RGB Light¶
The rgb
light platform creates an RGB light from 3 float output components
(one for each color channel).
# Example configuration entry
light:
- platform: rgb
name: "Living Room Lights"
red: output_component1
green: output_component2
blue: output_component3
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 max_power on individual output channels:
# 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, ID): The id of the float Output Component to use for the red channel.
green (Required, ID): The id of the float Output Component to use for the green channel.
blue (Required, ID): The id of the float Output Component to use for the blue channel.
