Servus Arno.
Ich friere noch! Wir sind über Weihnachten und Neujahr im Oberallgäu. Noch keinen genauen Plan ob Portugal ja oder nein diesen Winter.
Ja, aber während der Schulung gibt es auch etwas zu trinken, du hast noch jede Menge gut bei mir!!!
Quatsch
Aber mit dem trinken können wir ab Ende März mal überdenken

Hey Arno, habe die Nodes etwas ergänzt und eine Seite zugefügt wo man die Spannungen eingeben kann. Musst die Seite nur in einen anderen Tab schieben, hier sind die jetzt im Info Tab. Viel Spas damit!

@ahtdf und weil ich grad dabei bin 
Idee war wie beim Strom eine Art “Time to go” für das Gas zu erstellen. Die Node speichert über 10 Tage den Gasverbrauch und erstellt eine “Reichweite” des noch vorhandenen Gas. Daten älter 10 Tage werden gelöschte. Die Node einfach hinter “Berechnung Füllstand” hängen. Ob sie richtig funktioniert kann ich erst später sagen, ist ja gerade erst erstellt worden.
