Raw data not showing for IoT Edge device in Azure IoT Central

Question

I'm not seeing any mapped raw data entries for IoT Edge devices, but I do see raw data for devices that aren't IoT Edge enabled.

IoT Edge device with no mapped raw data:

Standard device showing mapped raw data:

Furthermore, if I expand an event that was sent (in this case a property that is being set correctly as I'm showing it in one of the device views), the content is empty - no mapping to the property and no unmodelled data:

Thinking this might be down to something wrong in my code, I ran through the 'Connect an IoT Edge device to your Azure IoT Central application' tutorial which had the same results - no mapped raw data being displayed but the telemetry was getting through and being displayed in a view.

Does anybody have any ideas on what's going wrong?

Answer 1

Hi @Matthew Pass Greetings! I have tested the tutorial link you have shared Connect an IoT Edge device to your Azure IoT Central application and could view the raw data under the IoT Central device pane. Please review the below images.

Scenario 1: No device template assigned

Since there is no device template assigned, the data is categorized as unmodeled data.

Scenario 2: After assigning the device template

I could see the raw data in the appropriate fields. Please let us know if this is not your observation when you tested the edge device by following the steps in the tutorial.

Answer 2

As of today, the raw data started to be displayed.

I've no idea why - I didn't make any changes on my end. I'm hoping it was just a behind-the-scenes update to IoT Central in the region where my application is hosted.
