Home Assistant Raspberry Pi GPIO custom integration

This is a spin-off from the original Home Assistant integration, which was removed in Home Assistant Core version 2022.6.

The rpi_gpio integration supports the following platforms: Binary Sensor, Cover, Switch

Installation

HACS

The recommend way to install rpi_gpio is through HACS.

Manual installation

Copy the rpi_gpio 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 folder and all of its contents into it.

Usage

Binary Sensor

The rpi_gpio binary sensor platform allows you to read sensor values of the GPIOs of your Raspberry Pi.

Configuration

Legacy binary sensor configuration

To use your Raspberry Pi's GPIO in your installation, add the following to your configuration.yaml file:

# Basic configuration.yaml entry
binary_sensor:
  - platform: rpi_gpio
    sensors:
      - port: 11
        name: "PIR Office"
      - port: 12
        name: "PIR Bedroom"

# Full configuration.yaml entry
binary_sensor:
  - platform: rpi_gpio
    sensors:
      - port: 11
        name: "PIR Office"
        unique_id: "pir_office_sensor_port_11"
        bouncetime: 80
        invert_logic: true
        pull_mode: "DOWN"
      - port: 12
        name: "PIR Bedroom"
        unique_id: "pir_bedroom_sensor_port_12"

Options

Key	Required	Default	Type	Description
sensors	yes		list	List of sensor IO ports (BCM mode pin numbers)
name	yes		string	The name for the binary sensor entity
unique_id	no		string	An ID that uniquely identifies the sensor. Set this to a unique value to allow customization through the UI
bouncetime	no	50	integer	The time in milliseconds for port debouncing
invert_logic	no	false (ACTIVE HIGH)	boolean	If true, inverts the output logic to ACTIVE LOW
pull_mode	no	UP	string	Type of internal pull resistor to use: UP - pull-up resistor, DOWN - pull-down resistor

Cover

The rpi_gpio cover platform allows you to use a Raspberry Pi to control your cover such as Garage doors.

It uses two pins on the Raspberry Pi.

• The state_pin will detect if the cover is closed, and
• the relay_pin will trigger the cover to open or close.

Although you do not need Andrews Hilliday's software controller when you run Home Assistant, he has written clear instructions on how to hook your garage door and sensors up to your Raspberry Pi, which can be found here.

Configuration

To enable Raspberry Pi Covers in your installation, add the following to your configuration.yaml file:

# Basic configuration.yaml entry
cover:
  - platform: rpi_gpio
    covers:
      - relay_pin: 10
        state_pin: 11

# Full configuration.yaml entry
cover:
  - platform: rpi_gpio
    relay_time: 0.2
    invert_relay: false
    state_pull_mode: "UP"
    invert_state: true
    covers:
      - relay_pin: 10
        state_pin: 11
      - relay_pin: 12
        state_pin: 13
        name: "Right door"
        unique_id: "right_door_cover_port_13"

Options

Key	Required	Default	Type	Description
relay_time	no	0.2	float	The time that the relay will be on for in seconds
invert_relay	no	false	boolean	Invert the relay pin output so that it is active-high (True)
state_pull_mode	no	UP	string	The direction the State pin is pulling. It can be UP or DOWN
invert_state	no	false	boolean	Invert the value of the State pin so that 0 means closed
covers	yes		list	List of covers
relay_pin	yes		integer	The pin of your Raspberry Pi where the relay is connected
state_pin	yes		integer	The pin of your Raspberry Pi to retrieve the state
name	no		string	The name for the cover entity
unique_id	no		string	An ID that uniquely identifies the cover. Set this to a unique value to allow customization through the UI

Remote Raspberry Pi Cover

If you don't have Home Assistant running on your Raspberry Pi and you want to use it as a remote cover instead, there is a project called GarageQTPi that will work remotely with the MQTT Cover Component. Follow the GitHub instructions to install and configure GarageQTPi and once configured follow the Home Assistant instructions to configure the MQTT Cover.

Switch

The rpi_gpio switch platform allows you to control the GPIOs of your Raspberry Pi.

Configuration

Legacy switch configuration

To use your Raspberry Pi's GPIO in your installation, add the following to your configuration.yaml file:

# Basic configuration.yaml entry
switch:
  - platform: rpi_gpio
    switches:
      - port: 11
        name: "Fan Office"
      - port: 12
        name: "Light Desk"

# Full configuration.yaml entry
switch:
  - platform: rpi_gpio
    switches:
      - port: 11
        name: "Fan Office"
        unique_id: "fan_office_switch_port_11"
      - port: 12
        name: "Light Desk"
        unique_id: "light_desk_switch_port_12"
        invert_logic: true

Options

Key	Required	Default	Type	Description
switches	yes		list	List of switch IO ports (BCM mode pin numbers)
name	yes		string	The name for the switch entity
unique_id	no		string	An ID that uniquely identifies the switch. Set this to a unique value to allow customization through the UI
invert_logic	no	false	boolean	If true, inverts the output logic to ACTIVE LOW

A common question is what does Port refer to, this number is the actual GPIO #, not the pin #. For example, if you have a relay connected to pin 11 its GPIO # is 17.

# Basic configuration.yaml entry
switch:
  - platform: rpi_gpio
    switches:
      - port: 17
        name: "Speaker Relay"
