Argon 1 Case and Argon Fan HAT controller for Ubuntu

Argon Fan Controller

Argon Fan HAT / Argon ONE Case Fan Controller for Ubuntu

Made with 💝 for

Introduction

argon1.sh is a refactored version of the Argon FanHAT / Argon ONE Case Fan controller for Ubuntu and is derived from the origin script published by Argon Forty here:

• https://download.argon40.com/argon1.sh

The refactor consisted of:

• Adds support for Ubuntu by reading temps from sysfs.
• Adds support for Ubuntu 20.04 by only using Python 3.
• Uses here documents to make the script easier to read/maintain.
• Simplifies install/uninstall via an option parser.
• Removes the config script and desktop icons.

We have a Discord for this project:

argon1-ubuntu's Issues

Test for no argument? - fixed?

Hi,
I installed the beta Mate desktop on my Pi3B+ yesterday and also this script as the Pi's in an Argon 1 case. If I run the script without supplying an argument it displays the msg on line 18 and then exits, its been many years since I tangled with case statements but it looks like noarg is not detected, maybe it could just call usage?
Cheers
Tony

Shutdown via OS menu not working with script?

I have the argon for ubuntu script installed on my pi4 8gb model running Ubuntu MATE 20.04. The fans and power buttons function as expected and the same as they do when using my Raspberry OS 64 image except when doing a shutdown. When selecting shutdown from the menu in Ubuntu the system will power off, but the red status light will not turn off. The board does not seem to register the system in an off state. The system will not respond to the power button at this point and will not turn on. Unplugging the power is the only way to reset the system and allow the power button to function and turn the system back on.

Under Raspberry OS 64 selecting the shutdown option within the OS will shut down the Pi4 and the red light will turn off. Pressing the power button on the case will then turn the system back on as expected.

for 4B, also need **bus = smbus.SMBus(1)**

somewhere like this need to be modified

if rev == 2 or rev == 3:
bus = smbus.SMBus(1)
else:
bus = smbus.SMBus(0)

Power button no longer works on 22.10

Soft shutdown and reboot no longer work on 22.10. Not entirely sure what's changed, considering the button presses worked fine on 22.04
