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

{% linkable_title 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 variables:

• ports array (Required): Array of used ports.
  • port: name (Required): Port numbers (BCM mode pin numbers) and corresponding names.
• pull_mode (Optional): The internal pull to use (UP or DOWN). Default is UP.
• bouncetime (Optional): The time in milliseconds for port debouncing. Default is 50ms.
• invert_logic (Optional): If true, inverts the output logic to ACTIVE LOW. Default is false (ACTIVE HIGH).
