Kermi und Modbus

[Fistandantilus]

Hallo zusammen,

ich habe eine Kermi x-change 16 awe Wärmepumpe und möchte diese per ModBus TCP einbinden. Der Support hat mir den ModBus bereits freigeschaltet, was erst mal Grundvoraussetzung war.
Die Verbindung selbst steht, aber ich komme mit dem Auslesen der Register nicht weiter. Die vorliegenden Infos sind im Anhang.

Ich habe jetzt versucht z.B. die Außentemperatur auszulesen:

Code Auswählen Erweitern

attr Kermi obj-h1504-reading Außentemperatur
Das scheint aber nicht zu passen, im Log sehe ich dann folgende Infos:

Ansonsten habe ich noch aus einer anderen Konfig folgendes drin stehen:

Code Auswählen Erweitern

dev-h-defLen 2
dev-h-defPoll 1
dev-h-defUnpack N

Wäre für Eure Hilfe sehr dankbar

Ich habe auch nochmal Register 1504 umgewandelt in Dezimal, vielleicht is es ja in Hex angegeben, aber kein Erfolg. Folgendes Log mit beiden Varianten:

Ich habe gerade mal mit QModMaster geschaut. Damit bekomme ich Werte geliefert. 177 entspricht aktuell 17,7 Grad Außentemperatur. Passt also.

[Fistandantilus]

Ich glaube ich habe es gelöst. ID musste 1 sein. Mit Len 1 und unpack n kommen jetzt erstmal Werte, die ich noch formatieren muss, sieht denke ich aber ok aus.
