GL-X300B: How can I get the CPU temperature?

No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Is there any way to get the temperature?

Try this one:

awk '{print $1/1000}' /sys/class/thermal/thermal_zone0/temp
3

awk: /sys/class/thermal/thermal_zone0/temp: No such file or directory

4

Could you please run
ls /sys/class/thermal/
and
ls /sys/class/thermal/thermal_zone0

5

ls: /sys/class/thermal/: No such file or directory

root@GL-X300B:~# ls /sys/class
bdi gpio misc power_supply spi_master
block ieee80211 mtd ppp tty
devcoredump leds net scsi_device ubi
extcon mdio_bus pci_bus scsi_disk usbmisc
firmware mem phy scsi_host watchdog

Firmware version is: 3.217

In that case, there appears to be no way to monitor the temperature.
But maybe some GL staff knows more about it.

I updated the firmware to version 4.5.16 and now the directory “/sys/class/thermal/” exists but is empty.
