Reduxi With Voltie EV-Charger
Integrate Voltie chargers with Reduxi via Wi‑Fi and the Voltie platform using the OCPP protocol. Maximal flexibility and possible cost reductions of up to 30%.
1 Technical documentation
Manufacturer documents and further information:
- Voltie Quick start – Installation files, videos for installing the charger, app registration, Wi‑Fi connection and installer mode.
- Voltie technical data sheet – Technical data of the charger.
- Open Charge Alliance – OCPP specification.
2 Required equipment
- Voltie EV charger, installed and commissioned
- Voltie app on a smartphone: registration and Wi‑Fi connection of the charger
- Wi‑Fi network with a stable internet connection
- Reduxi Controller in the same network, with a static IP address
- Laptop or tablet with internet access to configure the device in Reduxi
3 Set up the Voltie charger
3.1 Voltie app and Wi‑Fi connection
Register the charger in the Voltie app and connect it to your Wi‑Fi network. The Voltie platform (the app) is used for the setup. The steps are shown in the Voltie videos on the Quick start page.
3.2 Installation
Install the charger as described on the Voltie Quick start page. Voltie lists the OCPP protocol as one of the integration options of the charger.
4 Log in to the Reduxi web interface
You can open the Reduxi web interface in two ways:
http://reduxi.local. You can find the controller's IP address in your router's device list or in the Reduxi app under Reduxi devices.admin · Password: admin (factory default)5 Add the Voltie charger to Reduxi
Use these steps to add a new Voltie charger or to edit an existing one.
5.1 Basic settings
Log in locally to the Reduxi Configurator (see Point 4) and add a new device by clicking the Add device button.
In the first step, define the basic settings:
- Device type:
EV charger - Type:
Voltie - Name: a name of your choice
Press Next.
5.2 Communication settings
The second step sets the communication channel for OCPP. Define the Device identifier first. You can choose it freely.
For the OCPP JSON 1.6 protocol, a URL is needed. The Reduxi Controller generates it automatically. Add /Device ID at the end of this URL.
| Parameter | Value |
|---|---|
| Device identifier | A name of your choice, for example my_station_ID1
|
| URL | The URL generated by the Reduxi Controller + /Device ID
|
| Example | ws://192.168.1.200/ocpp/1.6/json/my_station_ID1 |
5.3 Enter the URL on the charger
Enter the complete URL, including the Device ID, as the OCPP server address of the Voltie charger. The Device ID must be identical to the Device identifier in Reduxi.
5.4 Test communication
Click Test communication at the bottom of the wizard. It reads the Voltie charger once and saves nothing. If the test succeeds, click Done: only Done creates the device.
6 Check the readings
6.1 Last measurements
After communication is established, check the values under Devices in the Reduxi Configurator.
6.2 Enable control by Reduxi
For control by Reduxi, set the control type of the device to AUTO under Devices in the Reduxi Configurator. Only then do strategy commands affect the charger.
To reduce energy costs with dynamic prices and dynamic tariffs, define a strategy as described in Strategies for Reduxi controller.
✓ Summary
Preparation (Points 1–2): Read the Voltie documents and prepare the equipment, including a static IP address for the Controller.
Voltie charger (Point 3): Register the charger in the Voltie app and connect it to Wi‑Fi.
Add to Reduxi (Points 4–5): Log in to the Reduxi Configurator, add the charger with OCPP JSON 1.6, enter the URL on the charger and test the communication.
Go live (Point 6): Check the readings and set the control type to AUTO.
→ Common issues
| Issue | Solution |
|---|---|
| The charger does not connect to the Controller | Check that the URL on the charger ends with the Device ID and that the Device ID equals the Device identifier in Reduxi. Check that the Controller has a static IP address. |
| The charger lost its Wi‑Fi connection after a router replacement | Repeat the Wi‑Fi setup in the Voltie app. |
| 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. |
