Time Series Insights Error - Don't receive the messages from event hub

Question

Hello, I am following this tutorial:

https://learn.microsoft.com/en-us/azure/digital-twins/how-to-integrate-time-series-insights#set-the-twins-event-hub-connection-string

I did all the step in the tutorial.

I can see the data sent successfully from Digital Twin to ProcessDTUpdatetoTSI.cs function, Event Hub namespace ( both the twin hub and time series hub). ( I attach images for each resource below)

But I don't see any received message on the Time series environment.:

Also in Time Series Insights Explorer, I don't see the expected twin device id on the left but only null:

Do you think I miss any step? Or Do I need to change everything on Function app to deal with my data ( which include 4 feature: windDirection, windSpeed, Current, Power) instead of only temperature ?

For more information, I did this tutorial to send data from my device to Azure DT(https://learn.microsoft.com/en-us/azure/digital-twins/how-to-ingest-iot-hub-data)

Hello @Anh Dinh,

Do you only want to use Time Series Insights for storing Azure Digital Twins history data?

Are you aware Azure Time Series is being deprecated in 2025?

The Time Series Insights (TSI) service will no longer be supported after March 2025. Consider migrating existing TSI environments to alternative solutions as soon as possible.

The Time Series database functionality offered by TSI is replaced by Azure Data Explorer (plus many more features). Be aware the visual interface is offered with this SDK. But you can also check out the Azure Data Explorer dashboard or the Grafana integration.

Next, Azure Digital Twins now offers out-of-the-box history data export toward Azure Data Explorer in a more elaborate way:

Just follow the instructions of the wizard and both EventHub and table construction are taken care of.
