The ``rgb`` light platform creates an RGB light from 3 :ref:`float output components <output>`
|
||
(one for each color channel).

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: rgb
|
||
name: "Living Room Lights"
|
||
red: output_component1
|
||
green: output_component2
|
||
blue: output_component3
|
||
|
||
# Example output entry
|
||
output:
|
||
- platform: ...
|
||
id: output_component1
|
||
max_power: 80%
|
||
# Repeat for green and blue output
|
||
|
||
.. 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%*.
|
||
|
||
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.
|
||
- All other options from :ref:`Light <config-light>`.
