Hallo
Hier mein aktueller Stand des Skripts. Bitte beachten:
- Das Skript ist noch NICHT fertig. Ich werde in den nächsten Tagen noch weitere Verbesserungen vornehmen.
- Unter client.connectTCP("192.168.0.0", { port: 502 }); die eigene TCP-IP Adresse des INverters angeben
- Verwendung des Skripts auf eigene Verantwortung.
Das Skript erzeugt neu noch zusätzliche Variable unter Solarpower.Derived.XXX. Die Beschreibung der Variable ist meist selbsterklärend.
Ich werde in den nächsten Tagen und Wochen noch folgendes erweitern:
- Am Ende jedes Tages die aktuellen Werte in ein File schreiben, zur Analyse in bspw. Excel.
- Den Tagesverbrauch ausgeben (wie im Huawei Portal)
- Den Modbus-Trafic verringern (bspw. Nachts)
- Mein UI verbessern
Hier mein aktuelles UI und das Skript.
