PowerBI showing telemetry of past ten minutes, always!

PowerBI in the browser is an easy and fast reporting service which is a great addition to Azure IoT. In just minutes you can build charts and dashboards.

I demonstrated this in part 3 of this series of blogs about implementing IoT in Azure.

But I was missing the ‘sliding behaviour’, the charts I created showed all telemetry. And with all I mean from the very first telemetry passed to the latest one.

In this blog, I will show you how to tweak the dashboard a little bit to get that real-time behaviour of showing only the data of the past hour, day or 10 minutes.

Adding the power of BI to your IoT Hub

Once you are using Azure an IoT Hub, you are looking for ways to do something meaningful with the telemetry coming in.

You can try to build your own dashboards in a website eg. but you can also try to show the data using PowerBI.

In this blog, we will look at how to show some nice charts with live data.
