You've likely already heard about Cogent DataHub and it's MQTT integration capabilities.  The DataHub MQTT Client goes beyond just generically connecting to MQTT Brokers by providing smart connectors for Azure IoT Hub, Google IoT and Amazon IoT Core MQTT Broker services.

The following short video blog demonstrates step-by-step how to easily configure the DataHub MQTT Client for publishing OPC UA and OPC DA data from DataHub to the Azure IoT Hub, as well as, pushing data from the many other data sources supported by Cogent DataHub (such as ODBC, DDE, Modbus and more).

In this video you will learn how to setup the MQTT Client feature of Cogent DataHub for the following functions:

  • Connecting OPC UA and DA data sources with the Cogent DataHub
  • Publishing OPC UA and OPC DA data available in Cogent DataHub to the Azure IoT Hub

Just to summarize, in this video, I've shown you:

  1. How to configure an OPC UA client connection to an OPC UA server
  2. How to configure an OPC DA client connection to an OPC DA server
  3. How to configure an MQTT Client publish (pushing data) to the Azure IoT Hub (MQTT Broker)
    1. Downloading Azure Device Explorer (Downloadable Here)
    2. Configuring the Azure IoT Hub section of the DataHub MQTT Client feature
  4. How to monitor the published data in Azure IoT Hub using Azure Device Explorer

Don't forget to read our new features blog post to learn about the other great features in DataHub V9 or visit the Cogent DataHub website for full details of the release.

Microsoft has recently discontinued the Device Explorer used in this video.  An alternate method is available for users who do not have this Device Explorer.

Are you ready to start integrating your systems with the Azure IoT Hub?
