Node-RED + GPIO not working after upgrade to 9.10

Troubleshooting
1

Hello,
Running dietpi on RPI3b+ for years now, couple of months ago upgraded to bookworm, no issues.
after recent (5days ago) dietpi-update to 9.10 it seems it broken somehow GPIO communication to the Node-RED.

Initially it shown “stopped” with red under the gpio block in node-red, after some tryouts it now saying OK under the GPIO block, but it’s yellow - so it’s not comunnicating properly.

sadly (my bad) I can’t roll update back as I have backup after update :slight_smile:

Not really sure what to look for, as it was working just fine for years now.

what I’ve tried is to:

install pigpiod (no luck)
reinstall rpi.gpio
reinstall node-red
upgrade node-red
run node-red as root

There are no errors in the node-red log.

Has something changed in 9.10 dietpi?
Someone who points me to the right direction will be really appreciated :slight_smile:

update:
on other rpi which runs DHT sensor i2c, and PIR sensor on some pin, I can see same issue with communication with gpio:

sudo python3 scripts/climate.py 
/usr/local/lib/python3.11/dist-packages/gpiozero/devices.py:300: PinFactoryFallback: Falling back from lgpio: No module named 'lgpio'
  warnings.warn(

    GPIO.add_event_detect(

So i guess it must be related to the 9.10 release of the Dietpi @MichaIng ?

update:

been able to solve second issue by removing rpi-gpio and installing rpi-lgpio

sudo apt remove python3-rpi.gpio

sudo apt install python3-rpi-lgpio

Node-RED update:
I was not able to fix it for rpi-gpio node (yet), but managed to install pi-gpiod node and install pigpio again, as it seems it’s not part of the dietpi.
This works.

anyway I’d like to find out why original node stopped working after upgrade :person_shrugging:
