To allow the SmartgridOneController to control the station, you must enable Modbus TCP via the eSetup for Electrician app or the charger's web interface.
Log in to the charger using the eSetup app.
Go to the Network settings and assign a Static IP address to the charger. This ensures the Controller can always find it.
Go to Communication (or Backend) settings.
Set Modbus TCP to Enable.
Ensure the Port is set to 502.
Save the settings and reboot the charger if prompted.

Make sure the Modbus Slave ID is set to 1 (or between 1 and 247). The default address is usually 1 or 255.
