Open DTU (Hoymiles) NodeRed MQTT WR Modul
Verfasst: Mo Okt 17, 2022 9:55 am
Edit 19.10.2022 - Aktueller Flow:
Hi,
ich bräuchte mal etwas Hilfe um an die OpenWB über WR2 MQTT die Daten korrekt zu senden.
Ich habe mehrere Microwechselrichter von Hoymiles. Diese lese ich über OpenDTU aus. https://github.com/tbnobody/OpenDTU
Deren Daten landen über MQTT bei mir im HomeAssistant. Die Ertragsdaten bekomme ich für jeden Microwechselrichter einzeln. Um nun der OpenWB die Daten korrekt zu liefern muss ich diese also erstmal Summieren. Das wollte ich nun mit NodeRed als HASS AddOn machen. Das klappt aber nicht ganz zufriedenstellend.
Hier ist das was ich grade im NodeRed mache.
Die Leistung wird relativ gut übermittelt. Mir ist aufgefallen, dass manchmal die Summe abweichend zu den Einzelwerten ist aber das ist dann nur relativ kurz. Hier geht es eher um Feintuning.
Probleme bereitet mir der Gesamtertrag. Summiere ich das Ganze genau so wie den Ertrag bekomme ich völlig abweichende Werte in der OpenWB als das was ich sende. Zudem rutscht plötzlich der Gesamtertrag der OpenWB ins Minus. Und das obwohl da noch 3 SMA als WR1 konfiguriert sind und die liefern deutlich mehr als die Hoymiles. Ich bin nun 26kwh im Minus obwohl ich nur ein paar Wh über MQTT übermittelt habe.
Man soll es ja Float schicken. Daher habe ich nun ein FloatModul von nodeRed genommen. Aber da kommen nur irgendwelche ganz eigenartige Werte raus ohne Sinn. Ich bin mir nun also absoult unsicher wie ich der OpenWB die Gesamtertragsdaten für WR2 senden soll damit auch plausibel gezählt werden kann.
Eventuell hat hier schon mal jemand etwas ähnliches gemacht und kann helfen?
Grüße
Dirk
