|
The ``cwww`` light platform creates a cold white + warm white light from 2
|
|
:ref:`float output components <output>` (one for each channel). The two channels
|
|
can be controlled individually or together.

Mixing
|
|
------
|
|
|
|
The two channels of this light can be controlled individually by using the ``cold_white`` and ``warm_white`` options of
|
|
the :ref:`light control actions <light-turn_on_action>`.
|
|
|
|
If the color temperature of both lights is supplied, it is also possible to control the two channels together by
|
|
setting a color temperature, using the ``white`` (interpreted as brightness) and ``color_temperature`` options. This
|
|
calculation assumes that both lights have the same illuminance, which might not always be accurate.
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **name** (**Required**, string): The name of the light.
|
|
- **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 this option is required to control the mixing 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 this option is required to control the mixing 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``.
|
|
- **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>`.
