Neuer ioBroker-Blog online: Monatsrückblick März/April 2026

[Int17]

@Homoran
Ok, ich hatte die Model number als ID verstanden, da im Kommentar steht Model number of the inverter (8 chars, space padded). Daher im 2. Versuch die Model Number als String definiert.

"Ansonsten mal ein downgrade des Adapters. die 8.0.3 dürfte nicht stable sein. wo hast du due her?"
Ich folge dem Beta-Repo.

Habe jetzt die aus dem Stable Repo installiert.
Versuch mit Waveshare (.80):

Also ich bin ein Stück weitergekommen.
Invalid holdingRegisters address: -10001
Hier ist mir aufgefallen, dass sich die Adresse ändert, wenn man das Holding Register verändert. Trägt man da 40001 ein, so kommt der Fehler nicht mehr und auch die ID-Fehlermeldung kommt nicht mehr.

Super! Ich weiß, Modbus ist mit viel Probieren verbunden. Aber wenn man einen Schritt weiter ist, macht's Freude :-)

[Homoran]

@Int17 sagte in FoxEss H3 Wechselrichter per Modbus in ioBroker:

Invalid holdingRegisters address: -10001

das klingt nach falschen Grundeinstellungen!

Alias verwenden aktiviert?

[Int17]

@Homoran
Ja, die Selektion ist Standard. Jetzt deaktiviert.
Die ersten beiden Register laut Doku sind Model und SN:

die habe ich jetzt eingetragen:

Ergebnis:

Hier die Ausgabe vom GModbus:

Also scheint die FW des H3 Modbus über TCP (LAN-Kabel) zu unterstützen und das RS4852ETH ist überflüssig.

Hatte hier gelesen, dass nach dem Eintrag von ein paar Register, die restlichen automatische gelesen wurden. Stimmt das?

im Modbus Adapter? nein!
in deinem Tool? möglich, aber kenn ich nicht

[Int17]

Falls du GModbus meinst, da auch nicht. Da muss man die Anzahl mitgeben.
Danke für eure Hilfe.

[Int17]

Ich melde mich nochmal, weil ich hier gelesen habe, dass das Auslesen per TCP nicht empfohlen wird. Daher habe ich mir Waveshare RS485 TO ETH Converter

installiert. Hier bekam ich aber keine Verbindung zu H3 Smart. Der Wechselrichter geht in einen Fehlerstatus, wenn man in den Einstellungen "Meter 1" oder "2" aktiviert und trennt die PV-Seite sofort.

Dann habe ich den beim WR mitgelieferten Chint-DTSU666 mit einer Phase und dem Modbus-Kabel (ID 147) verbunden.

Am WR habe ich den COM-Port genommen.

Die ID 247 im WR unverändert gelassen.

Alles zusammengebaut und "Meter 1" wieder aktiviert. Aber auch hier zeigt der WR sofort den obigen Fehler an.
Um zu sehen, ob er überhaupt ansprechbar ist, habe ich mir das Interface USB2Modbus von Waveshare gekauft. Aber auch damit habe ich keine Daten auslesen können bzw. auch damit zeigt der WR den Fehler.

@Int17 sagte in FoxEss H3 Wechselrichter per Modbus in ioBroker:

Waveshare RS485 TO ETH

Hi,

wenn du den Waveshare RS485 TO ETH nimmst, was hast du da genau eingestellt - ist es das?

Und wie schauen die Einstellungen im IOBroker Modbus-Adapter genau aus? Bitte Screenshots.

[EDIT] Bevor beim Waveshare RS485 TO ETH die grüne LED nicht leuchtet, steckt der Fehler höchstwahrscheinlich zwischen IOB-Adapter und Waveshare.

[Int17]

@fuzzy1955
Ja, so sieht die akt. Konfig aus.
"Destination IP" ist die des iobrokers.

In "Einstellungen" nichts geändert.

Nur das eingetragen:

Wenn ich mit GModbus das Waveshare anspreche, leuchtet der Link:

Nur es kommt nicht das erwartet zurück:

Offenbar passt das Offset nicht. Was ist da bei dir eingetragen? Meines schaut so aus:

[Int17]

@fuzzy1955
Das das Offset nicht passt, scheint mir unwahrscheinlich, da es
a) so in der FoxESS Doku drin steht

b) wie gezeigt per LAN auch funktioniert.
Denke nicht, dass sich die Holding Register Adressen ändern, nur weil man statt LAN oder RS485 abfragt.
Du nutzt auch TCP?

1.12
Version: Master (H3_10_Smart)
1.39
Version: Slave (H3_10_Smart)
1.00
