homeassistant.components.switch.rpi_gpio
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Allows to control the GPIO pins of a Raspberry Pi.
Note: To use RPi GPIO, Home Assistant must be run as root.
Configuration:
switch:
platform: rpi_gpio
active_state: "HIGH"
ports:
11: Fan Office
12: Light Desk
Variables:
active_state
*Optional
Defines which GPIO state corresponds to a ACTIVE switch. Default is HIGH.
ports
*Required
An array specifying the GPIO ports to use and the name to use in the frontend.
