Introduction

This article contains instructions on how to configure ThingsBoard IoT platform and connect Teltonika-Networks devices. ThingsBoard IoT platform is an open-source IoT platform for data collection, processing, visualization, and device management. It enables device connectivity via industry standard IoT protocols - MQTT, CoAP and HTTP and supports both cloud and on-premises deployments. ThingsBoard combines scalability, fault-tolerance and performance so you will never lose your data.

Configuring ThingsBoard IoT platform

The goal of this tutorial is to demonstrate the basic usage of the most popular ThingsBoard features which helps monitor Teltonika-Networks devices. First, you need to login into the platform. Next, you will see an overview window, scroll down to Device management section or simply click on the Device group in the navigation menu.

  1. Click on one of the marked in red buttons in the Device groups overview page. In this page you can also add additional device groups in order to distinguish different devices with unique data flows.
  2. Click marked "+" buttons to add new device to the group.

Credentials type: Access token (HTTP protocol)


  1. Enable Add credentials option.
  2. Set desirable Access token.
  3. Click Add button to save changes.

Credentials type: MQTT Basic


  1. Enable Add credentials option.
  2. Choose Credentials type:MQTT Basic.
  3. Set username which will be used in MQTT authorization.
  4. Set password which will be used in MQTT authorization.
  5. Click Add button to save changes.

Preparing data source

Different data streams can be selected depending on the device's supported functionality's. In this example we will be using Modbus TCP slave with native Modbus TCP master functionality.

1. First, change WEBUI mode from basic to advanced.

Configuring data to server with HTTP protocol

After configuring the data source, you can add a data sender configuration. Data sender functionality is located Services → Data to server. You can add data sender by clicking Add button.

  1. Set name for the Data sender.
  2. Set desirable name for your data variable. Make sure that your chosen parameter is shown below JSON format field.
  3. Paste connection string with your own Access token.
  4. https://thingsboard.cloud/api/v1/YOUR_ACCESS_TOKEN/telemetry
  5. Add value to Custom header.
  6. Content-Type:application/json

Configuring data to server with MQTT protocol

After configuring the data source, you can add a data sender configuration. Data sender functionality is located Services → Data to server. You can add data sender by clicking Add button.

  1. Set name for the Data sender.
  2. Choose MQTT protocol.
  3. Set desirable name for your data variable. Make sure that your chosen parameter is shown below JSON format field.
  4. Enter thingsboard.cloud as a host.
  5. Paste in MQTT topic.
  6. v1/devices/me/telemetry
  7. Enable Use credentials option. Enter configured username and password from ThingsBoard IoT platform.

Adding widget to the dashboard

The collected data can be displayed using various a widgets. To create one you should be able to see gathered data in the Latest telemetry section. To access it you should follow these steps:

  1. Click on the configured device.
  2. From the pop-up menu select Latest telemetry option. There you should see collected data.
