How to connect GL Charge Publicbox and Platinum EV chargers with Reduxi controller
Connect the GL Charge Publicbox or Platinum to the Reduxi Controller via OCPP 1.6 JSON. Reduxi can execute the DLMS to protect the installation.
1 Required equipment
You need these components:
- Reduxi Controller
- GL Charge Publicbox or Platinum charger
- Laptop or tablet with internet access to configure the device in Reduxi
2 Configure the charger
2.1 Connect the PC to the charger
Connect the PC and the charger to the same network. Then you can open the web interface of the charger.
Set the network on the PC:
- Open the network settings in the control panel of the PC
- Static IP address for the PC:
192.168.1.3 - Network mask:
255.255.255.0

4 Add the charger to Reduxi
Use these steps to add a new charger or to edit an existing one.
4.1 Basic settings
Log in locally to the Reduxi Configurator on the controller (see Point 3) and press the Add device button.

Below, two buttons side by side: Add device (plus icon, marked with a blue highlight box) and Add strategy (plus icon). Below them two entries: Settings and Profile. The area to the right of the sidebar is empty white.
In the first step (basic settings), select the basic parameters of the device:
- Device type:
EV charger - Type:
OCPP 1.6 - JSON - Name: a name of your choice

Progress bar with three steps: 1 Basic settings (active, black circle), 2 Communication channel (grey), 3 Advanced settings (grey). Heading: Basic settings. Fields: Device type * : empty dropdown; Type * : empty dropdown; Name * : empty text field. Buttons: Back (bottom left), Next (bottom right, dark).
After you have entered everything, press Next.
4.2 Communication settings
The second step sets the communication channel for OCPP.
- Paste the Device identifier from the web interface of the charger into the first field of the communication channel.
- The OCPP 1.6 JSON protocol needs the server OCPP URL. The Reduxi Controller generates it. You can copy the URL directly from the communication channel.
Example URL: ws://10.150.120/ocpp/1.6/json/

Screenshot of the Reduxi Configurator form Communication channel and device configuration. Device identifier *: 1234. Connector *: 1. Charger type *: AC. Energy counter: Default. Allocate power to EVSE when EV is not connected to EVSE: Default. Per phase max. current *: Auto detect from EVSE. Per phase max. current manual override: 32 (hint: In effect when manual override is selected). Forward communication to backend OCPP server: ws://app.eu.tridenstechnology.com/ev-charge/gw-comm/glcharge. Forward measurements to backend OCPP server once every: 30 seconds. Allow new charging session: Forward to backend OCPP server. Controller OCPP JSON 1.6 URL (read-only, with copy icon): ws://10.150.1.120/ocpp/1.6/json. Buttons: Back, Test communication, Next (dark).
4.3 Test communication
Click Test communication at the lower right, below the communication channel fields. It checks that OCPP communication is established. If the test succeeds, click Done: only Done creates the device.

Progress bar: 1 Basic settings (black), 2 Communication channel (black, active), 3 Advanced settings (grey). Heading: Communication channel and device configuration. Fields: Device identifier *: my_station_ID1 (text field being edited, green outline); Connector *: 1; Charger type *: AC; Energy counter: Default; Allocate power to EVSE when EV is not connected to EVSE: Default; Per phase max. current *: Manual override; Per phase max. current manual override: 32 (hint below, small); Forward communication to backend OCPP server: empty; Allow new charging session: Always; Controller OCPP JSON 1.6 URL: ws:// address followed by /ocpp/1.6/json. Buttons at the bottom: Back (left), Test communication (marked with a blue box) and Next (right).
The test returns one of three results:

Go live (Point 5): Check the last measurements in the Reduxi Configurator. Monitor the charger in the Reduxi cloud application.
→ Common issues
| Issue | Solution |
|---|---|
| The charger web interface does not open | The PC and the charger must be in the same network. Set the PC to 192.168.1.3 with network mask 255.255.255.0 and open 192.168.1.2 in the browser. |
| Test communication: the ID of the device is not set or is different | Paste the device identifier from the charger web interface into the first field of the communication channel. |
| Test communication: no device with OCPP 1.6 communication found | Enter the server URL of the Reduxi Controller in the OCPP section of the charger. Click Apply and Restart OCPP. |
| 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. |
Login with admin is rejected |
The password was changed during installation. Ask the installer. The Reduxi account password does not work here. |
reduxi.local does not load |
Your device is not in the same network as the controller. Use the IP address or the tunnel connection. |
| Communication test fails, device shows offline | Check reachability, IP address / port / unit ID, and that the protocol is enabled on the device. |
