Time Series Insights <-> Iot Hub Connection - Using DeviceId as Time Series ID

Question

Hello,

I am looking to use Time Series Insights to accept data from an IoT Hub, with the time series ID set to the deviceId that is embedded in IoT Hub events (not present in the JSON message body).

I've tried several ways of encoding this key when specifying the time series ID, attempting to follow the JSON flattening rules. I have tried all of these below, but I still end up seeing the device as 'null' in TSI Explorer.

deviceId
connectionDeviceId
IoTHub.connectionDeviceId
SystemProperties.connectionDeviceId (this is what comes back when using the API to read the data files from blob storage)
$event.SystemProperties.connectionDeviceId

I have perused all the documentation on this topic and it seems the most basic use case for connecting these two services is not specified. Perhaps I've missed something.

Thank you.

Hello @KileD951 ,
I have confirmed that you would need to use iothub-connection-device-id as TSI ID like documented here:
