Bei der Suche nach einer Möglichkeit, die Parameter des Wirtsystems des FHEM-Servers zu überwachen, bin ich auf den SYSSAT-Modul und die RPiUtils-Bibliothek gestossen.

Sysstat liefert die Systemauslastung, mit RPiUtils können viele andere Werte erfasst werden. Allerdings ist dafür ein zimliches Gewusel von Dummy-Devices und AT-Befehle notwendig.
