Huawei Sun2000 & ioBroker via JS script funktioniert

bahnuhr

@alle

Wäre es möglich das aktuelle Script zentral, z.B. in #1 abzulegen.
(oder ist dies nicht vom TE)

Ich habe momentan nicht mehr den Überblick wo ich das aktuelle finde.

Danke.

Ne, das war ein Platzhalter.
Du kannst " + irgendEineVariable" z.B. an einer Stelle durch " + RegToReadPtr" ersetzen, so dass du die Nummer der aktuell ausgelesenen Werte siehst (die von RegToRead), oder auch weg lassen und statt "hier bin ich - " auch Zahlen oder auch sonstwas hinschreiben, so dass du im Log unten weißt, wo du gerade bist im Code.

Ok, habe angefangen:

Und

Das Ergebnis im Protokoll so aus:

Ideen?

@leonundjulie
Äh, du hast doch keine Batterie?

Richtig. Da es mit der Version 2 und von mir heraus kommentierten Batt-Zeilen nicht funktionierte, habe ich die gestern veröffentlichte Version zunächst einmal unverändert gelassen …. muss wohl wieder Zeilen herauskicken … wird dann auch übersichtlicher

also

const BatteryUnits = [[0]];

und

const RegToRead = 
[ [32000, 116],   // inverter status -                            read fast
//  [37000, 68],    // battery information -                        read fast

];
const RegFast = 2;      // number of register spaces to read fast (must be < RegToRead.length)

und (hast du Optimizer?)

function ProcessData()

 {
    //console.debug("Processing new data...");
    for ( var i = 1; i <= ModBusIDs.length; i++)
    {

        //ProcessBattery(i);

    }

... aber Fehlermeldung beim Lesen von Register 30000 sollte nicht dauerhaft kommen

Hallo,
ich habe eine Frage zu folgendem Hinweis im Script:

// Enter your battery stack setup. 2 dimensional array, e.g. [[3, 2], [3, 0]] means:
// First inverter has two battery stacks with 3 + 2 battery modules
// while second inverter has only one battery stack with 3 battery modules

dort steht: 1. Inverter mit 2 stacks und 2 modules, also [3,2]
und: 2. Inverter mit 1 stack und 3 modules; müsste dies dann nicht [1,3] heißen ?

Irgendwie passt dies nicht so richtig, oder ich versteh es nicht.

Habe mal eben zwischen Tür und Angel Deinen Ansatz umgesetzt - leider nicht ohne Fehler …. Kann denen aber erst heute Abend nachgehen.

@leonundjulie
Mit dem Script direkt hat das augenscheinlich nichts zu tun.
Ich bin da erst mal raus.

leonundjulie

Ich habe mal eine ganz andere Spekulation: welche Software Versionen habt Ihr den so auf dem WR respektive auf dem Dongle? Ich frage, weil - wenn es nicht zur erneuten Verschiebung kommt - am kommenden Donnerstag vom Solateur EnPAL ( ) ein neuer WR eingebaut wird (der alte fährt bis 150 Resets am Tag wegen „Isolationsfehler“ -> ich glaube zwar, dass die Fehler eine andere Ursache haben, aber die können das aus der Ferne ja besser beurteilen ).

Wie dem auch sei, ich will natürlich dafür Sorge tragen, dass dann auch die richtige Software auf den HUAWEI Komponenten drauf ist.

R4

@leonundjulie
Für Versionsinfos auch hier schauen, man muss nur bisschen suchen...

Beim SDongle sind V100R001C00SPC133 bzw. V200R022C10SPC107 derzeit aktuell.

Guten Tag zusammen,

ich bräuchte mal ein kleines bisschen Unterstützung. Ich möchte das Skript von @Chris_B etwas abspecken. Ich brauche das Zusammenrechnen der Verbrauche zum Beispiel nicht.

Arbeitet das Skript nicht mehr. Ich bekomme aber kein Protokoll und auch keine Daten in den Objekten. Aber was genau fehlt mir, damit ich nun die Daten bekomme?

@leonundjulie
Für Versionsinfos auch hier schauen, man muss nur bisschen suchen...

Beim SDongle sind V100R001C00SPC133 bzw. V200R022C10SPC107 derzeit aktuell.

Was soll ich sagen - es läuft. Warum? Zunächst habe ich mir die aktuellen Software Paketen für den WR und den Dongle aus dem Netz gezogen.

WR: alles aktuell

sDongle: um sich einloggen zu können -> SDongle heraus, nach 2 Minuten wieder rein, eingeloggt …. Software ist aktuell

Zurück zum IOBROKER, Skript gestartet …. , alle 5 Sekunden kommen Werte.

Jetzt hoffe ich nur, dass das auch so anhält.

Dank gebührt allen, die geholfen haben - Merci. Natürlich bleibe ich dabei, warte aufs nächste Update des Skriptes und teste gerne weiter mit

Nachtrag vom heutigen Sonntag: da ich erst heute Zeit finde, kann ich erst jetzt als Nachbrenner einbringen, das ich oben vergessen habe zu erwähnen, dass ich in meinem EnPAL-Konstrukt während des ganzen Testens die LAN-Verbindung zwischen dem Huawei S2000 und der EnPAL Box herausgezogen hatte. Kaum war der LAN-Stecker wieder in der Buchse, hat das Skript keine Werte mehr ausgeworfen. Dies führt zur Annahme, dass der SDongle - wenn WLAN und LAN gleichzeitig eingesteckt sind - (oder vielleicht der Wechselrichter selber) einer LAN-Verbindung Priorität gibt bzw. WLAN keine weiteren Zugriffe erlaubt.

Auch der in anderen Foren beschriebene Zugriff via WLAN funktioniert via dem WLAN des WR (Netz mit geringer Reichweite und nicht via WLAN des Dongles), wenn die LAN-Schnittstelle des SDongles verwendet wird.

Also werde ich jetzt mal versuchen meinen PI an das LAN der EnPAL-Box anzuschließen, ein Port ist noch frei :-), und mich wieder melden wenn ich das IP-Routing im Griff habe. Gemäß meiner obigen These müsste dann endlich gehen.

R4

@hussi
?
Du entfernst Funktionen wie SolarPowerLogging() und vor allem ProcessData() und wunderst dich, dass es kein Loggingprotokoll mehr gibt und die SW nicht mehr tut?

Bitte lass das Zeug drin, wenn du nicht weißt, was es tut.
So viel CPU Zeit benötigt das jetzt auch nicht...

(ok,

schedule("59 23 * * *", function () {...}

kannst du rauslöschen, wenn du keine Logdatei willst.)

hussi

@r4 Nee ich wundere mich nicht. Ich weiß ja nicht was ich tue. Brauche aber die Berechnungen nicht und habe daher gedacht ich kann sie so rausnehmen.

Frei nach dem Gedanken: Je schmaler, je besser.

Chris_B

@hussi Ich würde echt nicht raten, solche Dinge rauszunehmen. Nicht weil es (teilweise) Dinge sind, die ichgeschrieben habe, aber einfach Dinge löschen bringt wenig, auch wenn Du gewisses nicht brauchst. Diese Berechnungen brauchen ja keine relevante Rechenleistung und dadurch wird das Skript nicht wirklich 'besser', in einer Form, die Du bemerken würdest... Gruss

leonundjulie

@chris_b und @R. Guten Morgen Euch Beiden. Ich habe eine Verständnisfrage zum Konzept des Skripte. Die Frage kam auf im Rahmen der Analyse der bei mir Installierten EnPAL-Topologie und der Tatsache, dass man ganz am Anfang des Skriptes die ID des SmartMeters angibt, die dann beim Ablauf des Skriptes, also beim Abfragen der verschiedenen Werte, bei der Abfrage des SmartMeters verwendet wird.

Warum wird die Abfrage an das SmartMeter und nicht an den WR gerichtet? Die verwendeten Register-Adressen gehören doch zum Wechselrichter und nicht zum SmartMeter

hussi

@chris_b Hab ich verstanden. Dann lasse ich alles so. Wie gesagt: Dachte je schmaler, je besser.

Danke für Deine Tolle Arbeit!

Edit:

Wenn ich nur eine Batterie habe, mache ich das dann so:

const BatteryUnits = [[1, 0]];

?

@leonundjulie sagte in Huawei Sun2000 & ioBroker via JS script funktioniert:

Auch hier: ?
Das Script liest nur die ModBus-Daten des WR ein.
Der WR selbst stellt die Smartmeter-Daten bereit (liest die von dort selbst ein).
Und mit

const PowerMeterID = 0;

stellst du auch nicht die ID des PowerMeters ein (der hat gar keine), sondern

// On which Modbus-ID can we reach the power meter? (via Sun2000!)

hier also wird der erste Eintrag im Array

// Enter the Modbus-IDs of your Sun2000 inverters here (example for two inverters): const ModBusIDs = [16, 1];
const ModBusIDs = [1];

verwendet, was die Modbus-ID des WR ist, an dem der PowerMeter angeschlossen ist.

Ja, auch hier … da die Node-Red-Variante bei mir nicht laufen will - aber jetzt kann ich es ja vielleicht erklären (s.o.).

Danke für die Antwort. Auch den Anteil habe ich jetzt verstanden. Und ich dachte schon die Antwort dafür zu haben, warum in der Zeit - als ich die LAN-Strecke zwischen SUN2000 und EnPAL-Box unterbrochen hatte - im SUN2000 keine Meter-Werte mehr auftauchten. Irgendein Geheimnis steckten in dieser EnPAL-Topologie immer noch

Chris_B

@leonundjulie Der Antwort von @R4 habe ich nichts hinzuzufügen - genau so ist es Ich würde auch das im Skript nicht verändern, deckt den Fall von 2 WR ab. Ich weiss nicht, wie häufig das ist, aber es ist allgemeiner...
