PWM LED - Home Assistant
The rpi_gpio_pwm platform allows to control multiple lights using pulse-width modulation, for example led strips. It supports one-color, RGB and RGBW leds driven by GPIOs of an Raspberry Pi or a PCA9685 controller.

+To enable this platform, add the following lines to your configuration.yaml:
# Example configuration.yaml entry
light :
- platform : rpi_gpio_pwm
- leds :
- # One-color led directly connected to GPIO
- - name : Lightstrip Cupboard
- driver : gpio
- pins : [ 17 ]
- type : simple
- # RGB led connected to PCA9685 controller
- - name : TV Backlight
- driver : pca9685
- pins : [ 0 , 1 , 2 ] # [R, G, B]
- type : rgb
- # RGBW led connected to PCA9685 controller
- - name : Lightstrip Desk
- driver : pca9685
- pins : [ 3 , 4 , 5 , 6 ] # [R, G, B, W]
- type : rgbw
+ - platform : rpi_gpio_pwm
+ leds :
+ - name : Lightstrip Cupboard
+ driver : gpio
+ pins : [ 17 ]
+ type : simple
Configuration variables:
- leds array (Required ):
+ leds array (Required ): Can contain multiple LEDs.
- name (Required ): The name of the led.driver (Required ): The driver, which controls the led. Choose either gpio or pca9685.pins (Required ): The pins connected to the led. The order of pins is determined by the specified type.type (Required ): The type of led. Choose either rgb, rgbw or simple.name (Required ): The name of the LED.driver (Required ): The driver which controls the LED. Choose either gpio or pca9685.pins (Required ): The pins connected to the LED as a list.. The order of pins is determined by the specified type.type (Required ): The type of LED. Choose either rgb, rgbw or simple.freq (Optional ): The PWM frequency. (Default: 200)address (Optional ): The address of the PCA9685 driver. (Default: 0x40)
+In this section you find some real life examples of how to use this sensor.
+This example uses a PCA9685 controller to control a RGB LED.
