need help with setting up gpio in octoprint docker #270

Open imstupidwithlinux opened 1 year ago

imstupidwithlinux commented 1 year ago

My octoprint install is running inside a docker container and recently I've built a relay into my psu to switch it on and off but when typing kn the correct gpio pin it doesn't do anything, homebridge inside a docker container works without any problems and can switch the relay

Not sure if helps in your case, but managed to get my setup working by:

  1. Installing also https://github.com/kantlivelong/OctoPrint-PSUControl-RPiGPIO plugin
  2. Giving docker container access to GPIO pins by mounting '/dev/gpiomem' device similar to example $ docker run --device /dev/gpiomem -d whatever (from https://stackoverflow.com/a/48234752)
  3. Setting PSU control to use RPi-GPIO plugin
  4. Setting RPi-GPIO plugin to control correct pin on raspberry pi3

And I highly recommend to follow your octoprint container logs while debuging.
