This HACS integration is used to address GPIO (especially and only tested for RaspberryPi) using libgpiod and python gpiod >=v2.02 since RPI.gpio is no longer supported. I created this for my own use, and to understand a custom integration, but since it is working on Raspberry pi feel free to use.

This is working in my homeassistant environment, that's it. Shared for testing and usage at your own risk!

ha_gpiod is based on ha-rpi_gpio, which was already adapted for gpiod in ha-gpio and rewritten from scratch by me ..

Via HACS: add as custom repository from github using this github https://github.com/jdeneef/ha_gpiod/ (HACS => integrations => 3-dots menu => custom repositories, enter repository URL, select "Integrations" in Category drop-down, go back to hacs, install gpiod component, reboot, add config, reboot).
If you run into errors, ensure HACS is up-to-date, re-install HACS to update it if needed.

The gpiod platform will be initialized using the path to the gpio chip. When path is not in the config /dev/gpiochip[0-5] are tested for a gpiodevice having pinctrl, in sequence [0,4,1,2,3,5]. So with a raspberry pi you should be OK to leave the path empty.

See also configuraton-example.yaml; note that below config shows most options, and can't be used as is, since cover reuses switch and sensor ports.

# setup gpiod chip; mostly not required
gpiod:
  path: '/dev/gpiochip0'

# Example of switches (eg switched leds or buzzer) with some sample parameters
switch:
  - platform: gpiod
    switches:
      - name: "Led 1 red"
        port: 4
      - name: "Led 2 red"
        port: 17
        unique_id: "gpio_led_red_2"
      - name: "Led 3 yellow"
        port: 22
        active_low: true
      - name: "Led 6 green"
        port: 11
        bias: "AS_IS"
        drive: "PUSH_PULL"
      - name: "Buzzer"
        port: 8

# Example of binary_sensor (eg push button) setup
binary_sensor:
  - platform: gpiod
    sensors:
    - name: "Button"
      port: 7

# Example of cover setup
cover:
  - platform: gpiod
    covers:
      - relay_port: 4
        name: Cover blue
        state_port: 7
        relay_time: 1200

The gpiod binary sensor platform allows you to read sensor values of the GPIOs of your device.

The gpiod switch platform allows you to control the GPIOs of your device.

The gpiod cover platform allows you to control GPIOs to open/close covers; note that I have only verified cover functionality simulating with switches and buttons, so logic could be off on some points ..
