UPDATE 31.10.: Amazon Alexa - ioBroker Skill läuft aus ?

[Xanon]

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

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.

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)

[spooky82]

@chris_b

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

@chris_b

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

[Chris_B]

@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:

1. Am Ende jedes Tages die aktuellen Werte in ein File schreiben, zur Analyse in bspw. Excel.
2. Den Tagesverbrauch ausgeben (wie im Huawei Portal)
3. Den Modbus-Trafic verringern (bspw. Nachts)
4. Mein UI verbessern
   Hier mein aktuelles UI und das Skript.

@chris_b

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!

Gruß

[anno171986]

@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.

VG

[Chris_B]

@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

[anno171986]

@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

@chris_b Hi, ich habe diesen Thread gerade gefunden und das Script bei mir installiert. Wenn ich es starte, erscheinen nach einigen Sekunden Warnungen, die dann zyklisch wiederholt werden

In den Objekten erscheinen Werte, die zunächst grün sind, dann rot werden. Auch scheinen die Werte falsch formatiert zu sein?

Hab ich irgendwo einen Fehler in der Konfiguration gemacht?

Der Battery Overview scheint ja auch nicht zu klappen.
Habe eine SUN2000 mit 10kWh Speicher in 2 Modulen.. Ein Tipp wäre super!
Und: VIELEN DANK für die Arbeit, die da drin steckt! :)

[Chris_B]

@road_runner31 Hallo. Kurz ein paar Hinweise. Das ursprüngliche Skript ist nicht von mir, siehe ganz oben in diesem thread. Ich habe das Skript abgeändert, Fehler korrigiert und bin am erweitern. Was mir einfällt:

1. Im Javascript Adapter muss (!!) Modbus-Serial eingetragen sein:
   
2. Prüfe Deine IP Adresse.
3. Die PowerMeterID musst Du ausprobieren, scheint aber meist 0 zu sein.
4. Du schreibst, dass Deine Luna2000 2 Module hat, dann solltest Du auch entsprechen BatteryUnits = [[2, 0]]; schreiben.
5. Einige Werte unter 'Derived' sind erst nach dem erstamligen Überschreiten von Mitternacht sinnvoll gefüllt.

Mehr fällt mir gerade nicht ein. Gruss

[road_runner31]

@chris_b Hallo, danke für die Antworten. Die Anzahl der Module hab ich schon korrigiert. Die IP-Adresse stimmt, es sind ja auch ein paar Werte korrekt (bspw. das Modell). "modbus-serial" ist auch eingebunden.
Ich lasse das Script jetzt mal laufen, trotz Fehlern, mal schauen was morgen drinsteht..
Viele Grüße!

[Chris_B]

@road_runner31 Ich glaube aber, dass Du noch ein anderes Problem hast bei Deiner Anlage. Die Sache mit den Werten nach Mitternacht kann das nicht sein, das ergibt nur am ersten Tag für ein paar Werte sinnlose Zahlen, aber keine Fehlermeldungen.
Ich glaube Deine Sun2000 ist nicht ansprechbar. Anwortet sie auf ein PING? Das würde ich einmal als nächstes checken. Gruss

[exel]

@road_runner31 Ich kann das Verhalten bestätigen, sieht bei mir genauso aus.
