Modbus profie Satec PM130 Plus

Try this, since the resulting value has to be multiplied by 0.001, bus_datatype field has to be set to float32, but datatype field (which tells what kind of data is read from ModBus) should be set to int32.

Code:

{
   "manufacturer": "satec",
   "description": "PM",
   "mapping": [
      {
         "name": "PF_L1",
         "bus_datatype": "float32",
         "datatype": "int32",
         "type": "register",
         "value_multiplier": 0.001,
         "address": 13342
      }
   ]
}

Thanks for fast reply. I think now the received value is not real ( screenshot in attachment). Value for power factor must be from -1000 to 1000 when is not multiplied.
