Send data from IoT central to Azure Machine Learning Resource

Hi,

I am looking to send data from IoT Central to Azure Machine Learning and wondering what the best way to do it is?

I am trying to send a value, for ex. Temperature degree to a python script to process the data, extract features and then run a machine learning model on it. Then passing the data back to IoT Central dashboard to display the results of Machine Learning.

So far I've seen about making a blob storage and using Data Export in IoT central to send to it and then making the blob storage a dataset in the Machine Learning Resource.

But I am wondering if this is the best way to do it or if there is a more direct way to send the data from IoT Central to Machine Learning?

Thanks!

@yjay-4307 I dont see any direct way to send data to Machine Learning. AFAIK, Data Export is the best approach we have today. Will encourage community to provide any other approaches they've tried.

@AshokPeddakotla-MSFT thanks so much!

And do you know if blob storage is the best place to export to?

In datastore options in ML I see datastore Azure blob storage, file share, Data Lake Storage, SQL Database, PostgreSQL database and MySQL database.
Are any of these better options?

Is it possible to export data from IoT central to these datasores?
On IoT Central I only see Azure blob storage, Event Hubs, Service Bus Queue, Service Bus Topic and Webhook.

Seems only Blob Storage overlaps between them.

Is it possible to use other export options to send to ML such as Service bus or Even hubs?

Thanks again!

Your understanding is correct. Currently, you can only export to the below available destinations.

  • Azure Event Hubs

  • Azure Service Bus queue

  • Azure Service Bus topic

  • Azure Blob Storage

  • Webhook

If you haven't checked earlier, I would suggest you kindly take a look at the documentation Export IoT data to cloud destinations using data export for more details.
