Huawei Sun2000 & ioBroker via JS script funktioniert

[striegel26]

@alex-warkentin ja mir kam das auch komisch vor mit der ID11 aber schau ...... oder verstehe ich da was falsch? WR mit 16 und 1 mein fehler 16 ist gelöscht natürlich.

[Alex Warkentin]

@striegel26 Ich bin mir da nicht sicher. Bei mir steht dort auch die 11 drin, aber ich habe die 0 von Anfang an stehen gelassen und damit funktioniert es.

[striegel26]

@alex-warkentin Oh man ja die 0 ist es !!! Danke dir Jetzt funktioniert alles

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
ATARI

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

[ATARI]

@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.

[Alex Warkentin]

@juggi1962
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?

[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.

[juggi1962]

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

[juggi1962]

@alex-warkentin
Super Danke, werde ich gleich probieren

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

[Alex Warkentin]

@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

Super Danke.
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
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
