Huawei Sun2000 & ioBroker via JS script funktioniert

juggi1962

@alex-warkentin sagte in Huawei Sun2000 & ioBroker via JS script funktioniert:

@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.

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

Hab eh keine Batterie. Werde es gleich testen.

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

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!");
}

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]);

    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

badsnoopy667

@juggi1962
Ließt er denn den Rest der Register, oder geht gar nix?

37100 scheint laut Modbus Interface Definitions V4 eine Adresse des Energy Meters zu sein. Ist die dann unter der ID 1 ansprechbar, oder muss man da eine andere ID nehmen? Ist aber auch nur der "Meter status", also eig. relativ uninteressant würde ich sagen.
32000 hat als Typ "Bitfield16". Vielleicht wird hier nicht der richtige Typ abgefragt? Aber auch 32000 ist (aus meiner Sicht) ein relativ uninteressantes Register. Sprich: Wenn der Rest geht, würde ich die beiden Register einfach nicht abfragen.

juggi1962

@badsnoopy667
Die Fehler kommen nur bei 37100 und 37200
Ich habe aber das Skript von @Alex-Warkentin und da wurde einiges rausgestrichen.
bei dem Original Skript kamen viel mehr Fehlermeldungen.
Hier das Skript.

Kommentier die beiden Zeilen wo 37100 und 32000 abgefragt werden doch einfach aus! Also // davorschreiben, so wie das im Script bei anderen Zeilen ja auch schon gemacht wurde.

Meinst du diese?

Brauch ich die gar nicht?

badsnoopy667

@juggi1962
Ja, das sollten die beiden Zeilen sein. Die brauchst Du nur, wenn du die beiden Register abfragen willst. Aber wie gesagt: Da steht meiner Meinung nach nix wirklich wichtiges drin. Wenn es also nicht klappt, würde ich die einfach nicht abfragen und gut ist.

Okay Danke, werde ich mal versuchen.
