Hallo zusammen,

von meinem Growatt Wechselrichter erhalte ich via mqtt die aktuellen Systemdaten.
Allerdings nur solange der Wechselrichter auch produziert. Sobald die Sonne weg ist beendet der Wechselrichter die Kommunikation.
Aus diesem Grund erhalte ich am Ende des jeweiligen Tages noch eine Einspeiseleistung. Die Kommunikation bricht ab und die alten Werte bleiben in meinen Variablen erhalten.

Wie kann ich nun eine Art Timeout bauen, um bei Abbruch der Verbindung die Varialben auf beliebige Werte zu setzen.

Kommt also z.B. für eine Minute kein neues Telegramm, wird Einspeiseleistung und aktueller Strom der PV Module auf 0 gesetzt.

Im Anhang der aktuelle Flow in dem der JSON Inhalt in einzel Variablen zerlegt wird.
Vielleicht hat jemand eine Idee.

Gruß L.T.

@l-t-0 Einfach eine Trigger Node nehmen.

Ich hab Deinen Flow angepasst:

EDIT 17:45: In der Trigger Node war noch ein Fehler. ;)

muss natürlich angehakt sein. ;)

@mickym

Tiptop!!
Klappt in der Simulation wie gewünscht!
Unter echten Bedingungen kann ich leider gerade nicht testen, da ist zuviel Neuschnee auf den Modulen. Also konstant 0 Leistung :-(
