3. Connect the GARO charger to the same Wi-Fi network as the Reduxi controller

For communication between the Reduxi controller and the GARO charger, both devices must be connected to the same network. As outlined in point 2.1, the same network must also be selected for Reduxi, whether it's LAN or WLAN.

Once this criteria is met proceed to OCPP settings.

 

4. Configuration for OCPP communication between the GARO Charger and the Reduxi controller

4.1  Add device

First login to the local Reduxi configurator and add a new device by clicking on the 'Add device' button.

 

4.2 Select the device that would you like to add

Within the first step select basic settings:

• Select Device type: EV charger,
• Select Type: OCPP 1.6 - JSON,
• And define the name.

4.3 Device Configuration for OCPP

The second step is used for the Communication channel, for OCPP communication to work properly. First, fill in the Device identifier obtained from the GARO Charger.

When OCPP JSON 1.6 protocol is utilized, server OCPP URL is needed, generated by Reduxi controller. URL can be obtained 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 Reduxi, the final step is to paste it into the GARO charger to establish the OCPP connection. Navigate to the GARO Charger’s 'Configuration' section, then 'OCPP Settings,' scroll down to 'GaroCsmsURL,' and paste the URL.

 

       

 

 

4.5 Test communication

To ensure that OCPP communication is established, a communication test can be performed via the 'Test communication button' located bottom right after all Communication channel fields.

There are three different cases of communication response.

Case 1: Communication is working properly.

Case 2: Unable to communicate with device 1, the ID of the device is not set or is different.

Case 3: No device with OCPP 1.6 communication is found.

4.6 Default parameters

Fill in the advanced settings and choose the parameters shown in the image below. Settings can vary depending on location needs. Once you are done, click on the 'Done' button down right on your screen.

4.7 Readings from Device

The purpose of this point is to show how to check readings from the device. This is done under 'Device/Last measurement'.

Once the device is successfully added through the configurator, it can be monitored via the cloud application Reduxi. 

4.8 Factory reset

In cases where the charger is relocated or needs to connect to a different network, a factory reset may be required. To perform a factory reset, press and hold the test button for 20 seconds, then reconfigure the GARO charger.
