I changed the udev loglevel to info and see: <snip> please only include relevant logs. We don't support the gpio sysfs means of accessing GPIO, it's been deprecated since around the 4.8 kernel. > Any tips? Or am I stuck running Nvidia's linux for it to work? The replacement mechanism is the GPIO character interface where the GPIO is available via /dev/gpiochip* or through the libgpiod userspace utils and python3 bindings in the python3-libgpiod package. I've not looked but I would guess there's support for this interface on NodeRED as it's been around for some time.
