Heidelberg control per Modbus RTU anbinden

[thomasg]

Hallo zusammen,

wir haben eine Heidelberg Control die ich gerne per Modbus an fhem/raspi anbinden möchte.

Könnt ihr mir da einen guten/Preiswerten USB rs485 Adapter empfehlen, der gut mit fhem zusammenarbeitet?

Welches fhem Modul müsste ich nutzen um mit der wallbox zu kommunizieren?

Danke

Soweit ich weiß gibt es da ein Modul wbec, meine WB hat aber schon WLAN, so dass Modbus via TCP funktioniert. Ansonsten habe ich bei mir einige CDSENET NA111-A Umsetzer mit FHEM am Laufen, da ich Ethernet lieber mag als USB.

Die kompletten Register sind bei Amperfield auf der Homepage zu finden, für mich haben diese aber ausgereicht und man kann sich anhand der Vorlage auch schnell andere Register hinzufügen.
Damit ich mitbekomme, wenn was nicht in Ordnung ist habe ich noch folgende DOIF's definiert:
