The `rpi_gpio` binary sensor platform allows you to read sensor values of the GPIOs of your [Raspberry Pi](https://www.raspberrypi.org/).
|
|
|
|
## {% linkable_title Configuration %}
|
|
|
|
To use your Raspberry Pi's GPIO in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# 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).
