@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 :-)

@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.
