Temperature

[hdk]

This one seems to read the battery temperature, which doesn't seem to have a proper sensor. Try this:
cat /sys/class/thermal/thermal_zone0/temp | echo Zone 0: `awk '{print int($1/1000)}'`

rock64@pinebookpro:~$ cat /sys/class/thermal/thermal_zone0/temp | echo Zone 0: `awk '{print int($1/1000)}'`

Zone 0: 32
