Fan control stopped working

After trying lots of things, multiple uninstall/reinstall attempts, I managed to install your updated script.
Now the services (argononed, argoneond) sometimes start, sometimes they don’t.

My OS details are:

pi@vault:~ $ cat /etc/os-release
Linux vault 5.15.84-v8+ #1613 SMP PREEMPT Thu Jan 5 12:03:08 GMT 2023 aarch64 GNU/Linux

pi@vault:~ $ cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

I’m also running the latest version of OpenMediaVault 6.

I cannot pinpoint the specific reason why the services either work or they don’t. When they don’t, whenever I run sudo systemctl start argononed.service it gets stuck without any output and status shows Active: inactive (dead). When they do, they do.

In both cases I have attached a display to the pi and watched the boot process carry on without issues.

One thing I have yet to try is use a different sd card (in the eventuality it encounters some weird read error), but I don’t have one right now. I will do that once I get a hold of one, although I doubt that is the case.
