[gelöst] ModbusAttr: Fehler beim Schreiben. function code 0x10 als Ursache?

[FhemPiUser]

Hallo Zusammen,

ich bin dabei meine Lambda-Wärmepumpe per Modbus an fhem anzubinden. Lesen der Holdingregister funktioniert bereits, aber beim Schreiben mit dem u.g. Code für h0102 bekomme ich immer ein Fehler "ungültiger Wert" von der Wärmepumpe.

Laut Lambda Modbusprotokollbeschreibung muss beim Schreiben "function code 0x10 (write multiple holding registers)" verwendet werden. Ist dies bei ModbusAttr mit dem o.g. Code der Fall oder muss ich noch irgendetws einstellen?
