Per Radxa here, it is possible to obtain CPU temperature via "sudo cat /sys/class/thermal/thermal_zone0/temp".

But the following paths do not exist on Armbian 23.05.1 Bookworm with Linux 6.1.30-rockchip64:

• /etc/armbianmonitor/datasources/soctemp
• /sys/devices/virtual/thermal/thermal_zone0/temp

Running armbianmonitor -M, also does not show the temp:

Time CPU load %cpu %sys %usr %nice %io %irq C.St.
22:29:52 408 MHz 0.02 0% 0% 0% 0% 0% 0% 0/6

 

Same problem here. No thermal_zone on Rock Pi S.

You're probably running the same DTB without a properly wired thermal-zones.

Good. I thought it must be related to the device tree but I'm using the official Armbian Bookworm image for Rock Pi S: Armbian 23.8 Bookworm CLI (https://www.armbian.com/rockpi-s/)

How to fix?

So I tried the official Radxa image for Rock Pi S and thermal zone works correctly there. So it is definitely a bug in Armbian but I guess I cannot expect any support here.
