Hi, thanks for this great project. I'm not a developer, just an enthusiast... so go easy ;-). Anyway, I noticed a *** stack smashing detected ***: terminated error for the temperature component.

After a bit of printf debugging I've come to the conclusion that the char name[16]; declaration was the culprit - enlarging it to PATH_MAX allowed the component to run without crashing. On my system (some output from printf'ing):

from 1st esnprintf: /sys/class/hwmon/hwmon8/name
name is: ucsi_source_psy_USBC000:001

i.e. bigger than 16.

I've no idea if there is a "sensible" value for this, PATH_MAX seems excessive... maybe 48?

Do you think this is worth a change to your code... maybe I'm just an outlier! (thinkpad t470s running pop!_os) :-)

Cheers

may be you an outlier, but this bug must be fixed, so i'll fix it soon

Thanks, I see what you did there. Very sneaky. Indeed, it is fixed.
