Thanks for your help, , but it did not solve the error.
I still get:[2025-02-28 22:27:10.007] [ERROR] Whoops! There was an uncaught exception...

@crowimu and you rebooted?
-
@sdetweil Yes, sure. I assume there must have been a change in the GPIO handling, but have not figured out where. :(

@crowimu
Only thing that comes in my mind that you have either put cable on wrong GPIO or cable is broken.As per default you have either to use GPIOPins: [26,20,19]//rotary cw, rotary ccw, rotary press (BCM Numbering - marked yellow in the above picture) or (if occupied) enter the correct BCM (!) numbers in config of module.
If this is all correct, module should work.

@crowimu Last thought - after some googeling…
Axled (the author has a thread about his module.
In one of his posting he stated
“rotation and click (Button press) uses the same library (onOff).”.“node_modules/onoff/onoff” is part of your error-listing.
So I can imagine you need this onoff -library to read the GPIO-output.
Further research on this let me assume that onoff in some kind is associated to node.js (@sdetweil for sure knows more on this than me…).At least one onoff library in this context is this one - but I’m not sure if this is the right one.
May you give it a try…edit: I’ve just checked - on my own mirror there is NO onoff directory in “MagicMirror/node_modules/”
Good luck.

@crowimu Found in completely different context another hint to onoff - also related to GPIO (in concrete a GPIO related implemetation of a rotary decoder).
There was a suggestionnpm install --save onoff@6.0.0
I currently only „assume“ that @6.0.0 is the version - cause the cited post is from 2021 there could be a new version.
A quick google delivers this page and this one statednpm install onoff
Will do the trick…
Good luck.

@rkorell Thank you and all others for the hints, however up to now I did not manage to get the ‘onoff’ and the MMM-Navigate module workingon my system.
I have recompiled onoff, installed it globally, changed the node version.
Nothing helped yet :(I have started to create a simple module for my needs to control some fuctions with a rotary encoder,

It’s early stage, please wish me luck. :) -

@crowimu - Just a quick question: Have you considered to use a newer version of a Pi? A 4B or even 5?
Pi2 is somewhat old - may there is a kind of a root cause?Regards,

@rkorell Hi Ralf,
I think the quadcore RPi2 is quite sufficient for a Magic Mirror, but I’ve also tested it on a RPi3 with the same results.
I don’t like the power consumption of RPi4 and 5 and I also don’t like to add cooling fans to an SBC.
So up to now I have always used RPi Zero / Zero2 / RPi 1/2 and 3 smoothly for my projects. :)
