3. Connect the GARO Charger to the Same Wi-Fi Network as the Redux Controller

For communication between the Redux controller and the GARO charger, both devices must be connected to the same network (LAN or WLAN). As described in step 2.1, the Redux must use the same network as the GARO charger.

Once this criterion is met, proceed with OCPP configuration.

Once this criterion is met, proceed with OCPP configuration.

 

4. OCPP Communication Setup Between the GARO Charger and the Redux Controller

4.1 Add a Device

Log in to the local Redux configurator and add a new device by clicking 'Add Device'.

 

4.2 Select the Device to Add

  • In the first step, configure the basic settings:

    • Device type: EV Charger

    • Protocol: *OCPP 1.6 - JSON*

    • Assign a name.

4.3 Configure OCPP Device Settings

The second step is for the communication channel and OCPP communication testing. Enter the device identifier obtained from the GARO charger.

If using OCPP JSON 1.6, the OCPP server URL generated by the Redux controller is required. The URL can be retrieved directly from the communication channel.

Example URL: ws://192.168.1.121/ocpp/1.6/json/

4.4 Configure OCPP Settings in the GARO Charger

After obtaining the JSON URL from the Redux controller, paste it into the GARO charger to enable the OCPP connection.

Navigate to the 'Configuration' section of the GARO charger, then 'OCPP Settings'.

Scroll down to 'GaroCsmsURL' and paste the URL.
