|
|
|
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: 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 :ref:`light control actions <light-turn_on_action>`.
|
|
|
|
|
|
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 <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``.
|
|
- **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>`.
