Using HA Modbus for Logarex LK13BE Smart Meter

Configuration
1

Hi,

i have an Logarex LK13BEXXXX Smart Meter OBIS.
It has an RS485 Output to read out the data from the meter.

Does anyone have an idea how i can read that out with Modbus directly to HomeAssistant?
That was my first try:

modbus:
  name: Stromzaehler
  type: serial
  baudrate: 9600
  bytesize: 8
  method: ascii
  parity: N
  port: /dev/ttyACM0
  stopbits: 1
  sensors:
    - name: slave0
      slave: 0
      address: 0
    - name: slave1
      slave: 1
      address: 1
    - name: slave2
      slave: 2
      address: 2
    - name: slave3
      slave: 3
      address: 3
    - name: slave4
      slave: 4
      address: 4

But i didnt get any data to the sensors…
Any ideas? Its an OBIS Meter

There are some Requests for D0 Smartmeters, but still no solution:

Seems best way is to put an ESP in between:
