Power ON/OFF button - AudioPhonics - How to install a plugin?

I had a very good Volumio version 2 running on an Audiophonics box

Recently I have touched the upgrade button to Volumio version 3. Since that moment, the power on/off button is not working anymore.

It seems that there is a plugin available on this website

This is in fact a zip file for version 2.

My questions :

  • Will this also work on the Volumio Version 3 ?
  • Is this also compatible with my Hifiberry card ?
  • MOST IMPORTANT QUESTION: Can somebody explain me (for dummies procedure) on how to install this zip file after downloading the file to my PC ?

Many thanks in advance for your help.
With kind regards,


seems more people requested this. As I don;t have the hardware its dangerous to tell you what to do.
You can try to reach out to the author

Or if you want to take a walk on the wild side, I’ll take no ownership or support if it goes wrong or even fail your current installation.

sudo apt -y install build-essential
cd ~
wget https://github.com/Saiyato/volumio-audiophonicsonoff-plugin/raw/master/volumio-audiophonicsonoff-plugin.zip
mkdir ./onoff
miniunzip volumio-audiophonicsonoff-plugin.zip -d ./onoff
cd onoff
npm update  (it might be possible that this is not even needed)
npm install --save onoff@6.0.0
volumio plugin install
cd ..
rm onoff
rm volumio-audiophonicsonoff-plugin.zip

and see what happens.

I have the same device and I asked audiophonics for this plugin. For the moment, the plugin is not working, but they proposed to edit some configuration files so you can invoke directly a dtoverlay and have 90% of the functionality of the power manager without using a plugin or installing anything. Just add these two lines in /boot/userconfig.txt:

and the power manager should be functional on the next reboot. This method works on almost any system running on Raspberry Pi (but does not react to reboot / poweroff initiated from another source than the on/off button).

Just FYI: There is a PR on GitHub for a Volumio 3 version. I have no idea if it works though.

Many thanks Christianrablay,

Thanks Christian, now it’s perfect for me. The button work.

I’m very happy. Since the version 3.378, Saiyato have made the plugin in Volumio directly.
It works perfectly.
