You can set bus_datatype to int32 and remove value_multiplier field. This way you can get the raw value that is being read.

I try but again the value is not true. I made other test with script. I create a script that read value from slave and map this value to Modbus register (LM work as Modbus tcp gateway) , then read the value with Modbus poll. Now the read value is ok (-974). But I need to map the register not to Modbus but to knx.
