MQTT Publisher integration with Azure IOT Hub as subscriber

Question

MQTT Publisher integration with Azure IOT Hub as subscriber

Treesa George 21

I have a device which supports MQTT protocol. But the problem is I don't know how I can publish the topic messages to a broker because I don't have subscriber and a broker.

So, my question is can I use Azure IoT Hub as subscriber? Could you please advise on the MQTT Broker that can be used for integration for this POC?

The goal is it get that published topics daily and use it for analytics using PowerBI.

Please answer my question and share some use cases or documentation links. Thanks

IoT Hub is not a full-featured MQTT broker. It doesn't have all the features a generic MQTT broker has. You can read about the MQTT support on this page.

As it stands, your question is quite broad and doesn't focus on a specific issue. A lot of information is available on IoT Hub, PowerBI and sending/receiving telemetry. If you still have questions after studying that information, please feel free to add more detail and focus! There are some tips on how to do that here.

Hello @Treesa George ,

While IoT Hub is not a fully featured MQTT Broker, you can use any standard MQTT 3.1 client to publish messages to IoT Hub specific and pre-defined topics as well as subscribe to receive messages (commands) for the device.
The following chapter on MQTT support in the IoT Hub documentation describes several ways of how to connect a device with MQTT as well as the available topics for bi-directional communication.
To consume messages sent from a device to the cloud, your backend service needs to support AMQP to consume messages from the built-in endpoint as described in the docs. You can either use one of the SDKs or product integrations, e.g., Azure Functions, Azure Stream Analytics.

A simple setup could be your device with an MQTT client publishing messages to IoT Hub, Azure Stream Analytics what is consuming these messages and sends the processed output to Power BI. There is a brief tutorial using an online Raspberry Pi simulator. If you connect your MQTT device as described in the docs and replace the Raspberry Pi Simulator, it should match your description.

Your MQTT client can directly publish messages to your IoT Hub instance. If you need an additional broker on premises, I recommend to have a local client subscribe to the relevant topics on the local broker and forward the processed message to IoT Hub. Ideally your client uses one of the existing IoT device SDKs as these make life easier.

@chbeier thanks for your advice. Just wanted to check MQTT client publishing messages via broker to IoT Hub right? I have come across few brokers such mosquito and hive MQ.
