[HowTo] Huawei SUN2000 WR Modbus mit node-red (read + write)
-
@murokey Hi!
Hast Du es mal mit meinem Flow von oben probiert? Auf den ersten Blick sehe ich bei Dir zwar keinen Fehler, aber ich weiß nicht, ob man diese "buffer parser" nodes nicht doch braucht. In denen wird ja eingestellt in welcher Form die Daten kommen, z.B. Int16 oder Int32.
Nimm doch mal meinen Flow und davon dann nur einen Teil und trag da Deine UnitID und IP überall ein. Geht es dann auch nicht? -
@badsnoopy667 Leider funktioniert es dann immer noch nicht. Kann es sein das ich noch irgendwie einen Port freischalten muss?
Allerdings sollte hier alles passen.
Kann es an der UnitID liegen? Die muss ja im Modbus-Getter und im Modbus-Client gepflegt werden. Entspricht die UnitID der im RS4851_1 Menu unter Komm.adresse definierten Nummer?
Und eine weitere Frage? Gibt es eine Aussage zur APP? Funktioniert es mit der FusionSolar, mit der SUN2000 oder mit beiden?
Ich konnte bisher nur Einstellungen mit der FusionSolar machen, da ich mit der anderen keine Verbindung hin bekommen habe. -
@murokey
Du hast nicht zufällig parallel noch den Modbus Adapter oder ein anderes Programm das per Modbus auf den WR zugreift laufen, oder? Mein Halbwissen sagt mir, das der Client immer nur eine Verbindung gleichzeitig aufbauen kann.Zur App, ich hab es mit SUN2000 eingestellt (bzw. mein Elektriker). FusionSolar habe ich nicht probiert. Nachdem es bei einigen ja doch Probleme gibt habe ich mir überlegt, ich gehe da auch erstmal nicht mehr dran. Hier funktioniert es ja.
-
@murokey
Ja schau ob noch ob etwas anderes auf den Modbus zugreift.
Ausserdem muss auch die Registernummer stimmen. Die ist bei Huawei nicht immer gleich.
Hier mal meine Einstellungen. Ich habe den SUN2000-8KTL-M0. Der SUN2000-8KTL-M1 hat glaube ich andere Registernummern. Ausserdem hatte ich ich zum testen den Stecker, der zum Smartmeter geht, abgezogen. Keine Ahnung ob das geholfen hat. Aber mit einmal ging es ab da. Nun läuft es auch mit Stecker.
Ich habe keine Ports Freigegeben. NodeRed läuft im Iobroker auf einem Nuc. Nuc hängt im LAN an einer Fritzbox.
Wechselrichter hängt im WLAN.
-
Hallo,
bekomme so halbherzig Daten mit Node-Red raus. Habe mit meinem Spieltrieb parallel dazu den Modbus-Adapter gestartet. Und siehe da, es kommen jetzt auch hier plausible Daten rein. Leider bricht die Verbindung hier nach einem Zyklus wieder abMit Node-Red habe ich das Problem, dass ich vom 2ten WR nur ein paar Daten bekomme. Die aktualsierung der Daten hört mitten drin auf, zwischen den Register 32018 und 32019. Dann kann ich noch ein für mich nichtssagendes Fehlerprotokoll anbieten
-
@biervoegelhasso Wie kann ich herausfinden welche Unit-Id ich für den Wechselrichter (SUN2000-10KTL-M1) einstellen muss? In deinen beiden Bildern ist ja einmal 2 und einmal 3 konfiguriert.
-
@murokey Bei der Unit ID war ich mir auch nie 100% sicher. Mir ist auch nicht aufgefallen das ich in dem Script unterschiedliche IDs vergeben habe. Ich habe das Script nun korrigiert. Meine ID ist die 2. Verändere ich auch nur bei einem Register die ID auf 3 bricht die ganze Verbindung ab. Nur mal als Tipp.
Mit zwei Programmen auf den Bus zuzugreifen ist mist. Das kann nicht funktionieren. -
@captainchaos666
Kann es vielleicht sein, dass Dein Abfrageintervall für die Menge an Registern zu kurz ist? Der ließt die ja alle schön nacheinander ein. Vielleicht wird er einfach nicht fertig. Die wenigsten dieser Daten braucht man ja "live". Ich frage nur eine handvoll Daten im 5 Sekunden Takt ab, den Rest 1x pro Minute.
Und ja, die UnitID muss überall stimmen.
In der Übersicht der Modbus Register von Huawei (Version 3) steht:
"Based on the TCP communications host, unit 0 is used by default to access the
directly connected slave node, and other addresses are used to access the
downstream devices of the slave node. The default address of the slave node is 0.
The address is adjustable."
Kann also auch 0 sein, fängt nicht mit 1 an! -
@badsnoopy667 Ich möchte mich vorab schonmal für die vielen hilfreichen Antworten bedanken. Mittlerweile konnte ich erstmal eine Verbindung herstellen.
Nach Kontakt mit Huawei war das Problem eine veraltete Firmware des Dongles. Nachdem ich den Dongle auf Version SPC127 geupdated habe funktioniert es soweit ich das bis jetzt beurteilen kann.Ich möchte hier meine Erkenntnisse zusammenfassen:
-
Laut Huawei muss der Dongle mindesten Firmwarestand SPC123 haben
-
Für ein Update muss sich mit der FusionSolarApp mit dem Dongle (nicht dem WR) verbunden werden. Das hat bei mir erst funktioniert als ich den Dongle per USB-Ladegerät angesteckt habe, da ich ihn am WR angesteckt nicht im WLAN finden konnte.
Anleitung im Spoiler:
-
Anschließend wie schon oben immer Beschrieben mit der FusionSolarApp auf den WR verbinden und unter Einstellungen -> Kommunikationkonfiguration -> Dongle-Parametereinstellungen Modbus TCP aktivieren und ggf. in den RS485_1 Einstellungen die Komm.adresse anpassen. Diese entspricht später der UnitID in Node-Red.
-

@murokey
Ich dachte mit der Firmenware des Dongles weißt du. Das du dich mit dem Dongle nicht verbinden konntest lag bestimmt an einer zu alten Firmenware. Das Problem hatte ich auch. (The SDongle that needs to be upgraded should have firmware version SDongleV100R001C00SPC115 or later, otherwise the upgrade cannot be performed locally.)
Der Huawei Support hat dann per Fernwartung ein Update gemacht. -
Arbeitet ihr allgemein mit Node-red als separater Installation oder mir dem Node-Red Adapter des ioBroker?
Ich habe Node-red separat installiert und finde irgendwie keine Möglichkeit wie ich die iobroker in und iobroker out nodes herbekomme.
-
@murokey ich habe den Adapter installiert. Wusste nicht mal, dass das auch anders geht.
Bisher nutze ich es auch ausschließlich für den Huawei WR. Und dafür funktioniert es einwandfrei. -
So, ich habe neue Infos, der ktl 30-m3 kann anscheinend kein Modbus TCP mit dem Dongle, es soll angeblich ein Firmware update geben irgendwann mal. Na toll.
habt ihr alle hier kleinere Modelle vom ktl m3?gruß
-
@ple
Ich habe einen 10KLT-M1, dieser wird ja schon mit dem WLAN-FE Dongle ausgeliefert und nach den Startschwierigkeiten bekomme ich jetzt auch die Daten rein. -
@ple
Also ich habe auch einen KTL30-M3 und es funktioniert mit Node Red.
Dongle Version 123
Wechselrichter Version 111
Die nachfolgenden Versionen hatte ich ausprobiert und dann wieder downgegraded. Ging nicht.

Noch vergessen, vorher natürlich die entsprechenden Datenpunkte einrichten.

Hallo,
meine PV mit Huawei WR kommt (hoffentlich) nächste Woche, aber ich habe schon einmal Node Red auf IOBroker aufgesetzt und Deinen Flow (Vielen Dank) importiert. Wie kommt es, dass einige 'IOBroker Out Nodes' im Status 'connected' angezeigt werden, obwohl 0_userdata.0.Huawei nicht existiert?

Also der Flow ist nicht von mir, sondern hier aus dem Forum. Ich möchte mich nicht mit fremden Federn schmücken.@warp-it said in [HowTo] Huawei SUN2000 WR Modbus mit node-red (read + write):

Kann es sein, das die IP-Adresse die in der Wlan-Fe angegeben ist bei dir von einem Gerät belegt ist und er dahin connected?

Nö, die in WLAN-FE eingetragene IP-Adresse existiert in meinem LAN nicht.

Danke für die Top Anleitung, mit dem Modbus Adapter bin ich verzweifelt. Jetzt nach etwas Recherche bin ich auf deine Anleitung über NodeRed gestoßen und siehe da.... es geht auf anhieb.
Da ich vorher noch nie mit NodeRed was zu tun hatte bin ich entsprechend wackelig auf den Beinen damit. Was ich nicht umgesetzt bekomme sind die Alarme bzw. der Status des Wechselrichters.
Dort sind ja als Datentyp "Bitfield16" hinterlegt (z.b. Adresse 32000). So bekomme ich das aktuell in einen State geschrieben: [[{"bits":[0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0],"bit0":0,"bit1":1,"bit2":1,"bit3":0,"bit4":0,"bit5":0,"bit6":0,"bit7":0,"bit8":0,"bit9":0,"bit10":0,"bit11":0,"bit12":0,"bit13":0,"bit14":0,"bit15":0}]]
Jetzt wäre mein Ansatz es mit Blockly/JS zu zerlegen um an die Statis zu kommen. Aber gibt es ggf. mit NodeRed eine fluffigere Möglichkeit die einzelnen Bits direkt auszuwerten und nur wenn der Bitwert 1 ist auch ein State aktualisiert wird?
