GPIOZERO-ENV(7)

NAME
gpiozero-env - GPIO Zero environment vars

All utilities provided by GPIO Zero accept the following environment variables:

    GPIOZERO_PIN_FACTORY
        The library to use when communicating with the GPIO pins. Defaults to attempting to load lgpio, then RPi.GPIO, then pigpio, and finally uses a native Python implementation. Valid values include "lgpio", "rpigpio", "pigpio", "native", and "mock". The latter is most useful on non-Pi platforms as it emulates a Raspberry Pi model 3B (by default).

    PIGPIO_ADDR
        The hostname of the Raspberry Pi the pigpio library should attempt to connect to (if the pigpio pin factory is being used). Defaults to localhost.

    PIGPIO_PORT
        The port number the pigpio library should attempt to connect to (if the pigpio pin factory is being used). Defaults to 8888.
