The rpi_gpio integration is the base for all related GPIO platforms in Home Assistant. There is no setup needed for the integration itself, for the platforms please check their corresponding pages.

Binary Sensor

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

Configuration

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

# Example configuration.yaml entry
binary_sensor:
  - platform: rpi_gpio
    ports:
      11: PIR Office
      12: PIR Bedroom

{% configuration %} ports: description: List of used ports. required: true type: map keys: "port: name": description: The port numbers (BCM mode pin numbers) and corresponding names. required: true type: string bouncetime: description: The time in milliseconds for port debouncing. required: false type: integer default: 50 invert_logic: description: If true, inverts the output logic to ACTIVE LOW. required: false type: boolean default: "false (ACTIVE HIGH)" pull_mode: description: > Type of internal pull resistor to use. Options are UP - pull-up resistor and DOWN - pull-down resistor. required: false type: string default: "UP" {% endconfiguration %}

For more details about the GPIO layout, visit the Wikipedia article about the Raspberry Pi.

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:

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

{% configuration %} relay_time: description: The time that the relay will be on for in seconds. required: false default: 0.2 type: float invert_relay: description: Invert the relay pin output so that it is active-high (True). required: false default: false type: boolean state_pull_mode: description: The direction the State pin is pulling. It can be UP or DOWN. required: false default: UP type: string invert_state: description: Invert the value of the State pin so that 0 means closed. required: false default: false type: boolean covers: description: List of your doors. required: true type: list keys: relay_pin: description: The pin of your Raspberry Pi where the relay is connected. required: true type: integer state_pin: description: The pin of your Raspberry Pi to retrieve the state. required: true type: integer name: description: The name to use in the frontend. required: false type: string {% endconfiguration %}

Full example

# Example 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'

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

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

# Example configuration.yaml entry
switch:
  - platform: rpi_gpio
    ports:
      11: Fan Office
      12: Light Desk

{% configuration %} ports: description: Array of used ports. required: true type: list keys: port: description: Port numbers and corresponding names (GPIO #). required: true type: [integer, string] invert_logic: description: If true, inverts the output logic to ACTIVE LOW. required: false default: false type: boolean {% endconfiguration %}

For more details about the GPIO layout, visit the Wikipedia article about the Raspberry Pi.

Note that a pin managed by HASS is expected to be exclusive to HASS.

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.

# Example configuration.yaml entry
switch:
  - platform: rpi_gpio
    ports:
      17: Speaker Relay
