Add to Reduxi (Points 5–7): Log in to the Reduxi web interface. Add the charger via OCPP 1.6 JSON or Modbus TCP/IP. Run Test communication, then click Done.
Go live (Point 8): Check the last measurements. Set the control type to AUTO. Define a strategy.
→ Common issues
| Issue | Solution |
|---|---|
| OCPP test: unable to communicate, device ID not set or different | Enter the device identifier from the right side of the charger (starts with TACW11-4-) in the communication channel (see Point 6). |
| OCPP test: no device with OCPP 1.6 found | Check that the External Server is enabled in TerraConfig and that the OCPP server URL of the Reduxi Controller is entered (see Point 4). |
| Modbus TCP/IP test: IP address not correct | Check the IP address of the charger in TerraConfig and in the communication channel (see Point 7). |
| Modbus TCP/IP test: port not correct | Check the Modbus TCP port set in TerraConfig and enter the same port in the communication channel. |
| Open configurator does not open or stays empty | The tunnel is not active yet. Wait about 30 seconds and check that the controller is online. |
