@Colin rpi gpio 2.07 library not work with dietpi trixie? In general, they don't work on Bookworm either. The old 2.06 library works on Bulleye.

:smile: Okay so far so good. One notification pipe file from the lgpio Python library itself, created in the working dir at import time. It is documented here, used to be informed about GPIO changes, AFAIU: lg library DietPi users will get this fix with the upcoming release tomorrow or Sunday, or …

Is that a question or a statement ? I don’ t know as I haven’t tried it. We rely on user feedback to report back. If you are saying it doesn’t work, then what errors is it reporting ?

After Bullseye they replaced the rpi-gpio library with something like rpi-lgpio which was more modern etc. And since then node-red-node-pi-gpio stopped working (under the pins when I configure them as inputs and outputs it says n/a). I keep installing Bullseye but this can't go on forever.

Who replaced it ? Official Pi did I think. Did Diet-Pi not also do it ? A few more clues would be useful.

As far as I remember, the official Pi was replaced because the new library controlled the pins in a more modern way or something. Things don't work with Bookworm and Trixie. https://dietpi.com/forum/t/node-red-node-pi-gpio-library/24578

They work fine with Pi-OS. So we need to fine out what is different

Yes. The pi nodes can use lgpio so it could/should work

Im quite social currently, so thought id chip in (and sound clever) python3-rpi-lgpio RPi.GPIO (used by the python helper for the Node RED Node) depends on an old library - no longer around in recent RPI OS's, and the shim above is a proxy to the new lib (lgpio), and polyfils the missing lib tha…

Yes correct AFAIK. And the default script checks for it. But I’ve no idea if the Diet-Pi installs it. ( and generally it’s a bad idea to mix the default script with the Diet-Pi installer - you can but it’s a one way deal so in general don’t).

I am just a user and I can install Dietpi and Node red and that's where my competence ends. I have made several attempts with a fresh installation and what is shown here https://dietpi.com/forum/t/node-red-node-pi-gpio-library/24578 but things work half-heartedly or not at all. I tried that too ht…
