Run python gpio script as another user than root

Radim Vesely

Hi,
i'm trying to run python gpio script (with pyOnionGpio library) as another user than root.
There is problem with privileges on directory /sys/class/gpio.

I've tried change owner of that folder with chown -R alice:alice /sys/class/gpio/ and run script sudo -u alice ./script.py

Script throw exception IOError: [Errno 13] Permission denied: '/sys/class/gpio/gpio18/direction'. New created link /sys/class/gpio/gpio18/ is created by root.

Do you now some way how to run python gpio script as another user than root?

Thank you, Radim

@Radim-Vesely
hum the official firmware has only one user (root) and there is no sudo command. are you running a custom build of the OS?

i'm running official firmware and I install sudo opkg install sudo and create user alice.
