This draft PR assumes merging of another PR over at lm-sensors: lm-sensors/lm-sensors#577. The change is functional with my fork of lm-sensors: https://github.com/remiberthoz/lm-sensors/tree/reflection also it would need path adjustments for the fork on line 356 and 357.

It makes configuration of labels for temperature, fan, PWM and voltage sensors adjustable via /etc/sensors.conf, /etc/sensors3.conf or /etc/sensors.d/. It also masks sensors that are ignored by this configuration files.

--label-map parameter to 'sensors' is not implemented in the
official sensors program, but available at this fork:

Launching a subprocess is very risky. It's why I was so slow to adopt GPU stats. It is so easy to cause system stutter. I think the right course of action here is to add /etc/sensors3.conf parsing directly into Vitals. We actually talk about it in issue #83. Hoping that Vitals has permission to read this file with no special permissions.

This would be a one time load of the file and stored in memory. I know that this file supports other things like thresholds and conversions, but for now labels would be nice. The goal is to keep the changes as minimal as possible. Please note that I've pushed some changes to both develop and main that you'll want to use.

Thank you for the feedback. I agree that issuing a subprocess command is not great. It's possible to do asynchronously, that would be better. I'll follow your lead anyway.

I have tested parsing of /etc/sensors3.conf, for labels only it's straightforward. My problem is that I don't know how to link a "chip" from that configuration file to a "device" in the hwmon sysfs tree.

I will take care of merging your commits to my branch. Thanks again.
