Jahresrückblick 2025 – unser neuer Blogbeitrag ist online! ✨

[Homoran]

@Strike498 ich hab jetzt due 75 Seiten Bedienungsanleitung quergelesen, ich verstehe gar nix!
Da sind viel zu viele Optionen.

ich weiß jetzt erst recht, warum ich diese Dinger meide

[Strike498]

@Homoran

Hmm okay, dann geht’s nicht nur mir so.

Du empfiehlst usb2rs485?

[Homoran]

@Strike498 ich hab die großen waveshare

und die kleinen Sticks

läuft alles ohne Probleme.

Wenn was icht auf Anhieb passt, kann man es schnell eingrenzen

[Strike498]

@Homoran

Hmm okay, dann muss ich nur schauen wie ich ein Kabel von meinem RPi zur Heizung bekomme.

[Homoran]

Dann versuchen wir noch was!
ohne Gewähr

stell den Adapter auf modbus tcp

und den Konverter auf tcp to rtu

[Strike498]

@Homoran
In der Hoffnung, dass du was erkennst, hier sind die Modi, die ich im konverter einstellen kann.

[Homoran]

genau so

und im Adapter auf TCP

[Strike498]

@Homoran

Da bekomme ich dann diese Errors im Log.

[Homoran]

Den Modbus Adapter hast du auf TCP gestellt?
Ist der jetzt auch Master?

[Homoran]

Was sind das für function codes?? 100 und 64?
die kenne ich nicht

Das ist/wird jetzt experimentell!
da musst du mit den Parametern spielen.

Üblicherweise ist der ioBroker der Modbus Master und das Gerät der Client.
stell das mal um.

[Strike498]

@Homoran
Modbus Adapter ist auf TCP und Master gestellt. Fehler bleiben leider bei FC100.

[Homoran]

was bietet der Konverter in dem pulldown 'server' bei eth network sonst noch an?

[Homoran]

@Strike498 sagte in HDG Heizung über Waveshare Modbus Gateway:

2025-12-02 22:30:31.142 - info: modbus.0 (302084) Connected to slave 192.168.178.143

das sieht schon mal gut aus.
Die Eth verbindung Adapter <-> Konverter steht.

aber
Die Abfrage der/des Registers klappt nicht
Das kann natürlich auch an der Konfiguration der seriellen Seite liegen.

Mach mal den Haken bei Aliases verwenden rein.
(hab allerdings keine allzugroße Hoffnung)

[Strike498]

@Homoran sagte in HDG Heizung über Waveshare Modbus Gateway:

Da gibt’s noch „Client“. Das habe ich jetzt ausgewählt, aber dann kann er laut Log nicht mal mehr connecten.

Hat leider auch nichts gebracht.

[Strike498]

@homoran Wenn dir nichts mehr einfällt werde ich wohl doch versuchen auf usb2rs485 zu gehen und irgendwie das Kabel zu ziehen.

[Homoran]

Sorry, mit den RTU2ETH kenne ich mich gar nicht aus.

[Strike498]

@Homoran schade, danke trotzdem

[Ganner86]

Welche Steuerung hast du in der Heizung verbaut? Die Touch und Touch XL haben meines Wissens nach ein RJ45 zum einbinden ins Netzwerk. Darüber lassen sich auch viele Daten lesen. Da gibt es auch einen fertigen Adapter für den IOB.

[Strike498]

@Ganner86 Hey, danke für deine Antwort.

Welcher Adapter ist das denn? Am Netz hab ich die Heizung schon.
