Home Assistant Raspberry Pi GPIO PWM custom integration

This is a spin-off from the original Home Assistant integration which was marked as deprecated and will be removed in Home Assistant Core 2022.4.

The rpi_gpio_pwm platform allows to control multiple lights or fans using pulse-width modulation, for example LED strips. It supports one-color LEDs or fans driven by GPIOs of a Raspberry Pi (same host or remote) For controlling the GPIOs, the platform connects to the pigpio-daemon (http://abyz.me.uk/rpi/pigpio/pigpiod.html), which must be running. On Raspbian Jessie 2016-05-10 or newer the pigpio library is already included. On other operating systems it needs to be installed first (see installation instructions: https://github.com/soldag/python-pwmled#installation).

For Home Assistant this daemon can be installed as an add-on (https://github.com/Poeschl/Hassio-Addons/tree/master/pigpio).

Installation

HACS

The recommend way to install rpi_gpio_pwm is through HACS.

Manual installation

Copy the rpi_gpio_pwm folder and all of its contents into your Home Assistant's custom_components folder. This folder is usually inside your /config folder. If you are running Hass.io, use SAMBA to copy the folder over. You may need to create the custom_components folder and then copy the rpi_gpio_pwm folder and all of its contents into it.

Configuration

To enable this platform, add the following lines to your configuration.yaml:

# Example configuration.yaml entry for lights
light:
  - platform: rpi_gpio_pwm
    leds:
      - name: Lightstrip Cupboard
        pin: 17
        unique_id: thisismyuniqueid

# Example configuration.yaml entry for fans
fan:
  - platform: rpi_gpio_pwm
    fans:
      - name: RPI Cooling Fan
        pin: 12
        unique_id: thisismyuniqueid

CONFIGURATION VARIABLES

• leds list (REQUIRED if lights): Can contain multiple LEDs.

• fans list (REQUIRED if fans): Can contain multiple FANs.

• name string (REQUIRED): The name of the LED for light config or the name of the FAN for fan config.

• pin integer (REQUIRED): The pin connected to the LED as a list for light config or the pin connected to the FAN for fan config..

• unique_id string (REQUIRED): An ID that uniquely identifies this LED or FAN. Set this to a unique value to allow customization through the UI.

• frequency integer (optional, default: 100): The PWM frequency for light config.

• host string (optional, default: localhost): The remote host address for the GPIO driver.

• port integer (optional, default: 8888): The port on which the GPIO driver is listening.
