Huawei Sun2000 & ioBroker via JS script funktioniert

[Alex Warkentin]

@juggi1962
Ich nutze eigentlich nur die Infos von Smart Meter. Die active power dort zeigt dir den aktuellen Überschuss oder Bezug. Nagel mich daher nicht darauf fest, aber ich denke Active Power ist das was der WR aktuell in liefert und Input Power müsste das sein, was von den Modulen in den WR geht

Okay, Danke

Hallo zusammen,
gerade ist der SUN2000 in Betrieb gegangen mit 10kwh und 11kwp
Was ist denn der aktuelle Stand hier ? hat es jemand am Laufen?

@baumiliciousnessss
Ja, ich habe das Skript von @Alex-Warkentin und das funktioniert jetzt.
Er hat das Original Skript ein wenig abgespeckt und den Batterie Teil rausgenommen da er und ich keine Haben.

Die Fehler die bei mir gekommen sind, sind jetzt fast weg, seit ich die Abfragezeit auf 4000 ms geändert habe.
Ich hoffe ich konnte helfen, Gruß Jürgen

@alex-warkentin
Mir ging es nicht um den eigentlichen Abfrageintervall, mit dem habe ich schon experimentiert.
Mein bestes Ergebnis habe ich bei 3333ms erhalten, hierbei treten nur sehr sporadisch Fehlermeldungen
wegen "...Busy..." auf und ich erhalte dennoch ca. 2 mal pro Minute neue Daten.

[Alex Warkentin]

Funktioniert das Script bei euch noch? Seit heute bekomme ich fast bei jedem Abruf die Fehlermeldung, dass der Port nicht geöffnet ist.

[severendis]

@thomas42

Hallo Thomas!

Danke für die Beschreibung, mit der ich das Script zum laufen bekommen habe.
Aber etwas ist bei Dir scheinbar anders.
Du schreibts, das du 2 WR hast und die mit der Modbus ID 1 und 2 ansteuerst.
Hast Du dann an jedem WR einen Dongle dran?

Bei mir hängen 2 WR im Verbund an einem Dongle.
Ich habe somit nur eine Modbus Adresse (die 1)

Bisher arbeite ich über NodeRed (was mir zu langsam und speicherintensiv ist). Da kann ich die Register von beiden WR abfragen.
Hierfür gibt es eine "Unit-Id"
So frage ich dort z.B. mit
32064 Unit-Id 1 die PV Input Power des ersten WR ab
32064 Unit-Id 2 die PV Input Power des zweiten WR ab

Das kann ich aber in diesem Script nicht finden und somit nur einen WR auslesen.

Wie sind die WR bei Dir angeschlossen?

[OliWit82]

Hallo zusammen.

Vielen Dank das Script läuft super.

Hat vielleicht jemand die Adresse für die Last vom Haus?

Danke

[OliWit82]

Kann man die Werte abfragen?
Oder muss man dich durch ein Script selber errechnen?

[badsnoopy667]

@oliwit82
Die Werte kann man nicht direkt abfragen und müssen berechnet werden.

Beispiel

Oh, sehe gerade, mein Script ist gar nicht für die kWh Werte. Damit berechne ich erstmal Verbrauch, Bezug, etc. Aber diese Werte kann man dann ja aufsummieren über den Tag.

[OliWit82]

@badsnoopy667

Danke.

Gibt es da vielleicht schon ein fertiges blockly?

[badsnoopy667]

@oliwit82
Das sollte sich mit dem sourceanalytix Adapter am einfachsten realisieren lassen.

Die Fehler die bei mir gekommen sind, sind jetzt fast weg, seit ich die Abfragezeit auf 4000 ms geändert habe.
Ich hoffe ich konnte helfen, Gruß Jürgen

Hallo, habe auch diese Skript genommen und funktioniert bei mir auch.
Nur habe ich noch eine LUNA2000 Batterie mit 10kWh und würde die gerne mit einbinden.
Kann mir einer sagen was ich noch mit einfügen muss, damit der Speicher mit drin ist?
Danke!

[Alex Warkentin]

Du solltest dann das Ursprungs-Script von Kachel aus dem ersten Post nehmen und beide ggf. kombinieren.

[g.polat]

Hallo zusammen,
habe nun das Script ebenfalls zum laufen bekommen, habe jedoch einige Verständnisfragen.
Was ist der Unterschied zwischen:
javascript.0.Solarpower.Huawei.Meter.ActivePower und javascript.0.Solarpower.Huawei.Meter.ActivePower
Welche Datenpunkte muss ich für den Energiefluss nehmen betreffend: Hausverbrauch; Netzeinspeisung; Netzausspeisung?
Wäre für Hilfestellung dankbar, da die Werte aus der APP nicht mit den ausgelesenen Werten bis auf den Akku übereinstimmen.

Laut AP aktuell:
Produktion 4,79 KW
Batterie wird mit 2,47 KW geladen
Ins Netz gehen 1,96 KW
Ins Haus 0,35KW

Ausgelesen per Script:
javascript.0.Solarpower.Huawei.Inverter.1.ActivePower 1.249 KW
javascript.0.Solarpower.Huawei.Inverter.1.InputPower 4.42 KW
javascript.0.Solarpower.Huawei.Meter.ActivePower 260 W
javascript.0.Solarpower.Huawei.Meter.PositiveActiveEnergy 1.49 KW

Hallo, auch bei mir ist jetzt ein Speicher dazugekommen.
Ich habe wie du empfohlen hast auch das AnfangsScript genommen, allerdings fehlen mir die Kenntnisse alle Optimierungen wie z.B. (den täglichen Ertrag (DailyEnergyYield)) oder (die Zeit für Wechselrichter Shutdown / Start als Uhrzeit / Datum) nachträglich mit einzubauen und ich bekomme immer wieder Fehlermeldungen ins Log und weiss nicht wie ich Sie behandeln kann.

Wärst du oder vielleicht jemand anderes so freundlich und würde mir sein Skript welches den Batterie Speicher beinhaltet und optimiert / verbessert ist zur Verfügung stellen?

Vielen Dank

@Kachel
Ich habe Deine Skript auch bei mir implementiert (5KWp, 15 kWh Speicher).
Es läuft, ich hatte aber folgendes Problem bei meiner iobroker Installation: Die Funktion forcesetState() funktioniert bei mir nicht. Dadurch werden das erste Mal die Werte gelesen, danach aber nicht mehr, da nur createState() aufgerufen wird. Ich musste das folgendermassen abändern:

if (!existsState("javascript.0." + objectname))

D.h. ich muss beim Prüfen des State javascript.0 voranstellen.
Danach läuft das Skript gut.
Ich habe eine weitere Optimierung vorgenommen: Jetzt wird bei jedem Setzen der States geprüft ob der State existiert. Das ist ziemlich aufwendig. Ich mache das nun nur ein Mal pro 'Runde', und merke mir das in einer Variable. Dadurch wird nicht dauernd geprüft; spart etwas Processing Power...

@xanon Mach' ich in den nächsten 1-2 Tagen. Ich möchte noch ein paar weitere Verbesserungen vornehmen, dann stelle ich das Skript zur Verfügung.
