1. Install the utility using the command:
    apt update && apt install wb-modbus-ext-scanner
    
  2. Stop the wb-mqtt-serial driver using the command:
    systemctl stop wb-mqtt-serial
    
  3. Execute the command:
    wb-modbus-scanner -d /dev/ttyRS485-1 -b 115200 -s 4267937719 -i 3
    
  4. Where, /dev/ttyRS485-1 is the port to which the device is connected,
  5. 115200 is the exchange rate,
  6. 4267937719 is the device's serial number,
  7. 3 is the new slave ID.
  8. As a result, the following output should appear:
    Serial port: /dev/ttyRS485-1
    Use baud 115200
    Change ID for device with serial   4267937719 [FE638FB7] New ID: 3
    
  9. Start the wb-mqtt-serial driver again using the command:
    systemctl start wb-mqtt-serial
