Controlling Devices in V-VAC Using Rapidon | IoT MQTT Dashboard for Real-Time Data

In this DIY project, we’ll use the VOLKKOMMEN® Rapidon Wi-Fi module to connect sensors and control devices through the V-VAC IoT platform. With just a few simple steps, you can send real-time data to the cloud and visualize it on a live dashboard — no complex coding or setup required!

V-VAC lets you easily create custom widgets, monitor live readings, and control devices remotely using MQTT communication. Whether it’s temperature monitoring or simple automation, this project shows how quickly you can bring your IoT ideas to life.

By the end, you’ll have a working IoT dashboard that displays sensor data and allows one-click control of connected devices — all powered by Rapidon Wi-Fi and V-VAC.

Hardware Components

1. Rapidon Wi-Fi (VOLKKOMMEN®)
2. 5V, 1A DC Power Adapter (for Rapidon Wi-Fi)
3. Laptop / PC for configuration
4. Wi-Fi Router / Access Point
5. Screwdriver and wire stripper for connections
6. Connecting wires

Software Components

1. Web Browser (Google Chrome / Edge)
2. Wi-Fi Access Credentials (SSID and Password)
3. Network Analyzer Tool (to find the device — IP optional)

Power off both devices before wiring.

LED Status Indications

1. White: Booting
2. Cyan fading: Scanning Wi-Fi
3. Green: Connected to Wi-Fi
4. Purple: Configuration mode active

You can display and analyze this data using the VOLKKOMMEN V-VAC Platform: V-VAC

Steps to Connect V-VAC :

1. Log in to your V-VAC account. (Create a new account if not signed up already.)
2. In the Devices section add a new device.
3. Select common device and enter the details of the device.
4. Copy the Device Token and paste it in the MQTT section of theRapidon Wi-Fi Web Interface.

For further details check out (How to connect to V-VAC).

Enter Configuration Mode.

1. Press the Config button on the Rapidon Wi-Fi device.
2. The Status LED will turn purple, indicating that the device is now in configuration mode.

Connect to the Rapidon Wi-Fi Network.

1. On your laptop or smartphone, open the list of available Wi-Fi networks.
2. Select:

SSID: Rapidon Wi-Fi (Your_Device_Name)

1. When prompted for a password, enter:

Password: 12345678

1. Once connected, keep this network active — it will allow access to the configuration interface.

Open the Configuration Page.

1. Open a web browser (Google Chrome or Edge recommended).
2. In the address bar, type:

192.168.4.1

1. Press Enter — the Main Menu Page will open.
2. Click on “Configure Wi-Fi” to proceed to the network settings screen.

Add Your Wi-Fi Details

1. In the Wi-Fi Settings page, enter your router details:
2. SSID :Your_WiFi_Name
3. Password :Your_WiFi_Password
4. Click Save Settings.
5. The device will automatically restart and connect to your Wi-Fi network.

💡 Tip: Once it reconnects, the Status LED will change from blue (not connected) to green (connected).

Find the Device IP Address

1. Open your Wi-Fi router’s connected device list or use a network scanner app (like Fing or Advanced IP Scanner).
2. Locate Rapidon Wi-Fi in the device list — note down its IP address.
3. Use this IP to access the Rapidon Wi-Fi web interface for further configuration.

Access the Rapidon Wi-Fi Web Interface.

1. Open a web browser and enter the IP address you found in Step 3.
2. The login page will appear.
3. Enter the default credentials:

Username: User@volk.com

Password: Pass@123

1. Click Login to access the main dashboard.

Open the Setup Menu.

1. Once logged in, you’ll see the Main Menu.
2. Click on the “Setup” option.
3. This will open the Cloud Settings Page.

Configure MQTT Parameters.

Fill in the following details according to your cloud or broker settings:

Parameter : Value

Server : data.volkkommen.com

Port : 1883

Username :from V-VAC platform (Devices → Setup)

Password :from V-VAC platform (Devices → Setup)

Topic :from V-VAC platform (Devices → Setup)

example → Topic : f898f4a51628f4eb replace it with Device token from V-VAC platform (Devices).

data-1 and data-2 : Required interval to send data.

Device Name : can be modified for easier identification.

Note : The device name should be less than 15 characters and avoid using spaces between characters

Save and Apply Settings

1. Review all fields carefully.
2. Click “Save” to apply the settings.
3. Once successful, you’ll see green LED indicating an active Wi-Fi and MQTT connection.

1. In Dashboard section you can configure widgets for your required data.
2. Click “Create Dashboard”.
3. Give your dashboard a name (e.g., Smart Sensor Dashboard).
4. Click the 3rd icon in the dashboard to open the dashboard.
5. Inside the dashboard editor, click “Edit” and click "Add Widget" to add new widgets.
6. In the selection menu choose the Push Button widget.
7. Link widget to a Device telemetry key (the data your device sends).
8. After customizing your widget, click the Show on Dashboard button to display it on the dashboard.
9. To save your changes, click the Save button at the top-right corner of the dashboard.
10. You can now remotely control the device from anywhere around the world.
