<![CDATA[wifimanager over 90% CPU usage - Omega2p]]>Seems the wifimanager process is the culprit for high CPU usage and Omega2 getting very hot (as reported by others).

In my omega it was constantly using over 95% CPU (see attached) and the omega LED kept blinking.

Disabled it from starting in /etc/init.d and now Omega runs cool. LED is also steady.

@György-Farkas I'm not sure I understand the question. Are you asking how to disable wifimanager?

If so this can be done through

/etc/init.d/wifimanager stop
/etc/init.d/wifimanager disable

I am watching my O2+ via serial terminal and / or via ssh (connecting to Omega's Wifi AP).
I can not run wifimanager and top at the same to see that nice

%CPU
99 % {wifimanager}

How did you do that?

OK. A shell script might help me a lot 😉

I see. On my Omega2 wifimanager was set to run on boot, so I didn't start it manually.

I think the problem with wifimanager is that if it is run manually it never completes (as others also found in another thread).
