Since putting my tachyon in a case I've noticed it's felt quite warm - I'm sure it's well within spec but I can't seem to get to a simple high-level temperature reading in either particle-console or CLI. lm-sensors/hddtemp packages are included by default but the output of sensors only gives me battery temp/voltage/current readings.
Walking the thermal zones in /sys/class/thermal gives me 87 lines of output... amongst those I can see zones that are named things like modem-lte-sub6 and cpu-0-0-step .... any clues on useful/meaningful ones to check?
closest I can guess is
/home/particle/thermals.sh 2> /dev/null | grep -i uss
gpuss-0-step 51.0°C
gpuss-1-step 49.8°C
cpuss-0-usr 55.8°C
cpuss-1-usr 53.9°C
gpuss-0-usr 51.0°C
gpuss-1-usr 49.4°C
???
Hey Zedstarr,
I typically used 'sensors' to view temperature zones but it will output the same as /sys/class/thermal typically. in terms of which is important, that isn't something that is easy to document but I'll get it onto the list! The system automatically turns itself 'down' when it gets warm so the output is that CPUs will be restricted in CPU temperature and the modem throughput will be reduced all the way up to 100C operating temperature so there isn't much to worry about.
You can keep the temperature down by setting the cpu governors to change the behaviour and use hot plug to remove those cores - a lot more to that than I can write here quickly, but it all works 
Thanks
Nick.
sensors only outputs 5 zones for me - none of which are cpu/gpu, hence why I went looking in /sys/class/thermal

Looking into this - we use a script that we can open source here and will circle back!
I am also seeing 87 thermal zones (and 45 cooling devices). and then only 5 entries in sensors none of which are the CPU. Sensors was also not preinstalled and the thermals.sh script is not present.
Is it possible to at least get some indication of which zones are vaguely applicable
Just following up here - I’ll chase this down and get back! I had delegated but not followed up - my bad. Thanks!
Here’s the range of thermals I observe with Tachyon in a 3D-printed case (used hardinfo). Some negative and zero thermals values were removed from the list.
It would be good to match the thermal zones to the sensor types.
