Huawei Sun2000 & ioBroker via JS script funktioniert

Alex Warkentin

@atari
Das Abfrageintervall kannst du in der letzten Zeile des Scripts in ms einstellen. Dein Problem liegt wohl aber weniger am Intervall (dann kommt zwischendurch eine Warnung, dass das Gerät beschäftigt ist), sondern, dass das Script beim Verlust der Modbus-Verbindung diese nicht wieder automatisch aufbaut.

@alex-warkentin
Danke für deine Antwort. Soweit funktioniert jetzt alles.
Gibt es eigentlich eine Möglichkeit die Infos auszuschalten denn so sehe ich im Log ja nur mehr diese von dem Skript.
Danke für eure Hilfe

@juggi1962

Bin auch nicht so fit in js..
ändere mal die Einstellung für den Speicher.

zum Bsp.:
const BatteryUnits = [0, 0];

Edit:
Deinem Log zufolge bekommst Du keine Daten von der Anlage.
Hast Du in den Kom.einstellung des Wechselrichters den ModBus
aktiviert?

Danke für deine Antwort. Soweit läuft jetzt alles

@juggi1962
Suche mal im Script mit STRG + F nach "console.log" und setze überall, wo dich die Information nicht interessiert "//" vor die Zeile.

@alex-warkentin
Super Danke, werde ich gleich probieren

@kachel

Vielen Dank für das Script und Deine Arbeit !

Wie kann ich den Abfrage Intervall nach einem Durchlauf verzögern
oder nur einmal pro Minute oder alle 5 Minuten starten lassen?
Ein Timer mit: von Uhrzeit bis Uhrzeit alle x Minuten wäre auch super.

Momentan bekommt das Script irgendwann im Laufe des Tages keine
Daten mehr und erzeugt nur noch Fehlermeldungen.
In diesem Fall hilft nur: das Script stoppen und nach einigen Minuten
wieder starten.

Edit:
Würde Dir für Deine Arbeit 'nen Kaffee oder 'n Bier spendieren.

Ich habe leider das selbe Problem. Eine Weile läuft alles bestens und dann nur mehr Fehler.
Neustart und es läuft wieder ein Weilchen.

Ich habe das selbe Problem.
Ich habe eine LAN Verbindung also sollte fie Verbindung bleiben, oder verstehe ich da was falsch? was kann man da machen

@juggi1962 Poste mal die Logs, wenn der Fehler auftritt

Hier ist das Script, was ich für mich angepasst habe. Achtung! Ich habe die Batterie und andere für mich uninteressante Sachen rausgeschmissen und die Namen von Variablen und Funktionen angepasst. Für die Neuverbindung nach Verbindungsabbruch brauchst du die Zeilen 18 - 27 , 107-122 und 235 -237

Guten Morgen soweit läuft es mal, aber kann es sein, dass bei
Solarpower Huawei Inverter 1 AccomulatedEnergyYield und
Solarpower.Huawei.Inverter.1.DailyEnergyYield
das Komma fehlt, denn der Tägliche Ertrag wäre schön aber nicht war :-)
kann man das irgend wie ändern?

Guten Morgen soweit läuft es mal, aber kann es sein, dass bei
Solarpower Huawei Inverter 1 AccomulatedEnergyYield und
Solarpower.Huawei.Inverter.1.DailyEnergyYield
das Komma fehlt, denn der Tägliche Ertrag wäre schön aber nicht war :-)
kann man das irgend wie ändern?

Diese Werte habe ich mir noch gar nicht angeschaut. Hier fehlt im Script (Zeilen 193 und 194) tatsächlich der Multiplikator.

ForceSetState("Solarpower.Huawei.Inverter." + id + ".AccomulatedEnergyYield",   GetU32(globalDataBuffer[id-1], 32106) / 100,          {name: "", unit: "kWh"});
    ForceSetState("Solarpower.Huawei.Inverter." + id + ".DailyEnergyYield",         GetU32(globalDataBuffer[id-1], 32114) / 100,          {name: "", unit: "kWh"});

Zu deinem Hauptproblem: Ich bin mir aktuell nicht ganz sicher, ob die Wiederverbindung im Script korrekt funktioniert. Ich habe bisher nur das Netzwerkkabel des ioBrokers für 10 Sekunden gezogen und das machte ihm nichts aus. Aber die Meldung, die bei einer neuen Verbindung geloggt werden sollten, kamen nicht. Daher kann es gut sein, dass client.isOpen vielleicht gar nicht so funktioniert wie erhofft.

@alex-warkentin
Danke für deine Bemühungen und für die Richtigstellung der Multiplikatoren :+1:
Kannst du das mit dem client.isOpen vielleicht testen und verbessern, das wäre echt super.
Ich kenne mich leider mit JS gar nicht aus.
Danke im Voraus, Gruß Jürgen

@juggi1962
Ich bin aktuell beruflich ziemlich eingespannt, aber mich interessiert das auch. Ich werde das bei Gelegenheit mal genauer anschauen.

isOpen soll laut Doku eigentlich ein Funktion an. Wird aber als solche nicht zur Verfügung gestellt und ist sonst auch immer true. Probiere bitte dein Script mit folgendem Snippet ab Zeile 197 zu überschreiben. Nun frage ich den ErrorCode nach null ab und reconnecte dann.

function ReadRegisterSpace(id, address, length) {
    client.setID(modbusID[id-1]);
    client.readHoldingRegisters(address, length, function(err, data) {
        if (err) {
            if (err.modbusCode == null) {
                console.warn("Lost connection to client. Trying to reconnect...");
                ConnectModbus();
            } 
            else console.warn("Error received reading address " + address + " from id: " + modbusID[id-1] + " with error: " + modbusErrorMessages[err.modbusCode]); 
        }
        else
        {   
            console.debug("Read data from id/address " + modbusID[id-1] + "/" + address + "\nData is: " + data.data);
            for(var i = 0; i < length; i++)  {
                globalDataBuffer[id-1][address+i] = data.data[i];
            } 
        }
    });
}

function ProcessData() {
    //console.log("Processing new data...");
    for(var i = 1; i <= modbusID.length; i++) {
        ProcessInverterStatus(i);
    }    
    ProcessPowerMeterStatus();
    //console.log("Processing done!");
}


// -------------------------------------------------------------------
// This is the main function triggering a  read via modbus-tcp every two seconds.
// Processing of data is triggered as soon as one complete set of registers is copied.
var triggerprocessing = 0; 
var currentinverter = 1;


setInterval(function() {
    if(triggerprocessing == 1) {
        triggerprocessing = 0;
        ProcessData();        
    }      
   
    //console.log("Triggering read of inverter " + currentinverter + " at address " + registerSpacesToReadContinuously[registerSpacesToReadContinuouslyPtr][0] + " with length " +  registerSpacesToReadContinuously[registerSpacesToReadContinuouslyPtr][1]);
    ReadRegisterSpace(currentinverter, registerSpacesToReadContinuously[registerSpacesToReadContinuouslyPtr][0], registerSpacesToReadContinuously[registerSpacesToReadContinuouslyPtr][1]); 
    registerSpacesToReadContinuouslyPtr++;               
    if(registerSpacesToReadContinuouslyPtr >= registerSpacesToReadContinuously.length) {
        registerSpacesToReadContinuouslyPtr = 0;
        currentinverter++
        if(currentinverter > modbusID.length){
            currentinverter = 1;  
            triggerprocessing = 1;                    
        }
    }     
}, 3000);

Du solltest aber trotzdem versuchen zu ergründen, warum die ständigen Verbindungsabbrüche kommen. Falls möglich vielleicht das Ethernet-Kabel tauschen.

juggi1962

@alex-warkentin
Hallo und noch mal danke für deine Bemühungen.
Leider gibt es immer noch die selben Fehlermeldungen, bis jetzt immer mal einzelne,
mal schauen ob es wieder dauerhaft wird.
Ich habe jetzt für eine Stunde einen Ping laufen lassen und hatte beim Ping keine Abbrüche aber im Skript 10 Fehler.
Lankabel wurde vorher gegen ein neues getauscht.
Hmmmmm komisch :disappointed:

Naja, jetzt müsste die Fehlermeldung "Lost connection...." lauten. Und danach die Verbindung neu aufgebaut werden. Dann funktioniert das Script erwartungsgemäß.

Wie ist es denn mit deiner ioBroker Hardware? Kann es sein, dass hier die Abbrüche stattfinden?

juggi1962

@alex-warkentin
Die Fehlermeldung Lost connection... kommt nur wenn ich das LAN Kabel ziehe.
Mein Raspberry und IoBroker laufen ohne Aussetzer.
Diese Fehlermeldungen auch mit 32000 kommen immer mal wieder, hören aber dazwischen wieder auf.
Gruß Jürgen.

Error received reading address 37100 from id: 1 with error: undefined

Alex Warkentin

@juggi1962
Modbus hat einige Fehlercodes. Nur einige davon werden von dem Script auch in Klartext übersetzt. Ich weiß auch nicht, ob das Plugin was wir da verwenden, die ganzen Fehlercodes behandeln kann. Vielleicht hast du ja gar keine Verbindungsabbrüche, sondern der Errorcode liegt einfach außerhalb des Arrays der Messages.

Gehe mal zu der Zeile wo die Warnung generiert wird und dort ganz ans Ende und lösche modbuserrormessages und die eckigen Klammern um den errorcode, sodass nicht die oben definierten Messages, sondern der Fehlercode selbst dargestellt wird. Vielleicht kommt da ja ne Meldung, die man besser analysieren kann.

juggi1962

@alex-warkentin
Danke, hab das gerade gemacht und werde es heute beobachten.
Wenn ich weiterhin lästig sein darf geb ich dir falls was daher kommt Bescheid.
Gruß Jürgen.

So nun sind die ersten Fehlermeldungen gekommen und zwar

Error received reading address 37100 from id: 1 with error: 6
Error received reading address 32000 from id: 1 with error: 6

Gruß Jürgen
