Update switch.rpi_gpio.markdown (#3662) 
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.

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 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 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.

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