Huawei Sun2000 & ioBroker via JS script funktioniert

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...

Würdest du dein Skript hier zur Verfügung stellen?

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

Xanon

@g-polat Super Vielen Dank
Werde ich mal testen 👍

@chris_b
Ok, bin gespannt, was du noch aus dem Skript heraus zauberst.😊
Danke für deine Mühe.👍

@xanon
Hier schon einmal vorab mein aktueller Stand des Skripts. Dazu folgende Bemerkungen:

Das Skript ist noch nicht wirklich fertig. Ich komme aber erst am Wochenende dazu noch mehr Funktionalität einzubauen. Ich werde dann ein Update posten.
Die Sache mit createState() ist jetzt optimiert.
Neuer State: javascript.0.Solarpower.Dervied.PeakPower --> Zeigt den Max Wert der Panels an einem Tag an.
Neuer State: javascript.0.Solarpower.Dervied.BatteryOverview --> hier werden die % Werte jedes Battery Packs angezeigt, momentan fix für 3, sollte ich allgemeiner schreiben.

Ich werde am Wochenende weiter am Skript arbeiten und weitere Funktionen einfügen. Habe aber bis dann keine Zeit.

// From iobroker Forum: Huawei Sun2000 & ioBroker via JS script funktioniert

Hallo,

ich habe wohl ein Verständnisproblem.
Ich habe das Skript und den easee Adapter eingerichtet und alle Datenpunkte mMn korrekt gesetzt.
Das Laden geht jedoch nicht los.
Habt ihr Ideen?

Dankeschön

Chris_B

@spooky82 Sorry, aber da muss eine Verwechslung voliegen. Das von mir abgeänderte Skript oben ist für Huawei Sun2000 / Luna2000 Anlagen. Für das Auslesen der Anlagen via TCP / Modbus braucht man ausschliesslich das Skript, wie oben in diversen Beiträgen beschrieben.
Die Datenpunkte dafür befinden sich dann unter javascript.0.Solarpower....
Gruss

Chris_B

@chris_b Ich bin immer noch an der Anänderung des Skripts. Habe noch ein paar Fehler darin gefunden (falsche Skalierung der Werte). Ich brauche noch etwas mehr Zeit. Hier mein aktueller Stand für das UI (im Wesentlichen eine Nachbildung der Huawei App, aber, wenn ich dann fertig bin, so, wie es mir passt, und mit zusätzlicher Information.
(Dies ist ein noch fehlerhafter Zwischenstand)

@chris_b

Sorry, hast absolut Recht. Falsches Forum.
Danke dir!

Hallo Chris,

ich hätte starkes Interesse an deinem Script. Node-red ist leider nichts für mich ;-)

Meine PV-Konfiguration ist sehr ähnlich.

2 Strings (Ost/West), Powermeter, Optimierer und 1x Akkuturm mit 3x 5kwh Packs.

Würde mich freuen wenn du deine Arbeit mit uns/mir teilen würdest.

Grüße

@sweatchuck
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.

Vielen herzlichen Dank.

Deine Updates/Verbesserungen würde ich natürlich gerne auch bei mir integrieren.

Wenn ich bei der Entwicklung/Weiterentwicklung unterstützen kann (Tester etc.), lass es mich wissen!

@Chris_B Vielen Dank für dein Skript. Ich habe die vorletzte Vdersion und mit der Ausnahme der Datenpunkterzeugung läuft es auch gut.

Was mich ein bisschen ärgert ist, das Huawei anscheinend nicht alle Werte hier per API bereitstellt die man über die App sieht. Mich interessiert z.B. der Gesamtstromverbrauch am Tag. Kann man den aus den vorliegenden Werten berechnen, bin da noch nicht fündig geworden.

@sweatchuck
Mach ich gerne. Und Feedback, Testen sind sehr willkommen. Gerne würde ich mich auch in Sachen Sun2000 / Luna 2000 austauschen. Ich habe da noch einige Fragen. Ich melde mich am Wochenende. Bin gerade ziemlich mit Arbeit zu...
Danke und Gruss

Chris_B

@anno171986 Was meinst Du genau mit dem Problem der Datenpunkterzeugung?
Am besten Skript stoppen, Alle Datenpunkte löschen und Skript wieder neu starten.
Noch eine Bemerkung: Gewisse Datenpunkte werden erst 'sinnvoll' wenn einmal Mitternacht durch ist, da Differenzen zum Vortag benötigt werden...
Gruss

@chris_b
Vorweg: ich habe mein Skript noch nicht mit deinem neuen Stand vom 05.06.2023 aktualisiert.
Bei mir waren die Werte immer nur einmal aktualisiert worden, n achdem ich die Dtaenpunkte gelöscht hatte. Dann wurden sie per Skript einmaöl neu angelegt aber danach nicht mehr aktualisiert. Habe jetzt Teile ausgeklammert, damit funktioniert es:

function forcesetState(objectname, value, options)
//------------------------------------------------
// perform createState() only if variable does not yet exist, and perform the check via existsState() only once for each processing round
{  
    /* if (testCreateState == 0)
    {   if (!existsState(Folder + objectname)) { createState(objectname, value, options); }
        else                                            { setState(objectname, value); testCreateState = 1; }
    } else
    {   setState(objectname, value);
    }
    */
    setState(objectname, value);
}

Wieviel kwh du verbraucht hast, das kannst du auch nicht auslesen oder berechnen, richtig?

Chris_B

@anno171986 Ganz kurz: Bitte das neuste Skript nehmen. Das mit den Datenpunkten ist ein Problem des ursprünglichen Skripts (nicht von mir). Nochmals alle Datenpunkte löschen und das neuste Skript nehmen.
Den Verbrauch an einem Tag kann man rechnen. Das habe ich noch nicht gemacht, ist nicht sehr kompliziert, kommt vermutlich am Wochenende. Bitte etwas Geduld…
Ich möchte auch noch eine bessere Doku machen, damit es verständlich ist, was das Skript macht und kann. Ich möchte alle sinnvollen Werte der Huawei App in iobroker darstellen können…
Gruss
