Need Help : Azure Percept to IOT Hub to Streaming Dataflows in Premium Workspace

[Celwood]

I have an Azure Percept streaming data through an IoT hub.
I connected to the IoT hub in the streaming dataset interface but in the screenshot below, the "Neural Network" is an array.
How do I go about breaking out the parts of the array so I can use them with the other blocks like aggregate, join etc?

Hi @Celwood ,

Microsoft Power BI is a data visualization tool that you can use to perform self-service and enterprise business intelligence (BI) over large data sets.

According to your description, the "Neural Network" array is configured in Azure portal->IoT hub, not through the Premium Workspace environment.

For more details, you can read related document link:

Hi @v-henryk-mstf  Henry,  I viewed the document you provided.  I have followed that tutorial before and it uses Stream Analytics to select * fields from the data stream and pass onto PowerBI.  

The streaming dataflow documentation here : https://docs.microsoft.com/en-us/power-bi/transform-model/dataflows/dataflows-streaming
has a diagram that shows that Azure Stream Analytics is the streaming engine.

I was hoping that I could use the same Stream Analytics Query langauge commands inside of the PowerBI streaming datasets interface.

What I plan on doing now is to connect IoT HUB to Stream Analytics, parse out the fields, then connect to streaming dataflows (with stream analytics as the engine), but this seems redundant to pass through the stream analytics engine twice.
