GL-A1300 CPU temperature

Is there a way to see the CPU-temperature of a GL-A1300 (Slate Plus)?

Try this one:

Thank you for the link, this was my first try. But I didn’t succeed:
awk: /sys/class/thermal/thermal_zone0/temp: No such file or directory

What am I doing wrong?

I found the directory, but there seem to be no values.

Edit: the command seems to work with my SFT1200 (Opal).

Maybe the A1300 does not have the necessary thermal sensors, idk.
