Temperature monitoring

I do have collectd-mod-thermal installed but I don't see any temperature graphs. :man_facepalming:

I'm not really familiar with collectd, but you could check /sys/class/thermal just to see if there's anything in there (should be thermal_zone0 or something similar I think).

 OpenWrt 21.02.3, r16554-1d4dea6d4f
root@OpenWrt:~# cd sys
-ash: cd: can't cd to sys: No such file or directory
root@OpenWrt:~# /sys/class/thermal
-ash: /sys/class/thermal: Permission denied

Try ls /sys/class/thermal

root@OpenWrt:~# ls /sys/class/thermal

Hmm, if there's nothing there I assume (just a guess) your router doesn't have that capability, I had a similar problem with my linksys wrt1200 and the cpu frequency plugin, installed/enabled, but it just never showed up, the only thing in logs was that collectd couldn't find a cpu.

lm-sensors maybe?

As far as I know, none of the thermal-sensor kmods are included by default. You'll have to install the ones that are applicable for your SoC yourself.

How to do that?


Any link from where to download the kmods?

Are you sure that SoC even has a readable, built-in temperature-sensor in the first place? Most of the SoCs I've encountered do not have anything like that, since it's typically not a feature that's needed on consumer-grade routers/access-points.

I'm too tired to start digging into it myself and I've got a long drive ahead tomorrow.


No problem. I am in no hurry to sort this out. Just need the right directions.

Search if your device

(I doubt it).

A forum search might yield some useful information.

It doesn't.

Is it a MIPS processor?
