The ``rgbw`` light platform creates an RGBW light from 4 :ref:`float output components <output>` (one for each channel).
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
light:
|
|
- platform: rgbw
|
|
name: "Livingroom Lights"
|
|
red: output_component1
|
|
green: output_component2
|
|
blue: output_component3
|
|
white: output_component4
|
|
|
|
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.
|
|
- **white** (**Required**, :ref:`config-id`): The id of the float :ref:`output` to use for the white channel.
|
|
- **effects** (*Optional*, list): A list of :ref:`light effects <light-effects>` to use for this light.
|
|
- **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``.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- All other options from :ref:`Light <config-light>`.

Color Interlock
|
|
***************
|
|
|
|
With some LED bulbs, setting the RGB channels to maximum whilst wanting a white light will have a undesired
|
|
hue affect. Additionally, the brightness command may not work as expected depending upon configuration,
|
|
leaving users to adjust the white component level separately. For these cases a new configration variable
|
|
has been added: color_interlock.
|
|
|
|
Setting this variable to True will turn off RGB leds when white value is above 0 (or if they are to 255,255,255)
|
|
and turn off white leds if color is not set to 255,255,255. This also allows the brightness parameter to
|
|
control the intensity of the white leds.
