Integrate Reduxi with the ETREL INCH Core/Pro charger via Wi-Fi, utilizing the OCPP protocol. Reduxi's flexibility allows cost reductions of up to 30%.

1. Etrel INCH Core app:

1.1 Etrel INCH Core tehnical documentation:

1.2 The application is available on the Google Store:

https://play.google.com/store/apps/details?id=com.landisgyr.inchcore&hl=en_US

1.3 The application is available on the Apple App Store:

https://apps.apple.com/us/app/inch-core/id6475773662

2. Connect to ETREL INCH core to Wi-Fi

Detailed instructions are demonstrated on the link:

3. Connect to ETREL INCH PRO charger

Once the charger is connected to Wi-Fi, it can be accessed directly. The connection is established by opening the charger's IP 192.168.1.250 address in the user's preferred browser.

user: root@etrel.com

password: toor

3.1 Connectivity to OCPP backend server (Reduxi)

Once connected to the EV charger, go to the "Connectivity" section (first picture) and paste the Reduxi server URL (point 4.3) into the backend server field, as shown in the second picture below.

NOTE: Copy Charger point identity so it can be used in point 4.3.

4. Connect to ETREL INCH CORE Charger

The charger must be connected to an access point using a special username and password. To establish the access point, the front cover of the charger needs to be disassembled — the access point is then created automatically by the charger.

Steps for OCPP Configuration

Open the app (1.2 The application is available on the Google Play Store) and connect to the charger's access point.
Click on Manage Access Password.
Add a new password (Admin access)

Important: The Admin username and password are hidden parameters and can be obtained during installation for a specific location. If needed, please contact support@reduxi.zendesk.com and the support team will provide them.

Configure the OCPP settings by following the instructions in 3.1 Connectivity to OCPP backend server (Reduxi)

4. OCPP communication between the ETREL INCH core and the Reduxi controller

4.1 Add device

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

4.2 Select the device that you would like to add

Within the first step select basic settings:

Select Device type: EV charger,
Select Type: OCPP 1.6 - JSON,
Name the device.

4.3 Device Configuration for OCPP (Communication channel)

The second step is used for the Communication channel, for OCPP communication to work properly. First, fill in the Device identifier (Charger point identity) obtained from the EV charger SW interface, which needs to be set in the communication channel.

When the OCPP JSON 1.6 protocol is utilized, the OCPP server URL is needed and generated by the Reduxi controller. URL can be obtained directly from the Communication channel.

Example URL: ws://192.168.1.200/ocpp/1.6/json/

4.4 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, displayed in the upper image from previous point.

There are three different cases of communication response.

Case 1: Communication is working properly.
