I found some tutorials that show a Simple "Device Monitoring" solution using IoTHub -> StreamAnalytics -> PowerBI here and here.
Tried setting up the System as said just use a different Accounts for Azure (private MSDN account) and PowerBI (Work Account), but then i found the following quote.
Note: Make sure that you are logged into the Azure portal with the same account that you use for Power BI when you click Authorize.
Now I can not use the same Account for both because I do not have an active subscription on my work account. And I can not create a PowerBI account with my gmail address (I got no idea why)
Is there any way I can still get the Stream Analytics connected to my PowerBI Account? And if not is there any alternate Dashboard inside Azure which I can use for a Proof of Concept?
