|
||
|
||
|
||
Configuration variables:
|
||
------------------------
|
||
|
||
- **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 <https://en.wikipedia.org/wiki/Mired>`__ 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 <https://en.wikipedia.org/wiki/Mired>`__ 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``.
|
||
- All other options from :ref:`Light <config-light>`.
