How-To: Monitor SoC Temperature in Armbian at the Command Prompt
Recently, we wanted to monitor the SoC temperature on an Armbian system (ROCKPro64 in this case). Here's a quick one-liner that will allow you to do just that from the terminal (command line), outputting the time and the temperature once per second:
while :; do date; cat /etc/armbianmonitor/datasources/soctemp; sleep 1; done
Here's another method
watch -n 1 cat /etc/armbianmonitor/datasources/soctemp
This is a starting point to make temperature graphs using gnuplot or similar plotting programs.
Let us know how this works for you in the comments below.
