I found the current documentation confusing as it did not clearly state whether the code is look at the pin # or GPIO #. Looking on the forums others were having the same issue. My goal is to make it clear that GPIO # is what users should be entering into their configs.

The `rpi_gpio` switch platform allows you to control the GPIOs of your [Raspberry Pi](https://www.raspberrypi.org/).
|
|
|
|
To use your Raspberry Pi's GPIO in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
switch:
|
|
- platform: rpi_gpio
|
|
ports:
|
|
11: Fan Office
|
|
12: Light Desk
|
|
```
|
|
|
|
Configuration variables:
|
|
|
|
- **ports** array (*Required*): Array of used ports.
|
|
- **port: name** (*Required*): Port numbers and corresponding names (GPIO #).
|
|
- **invert_logic** (*Optional*): If true, inverts the output logic to ACTIVE LOW. Default is false (ACTIVE HIGH).
|
|
|
|
For more details about the GPIO layout, visit the Wikipedia [article](https://en.wikipedia.org/wiki/Raspberry_Pi#GPIO_connector) about the Raspberry Pi.

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