Huawei Sun2000 & ioBroker via JS script funktioniert

@majawe
Hier der Flow für beide Zustände (Charge und Discharge)
flows_read_write_charge_discharge.json
Sobald du eines der beiden Objekte "_SET" änderst (vorher anlegen!), wird das entsprechende Register geschrieben.
Und wie immer bei meinem Flow: Achte auf die Unit-ID. Bei mir ist die 2, bei dir vermutlich nicht! Mein WR war mal defekt.

Hast Du darauf geachtet beim Ändern nicht nur den Namen, sondern wirklich die Adresse zu ändern? Das hab ich schon ein paar mal durcheinander gebracht. Der Name allein hilft nicht, der ist sowieso völlig beliebig.

@badsnoopy667 Funktioniert heute auf Anhieb komischer weise ich denke es lag am Dongle update

Tou kannst du auch online umstellen unter, https://region02eu5.fusionsolar.huawei.com, Dongle, EMS Control oder direkt am Handy unter Dongel, Parametereinstellung, Arbeitsmodus Tou.

Also brauchst dich nicht direkt am Wechselrichter einloggen

@badsnoopy667 Super so wird es gemacht
Danke

@majawe
Schön, dass es klappt! Aber ENT-laden im Ladezeitraum tut er nicht, oder? Das ist nämlich vermutlich noch der Haken. Den Zeitraum würde ich ja immer (in der Nacht) stehen lassen und über die Ladeleistung dann quasi aktivieren und deaktivieren.
Wobei man streiten kann, ob das ein Problem ist, im Winter ist der Akku Nachts sowieso fast immer leer. Dann spielt es keine Rolle. Und im Sommer brauche ich ihn ihn nicht extern laden.

Zu der FusionSolar Seite: Wo geht das denn? Bei mir kann ich da gar nix einstellen. Welche Dongle Firmware ist das? Oder hast Du da Installateur Zugriff auf FusionSolar?

majawe

@badsnoopy667 Ich denke bei sonnenuntergang setze ich den auf 0watt, und dann wenn kleiner als 5cent = 5000Watt. Den Rest erledigt Tou zwischen 0 - 5 Uhr.

majawe

@badsnoopy667 Ich habe den Installateur zugang, da ist der Punkt sichtbar. Der Dongle hat die FW PC133 am ende aber gesehen habe ich den Punkt bereits mit der PC130

Erst mal vielen Dank für das Script, hat fast sofort funtioniert.
Ich musste nur die IDs raten, bei meiner nagelneuen Anlage mit 2 KTLs und dem Powermeter und ohne Batterien bin ich hier gelandet:

const ModBusIDs = [1, 2];
const PowerMeterID = 0;

Powermeter läuft wunderbar.
Das Problem, daß die Werte nur einmal geschrieben wurden habe ich mit einem Workaround hier gelöst:

function forcesetState(objectname, value, options) {
    if(!existsState(objectname)) {
        createState(objectname, value, options);   
        console.log("createstate " +  objectname + " to value " + value);     
    }
    //Workaround 
    setState(objectname, value);
}

also das setstate aus der else-clause genommen, denn das !existsState scheint nicht sauber zu funktionieren.

Ach so, noch eine gute Nachricht:
Der Installateur kann den Modbus (inwischen?) remote aktivieren, da muss keiner vor Ort sein.
Hat mich eine Mail an meinen Solateur gekostet und zwei Stunden später war alles aktiv.

@zoid1988 Hallo zusammen, gibt es hier Neuigkeiten. Hab heute mein WR angeschlossen. Datenpunkte wurden generiert aber erhalte den selben Fehler. Gibt es Lösungen? Danke an alle für die Hilfe!

Ich habe auch den Workaround eingesetzt, erhalte immer aber die gleiche Warnung:

Dear all, any support on my issue (see above).

Thanks for your support

Thomas42

@oswibz
Als Newbie: Da stimmen Deine IDs nicht. So, wie ich das Script verstehe, gibt es die ID, aber es ist nicht der Gerätetyp, der abgefragt wird.

oswibz

@thomas42
wo finde ich den korrekten ID?

Thomas42

@oswibz Keine Ahnung, ich habe geraten.
Das Smartmeter scheint immer die Null zu sein, der erste WR war bei die 1, der zweite die 2.

@wilher Hi,
wäre eventuell hifreich, wenn Du Dein Log posten würdest und nicht das Script

zoid1988

@oswibz

Leider gibt es hier bei mir nichts neues ... Es funktioniert immer noch nicht ...

Alex Warkentin

Ich habe das Script gerade erfolgreich eingerichtet. War nicht ganz so einfach. Daher hier noch ein paar Tipps:

Javascript Adapter und Nodejs sollten auf dem neuesten Stand sein, oder zumindest zueinander passen.

In den Einstellungen des Javascript-Adapters muss die Erweiterung "modbus-serial" eingetragen werden (einfach reinschreiben und bestätigen). Bei mir meckert das Script danach trotzdem über die Zeile, funktioniert aber.

Die IP eures Dongles muss eingetragen werden (ohne $$$)

// Enter your inverter modbus IP and port here:
client.connectTCP("192.xxx.xxx.xxx", { port: 502 });

Die IDs des WRs und der Batterien könnt ihr im Gerätemanagement in der Fusionsolar Web-Oberfläche herausfinden, oder direkt am Gerät. Dafür braucht ihr aber den Installateur-Zugang. Normalerweise hat der WR aber die ID 1 und der SmartMeter die 0. Bei der Batterie kann ich nicht weiterhelfen. Habe keine.

// Enter the Modbus-IDs of your Sun2000 inverters here:
const modBusIDs = [1];
// On which Modbus-ID can we reach the power meter? (via Sun2000!)
const powerMeterID = 0;

Die existState Funktion ist fehlerhaft, da objectname nicht den vollen Pfad beinhaltet. So funktioniert es:

if(!existsState("javascript.0." + objectname))

Bei der Start- und Stopzeit habe ich die Sekunden in Datum umgewandelt. Bitte auf Groß-Kleinschreibung achten

ForceSetState("Solarpower.Huawei.Inverter." + id + ".StartupTime",              new Date(GetU32(globalDataBuffer[id-1], 32091)*1000),          {name: "", unit: ""});
ForceSetState("Solarpower.Huawei.Inverter." + id + ".ShutdownTime",             new Date(GetU32(globalDataBuffer[id-1], 32093)*1000),          {name: "", unit: ""});

@striegel26 Bist du sicher, dass dein Powermeter die ID 11 hat und hast du zwei Wechselrichter mit 16 und 1?

Was sagen denn deine Protokolle?

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.

@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.
