Problems building opengpio when installing the MMM-GPIO-Notifications module

wishmaster270

I will try to take a closer look at the problem in the next days.
I do not have a setup with Debian 13 at the moment and it will take me some time.
Did not test 2.x of open gpio yet. Maybe the api changed.

Make sure you set up the pull-up/pull-down resistor like described in this description

@wishmaster270 Great - thanks

Here is some more info in case it helps:

As well as a pull-down resistor, I also tried a pull up, and tried without any resistor - neither sent notifications.

To double check, I used Python (RPi.GPIO) and received the events from GPIO 17 when the switch was closed.

Rasberry Pi OS was install around Nov 2 2025 using the Rasberry Pi imager

$ uname -a
Linux raspberrypi 6.12.47+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.12.47-1+rpt1 (2025-09-16) aarch64 GNU/Linux

Hi and sorry for the late reply.

I released a new version of the module a couple of minutes ago which should fix the problem.

It uses the new version of the lib for newer operation systems and changes to a other branch if it is a old debian otherwise.

As expected the api of the lib changed and i needed to do a small change in the modules node_helper.js.

Now works great on my RasberryPi - thanks

Great to hear that. As I am using Debian 12 at the moment I am optimistic it is working for older installations, too.

I think the topic is solved then.
