In the application, go to your device, then "Settings".
Go in the "Connection" tab to enable Modbus TCP, and set the Modbus TCP server to "Read and Write" mode (HEMS Read and Write). In "Read only" mode the EMS can read the charger's data but cannot control its charging current.
Give the charger a fixed IP address in the same network as the EMS.
