Mmm its possibly some waiting loop for commands. I wouldn’t worry too much if it’s under 25% (which would mean it is taking the 100% time of a core) and you don’t get a yellow square on the corner (throttled cpu speed because a temperature warning).
I see mine around 4.5% on idle and as high as 22% when precaching. You could also try disabling some unused services like RemotePi Board, Hyperion, samba, etc if you have any issue
The chart comes from Jeedom. I have another raspberry with Jeedom on it.
Jeedom is en home automation operating system.
@videotecaCNSU . Ok for the loop. I have disabled the service I don’t need.
When my server is off the temp of rasplex is low (53°C).
When it is on but I don’t use rasplex the temp is high (60-70°C).
When I watch something, the temp goes down and stay at 54°C.
