Modbus RTU SDM72

Hello,

I would connect the SDM72 over RTU:

Register: 30053

Length Bytes: 4
Data Format: Float
Units: W
Hi Byte: 00
Lo Byte 034

• name: “Stromzähler Heizung”
  type: serial
  baudrate: 9600
  bytesize: 8
  method: rtu
  parity: E
  port: /dev/ttyUSB0
  stopbits: 1
  sensors:
  • name: “Sensor1”
    unit_of_measurement: W
    address: 30053
    count: 2

The meter is recognized and values are also displayed. Unfortunately only always 0 and not the values from the counter. Can someone help me? I’m just new to Modbus and still have a lot to learn.

Thanks
