… völlig falscher Forenbereich, da es aber nur für IPS@RasPI funktioniert …
Um die Daten der Temp / Core / Mem des RasPI anzuzeigen, habe ich folgendes Skript angepasst. Besonders liebevoll gestricjt ist es nicht, Variablen.IDs müsst ihr selbst anpassen. Man kann dann etwas besser sehen, wenn der RasPI in die Knie geht. Skript stammt von http://derkev.in/rpisysinfoscript/
