This is a rewritten version of the Argon One daemon.

Only the fan speed control feature was implemented.

Due to a hardware "bug" the fan speed control might not work. Please see the following thread.
I replaced the capacitor mentioned there (10uF -> 10nF).

The default config file location is /etc/default/argonone.toml.

This location can be changed by the CONFIG_FILE environment variable.

Requirements:

• smartctl (smartmontools)
• lsblk
• awk

Also requires additional python libraries:

• smbus2
• RPi.GPIO
• toml

1. Download the argonone.py file and place it in /usr/local/bin/.
2. Run chmod 755 /usr/local/bin/argonone.py.
3. Download argonone-example.toml, move it to /etc/default/argonone.toml, and adjust the configuration options.
4. Set up the systemd unit.

Please see this unit file.

You can copy it to /etc/systemd/system/ and adjust locations of the python3 binary and argonone.py if necessary.

Then execute the following as root:

systemctl daemon-reload
systemctl enable argonone.service
systemctl start argonone.service
