Huawei Sun2000 & ioBroker via JS script funktioniert

road_runner31

@chris_b Hab das Script jetzt auch angepasst. Hier ein Auszug aus dem Log vom iobroker:

Die IP vom Wechselrichter ist korrekt, evcc läuft ja in einem zweiten Container und beschwert sich auch nicht ;)

@badsnoopy667

Kennst du auch Adressen für die Spannung (Unit "V") (und evtl. Temp.) der 5kWh Akkupacks ?

Ich würde gerne die Akkugesundheit prüfen und später überwachen.

In Fusionsolar kann ich zum aktuellen Zeitpunkt die Spannung und Temperatur der beiden Akkus sehen. Historische Daten kann ich mir aber nicht anzeigen lassen.
Das würde ich mir gerne in ioBroker als Graph anzeigen lassen.

In" solar-inverter-modbus-interface-definitions-v3.0" habe ich die Adresse nicht gefunden. Aber Kachel hatte ja auch Adressen in seinem javascript, die dort nicht zu finden waren.

@besimo
Batterietemperatur usw. ist doch da!?
z.B. javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.BatteryTemperature

@alle
Hat jemand einen Tipp, wie ich einen Wert ändern kann?
Speziell würde ich gerne javascript.0.Solarpower.Huawei.Inverter.1.Battery.MaximumChargingPower (Register 47075) ändern um erst ab Mittags ordentlich zu laden (dann geht es bestenfalls nicht von der Einspeisung ab) und auch um eine Hysterese einzubauen.
Lesen klappt ja...

Insgesamt hat das Script bei mir ab und zu mal "Schluckauf" und scheint sich dann nicht mehr zu beruhigen. Erst ein Neustart hilft.
Allerdings hab ich eh noch ein anderes Problem, mein Dongle beendet jeden Abend die Verbindung zum FusionSolar Server und baut sie erst morgens wieder auf. Huawei Hotline weiß auch nicht weiter bisher...

@r4
Bezüglich schreiben kann ich dir meine Vorgehensweise über node-red vorschlagen:
https://forum.iobroker.net/topic/51639/howto-huawei-sun2000-wr-modbus-mit-node-red-read-write
Damit limitiere ich die Akku-Entladung wenn das eAuto angesteckt ist. Aber man kann genauso gut die Ladeleistung des Akkus beliebig einstellen.

@badsnoopy667
jetzt hab ich mich schon auf JS eingeschossen, will also erst mal hier schauen ob das nicht klappt bevor ich alles lösche und mit Node-Red neu anfange...

badsnoopy667

@r4 Verständlich. Allerdings kannst Du auch beides parallel nutzen. Du musst das lesen ja nicht über node-red machen. Das kann ja JS bleiben. Das schreiben machst Du dann mit einem mini-node-red flow. Aber über JS müsste es ja auch irgendwie gehen, ich weiß nur nicht wie.

R4

@badsnoopy667
Hat du das getestet? Das klappt bei dir?
Der Dongle reagiert eh schon irritiert, wenn man zu schnell ausliest. Bei gleichzeitigem Zugriff von zwei Seiten klappt es in der Regel gar nicht mehr (bei mir jedenfalls, wenn ich manuell per "Modbus Poll" das Register beschreibe), dann kommen ständig Timeouts/Fehlermeldungen.

badsnoopy667

@r4
Ja, das ist bei mir auch so. Ich habe mir so geholfen, das ich die Lesen-Abfrage einfach 30 Sekunden pausiere, wenn ich schreiben will. Dann geht es "fast" immer.

Chris_B

@besimo Kurzer Hinweis: Es gibt sowohl die Temperatur des Stack:
javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.BatteryTemperature

Es gibt aber auch die Temperaturen (min und max) der einzelnen Packs:
javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.Battery1.MaxTemperature

(obwohl ich letzteres nicht ganz einsehe; wieso gibt es min/max? Im Manual von Huawei finde ich auch keine bessere Beschreibung).

Moin!

Vielen Dank für das script...aber irgendwie bin ich gerade überfordert...
Habe die ID vom WR rausgefunden (1)...eingetragen...aber irgendwie kommen Fehlermeldungen...ich vermute es kommt vom PowerMeter...aber irgendwie komme ich nicht auf ne Lösung

Jemand ne Idee für mich?

Oder hab ich doch die falsche ID vom WR?

Dank @chris_b

habe ich nunmehr alle Daten meines Wechselrichters und der beiden Batterien im Iobroker drin.

Möchte gerne nun diese gerne Grafisch in vis darstellen. Hatte vorher (für meine kleine Balkonanlage) den Energiefluss adapter benutzt.

Nunmehr habe dank dem Script so viele Datenpunkte, das ich den Wald voller Bäume nicht mehr sehe:dizzy_face: . Hat jemand vielleicht eine Vorlage für Vis. So das ich die ganzen Werte vielleicht besser zuordnen kann.

Gruß Sven

Vielen dank noch mal für das tolle Script.

Chris_B

@svenomatt
Hallo Sven. Ich bin nicht sicher, wie man Vis Skript gut teilen kann. Aber hier einmal eine Erklärung.
Ich habe folgendes in der Vis:

Von links nach rechts stelle ich folgendes dar (das meiste entspricht direkt der Huawei Mobile App):

Yield Today: javascript.0.Solarpower.Derived.YieldToday
Bat Charge: javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.CurrentDayChargeCapacity
Bat Discharge: javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.CurrentDayDischargeCapacity
Batterie Prozent: javascript.0.Solarpower.Huawei.Inverter.1.Battery.SOC, darunter javascript.0.Solarpower.Derived.BatteryOverview
Beim Solarpanel, aktuelle Leistung: javascript.0.Solarpower.Huawei.Inverter.1.InputPower
Beim Solarpanel, Spannung, Strom: javascript.0.Solarpower.Huawei.Inverter.1.String.1_Voltage, javascript.0.Solarpower.Huawei.Inverter.1.String.1_Current
Leistung zur/von Batterie: javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.ChargeAndDischargePower
Pfeilrichtung Batterie: javascript.0.Solarpower.Derived.IsBatteryLoading (damit kann der Pfeil nach links oder rects zeigen)
Leistung zu/von Netz: javascript.0.Solarpower.Huawei.Meter.ActivePower
Pfeilrichtung Netz: javascript.0.Solarpower.Derived.IsGridExporting
Leistung Haus: javascript.0.Solarpower.Derived.HouseConsumption
Tagesverbrauch Haus: javascript.0.Solarpower.Derived.ConsumptionToday
Export Today: javascript.0.Solarpower.Derived.GridExportToday
Import Today: javascript.0.Solarpower.Derived.GridImportToday

Das Batteriesymbol ist ein png mit dahinter gelegtem Bargraph, entspricht also dem Füllstand.

Ich hoffe, das hilft Dir...
Ich habe das Skript noch etwas erweitert und poste das noch separat.
Gruss, Christian

Chris_B

Ich habe das Skript nochmals etwas erweitert:
Jetzt werden auch jeden Tag 1 Minute vor Mitternacht die Tagesdaten in die Datei /opt/iobroker/iobroker-data/SolarpowerLog.csv geschrieben. Pro Tag werden folgende Daten geschrieben:

Datum
Yield Today
GridExportToday
GridImportToday
ConsumptionToday

Mit dieser csv Datei kann man dann in Excel wunderbar seine eigenen Stattistiken zeichen und analysieren.
Gruss, Christian

ACHTUNG: Irgendwie kopiert es mir das Skript komisch in den 'Code' Bereich. Bitte die komischen {1} im Skript wegnehmen. Weiss jemand, wie diese entstehen? Die sind im Code nicht drin, und ich habe mehrere Arten versucht es zu kopieren...

@mrlee Kommen denn dauernd solche Meldungen oder nur manchmal?
Die IP Adresse des WR müsstest du schon wissen :face_with_rolling_eyes:
Beim POwermeter habe ich einfach einmal, wie oben beschrieben die Standard-Adresse genommen...

@alle
Hat jemand einen Tipp, wie ich einen Wert ändern kann?

Also der Schreibbefehl (via Write Multible Registers / FC16) für 750W als maximale Ladeleistung wäre:

    // write the value 0, 750 to registers starting at address 47075
    client.writeRegisters(47075, [0, 750]);

(Es sind ja 2 Register zu beschreiben.)
Das Ding ist, dass die Schreibfunktion natürlich auch mit der Huawei-typischen Verzögerung, also zeitlichem Abstand zu anderen Register-(Lese-)Funktionen kommen muss. Da gibt es verschiedene Möglichkeiten, das in die "setInterval"-Hauptfunktion reinzubekommen, unter der Beachtung, dass man ja auch nur einmal schreiben muss bei einer Änderung, danach aber wieder regelmäßig die Register ausliest...

Vielen Dank für´s teilen deines Skriptes.

Ich wollte dein neues Skript ausprobieren, bekomme aber eine Fehlermeldung:

04:50:20.523	error	javascript.0 (430) script.js.Solar.Chris_B_neu compile failed:
 at script.js.Solar.Chris_B_neu:427

Kannst du mir sagen, wo der Fehler liegt?

Hallo Sven. Ich bin nicht sicher, wie man Vis Skript gut teilen kann. Aber hier einmal eine Erklärung.
Ich habe folgendes in der Vis:

Von links nach rechts stelle ich folgendes dar (das meiste entspricht direkt der Huawei Mobile App):

Yield Today: javascript.0.Solarpower.Derived.YieldToday
Bat Charge: javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.CurrentDayChargeCapacity
Bat Discharge: javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.CurrentDayDischargeCapacity
Batterie Prozent: javascript.0.Solarpower.Huawei.Inverter.1.Battery.SOC, darunter javascript.0.Solarpower.Derived.BatteryOverview
Beim Solarpanel, aktuelle Leistung: javascript.0.Solarpower.Huawei.Inverter.1.InputPower
Beim Solarpanel, Spannung, Strom: javascript.0.Solarpower.Huawei.Inverter.1.String.1_Voltage, javascript.0.Solarpower.Huawei.Inverter.1.String.1_Current
Leistung zur/von Batterie: javascript.0.Solarpower.Huawei.Inverter.1.Batterystack.1.ChargeAndDischargePower
Pfeilrichtung Batterie: javascript.0.Solarpower.Derived.IsBatteryLoading (damit kann der Pfeil nach links oder rects zeigen)
Leistung zu/von Netz: javascript.0.Solarpower.Huawei.Meter.ActivePower
Pfeilrichtung Netz: javascript.0.Solarpower.Derived.IsGridExporting
Leistung Haus: javascript.0.Solarpower.Derived.HouseConsumption
Tagesverbrauch Haus: javascript.0.Solarpower.Derived.ConsumptionToday
Export Today: javascript.0.Solarpower.Derived.GridExportToday
Import Today: javascript.0.Solarpower.Derived.GridImportToday

Das Batteriesymbol ist ein png mit dahinter gelegtem Bargraph, entspricht also dem Füllstand.

Ich hoffe, das hilft Dir...
Ich habe das Skript noch etwas erweitert und poste das noch separat.
Gruss, Christian

Genau so etwas habe ich gesucht.
Vielen Dank

@xanon Sorry, es scheint evtl. ein Copy/Paste Fehler im Skript zu sein. Ich habe das Skript oben temporär entfernt. Prüfe das, und stelle das Skript dann wieder ins Forum.
Gruss

Xanon

@chris_b

Ahh ok, danke für die Rückmeldung
