Azure EventGrid namespace MQTT Explorer

The EventGrid namespace now offers a full vanilla MQTT Broker. This is a fine solution for connecting devices in a secure way to the cloud with custom MQTT topics. It can even provide Device-to-Device communication out of the box.

You will soon realize this isn’t a replacement for the well-known Azure IoT Hub. This tool combines those custom MQTT topics with that much-requested device-to-device connectivity.

Just create the MQTT broker, enter the right information about clients, client groups, topic spaces, and permission bindings and you are good to go.

Unfortunately, the Azure portal experience is a bit poor, there is not that much tooling available to make your MQTT broker life easy.

So, I am sharing with you some extra tooling.

I already shared a library that provides an overview of all topics per registered client.

Another omission is that there is no explorer tool to check the incoming data.

That’s why I created an explorer like this:

Based on all incoming messages, a list of MQTT topics is built up and the messages are shown. In real-time. As a string list or a chart.

Let’s see how you can get it to run and what it offers to you.
