[QUESTION] Can't get this to work

[rs-garrick]

Plugin Version
0.6.2

Question
I'm trying this plugin for the first time on octopi and a new raspberry pi 4. Install and config seems fine but it's not responding to events. A small python script using RPi.GPIO, running as the same user, responds to the button push, so at least I know the basic hardware, OS, and file privs pieces are OK.

I can see that octoprint has a file descriptor for /sys/devices/platform/soc/fe200000.gpio/gpiochip0/gpio/gpio17/value open, so it seems to be mostly good. I've enabled debug logging and I see activity when saving configs in the plugin UI.

Octoprint doesn't respond to the button. No actions will execute. Nothing is logged. strace on the octoprint process doesn't show any activity. I'm not sure how to debug from here.

Thanks in advance.

Additional context
Everything is pretty new.
Build 2024.06.18.085851 with "webcamd", based on OctoPi 1.0.0, running on Raspberry Pi 4 Model B Rev 1.5

Hi,
Could you check what version of python you are running? Additionally check the version of gpiozero. Maybe there is a version mismatch.

You can can do that by using the following commands in the terminal of the raspberry pi:

• python3 -version
• pip3 show gpiozero

Cheers,
Sam

It's just whatever came with octopi. I've not really done much to this system.

garrick@octoprint:~ $ python3 --version
Python 3.9.2
garrick@octoprint:~ $ pip3 show gpiozero
Name: gpiozero

Thank you!
This confirms my suspicion. My setup logic installed the wrong gpiozero version for your Python version. I'll try to fix this.

Hi, could you try installing the physical button plugin using the following link:
https://github.com/LuxuSam/PhysicalButton/archive/refs/heads/82-bug-on-new-installation.zip
If you're unsure how to install it via the link, first click on +Get More in the Plugin Manager tab in OctoPrint. At the bottom of that window, you can paste the link and click install.

I changed some logic and now the correct version of gpiozero should get installed!

Cheers,
Sam

So this is weird.... it worked... once? My test.sh system action was executed once. I've not gotten it to execute from the button press a second time.

Could you please attach the octoprint.log file?

To do this, enable debugging for the plugin in the settings under OctoPrint/Logging, then restart OctoPrint and try pressing a few buttons.

After that, you can download the log file in the logging settings by clicking the download button next to the file.

Just FYI, I'm out of town now. I won't be back till next week.

Hi. I'm also encountering non functionality of Physical Button plugin after install. I'm on a RPi 3a+ so I think I'm not able to use gpioero 2.1

As previous error reported, I have 1.6.2 and
I did try to install your fix from the provided url but after this i still see 1.6.2 which i think confirms the pre 5 rpis can't use this. Is Physical Button not compatible with gpiozero 1.6.2? I also show python 3.9.2
Thanks
