    Hallo an alle Wissenden :-)
    Funktioniert dieses Skript auch ohne Speicher?
    Ich hab leider keinen Speicher was muss ich dann daran ändern.
    Für mich ist JS Neuland.
    Wäre schön wenn mir jemand helfen könnte.
    Danke im Voraus Gruß Jürgen.

    @juggi1962

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

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

    Gruß

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

      Die Modbus-Ansteuerung vom Huawei Sun2000 Wechselrichter ist über TCP etwas speziell, da nach öffnen des TCP-Ports noch eine Pause eingehalten werden muss, da sonst keine Daten zurück geliefert werden. Auch wird nicht jede Modbus-TCP-Anfrage mit den angeforderten Registern beantwortet. Daher funktioniert die Kommunikation über den normalen Modbus-Adapter im ioBroker nicht.

      Um die verfügbaren Register in den ioBroker zu bekommen hab ich ein js-script geschrieben, dass die Abfrage der Register über TCP macht und die Daten entsprechend parsed. Man braucht dafür im IOBroker nur die ScriptEngine und muss in deren Settings noch die modbus-serial hinzufügen. Danach legt das Script einen großen Satz an Objekten an und aktualisiert die regelmäßig (ca. 2x die Minute). Es werden nur Register gelesen - das Schreiben von Registern ist nicht eingebaut (und bei mir gerade auch nicht nötig). Damit die Netzwerkpakete möglichst groß sind werden die Registern in Blöcken abgefragt.

      Wer möchte kann das Script gerne nutzen. . Einfach IP, Batteriekonfiguration und die Modbus-IDs eintragen und ausführen. Wer es ändern möchte darf dies auch gerne tun - es freut aber sicher alle ioBroker-Nutzer wenn ihr Änderungen auch wieder veröffentlicht.

      Falls jemand noch eine Idee hat, wie man den Huawei File-transfer über Modbus implementieren kann (mit deren speziellem function-code 0x41), würde ich mich freuen. Der fehlt leider damit die Optimierer ihre Echtzeit-Daten in den IOBroker liefern können...

      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.

      Gruß

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

        Hallo an alle Wissenden :-)
        Funktioniert dieses Skript auch ohne Speicher?
        Ich hab leider keinen Speicher was muss ich dann daran ändern.
        Für mich ist JS Neuland.
        Wäre schön wenn mir jemand helfen könnte.
        Danke im Voraus Gruß Jürgen.

        Der Fehler besagt, dass deine ID für den Wechselrichter "undefined" ist. Welche ID hast du im Script eingestellt und hast du sie mit deinen aktuellen Einstellungen abgeglichen?

          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.

          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.

            Gibt es eigentlich eine Möglichkeit die Infos auszuschalten denn so sehe ich im Log ja nur mehr diese von dem Skript.

              ändere mal die Einstellung für den Speicher.

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

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

                            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?

                                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"});

                                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.

                                  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"});

                                  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.

                                      isOpen soll laut Doku eigentlich ein Funktion an. Wird aber als solche nicht zur Verfügung gestellt und ist sonst auch immer true.

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

            triggerprocessing = 1;                    
        }
    }     
}, 3000);

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

                                        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?
