Question

How do I configure Power BI to work with real-time streaming data from an IoT device?
I need to configure Power BI to visualize real-time streaming data from an IoT device. The setup should ensure minimal latency and continuous data updates without requiring manual refreshes. What is the best approach to achieve this using streaming datasets, Power Automate, or Azure Event Hubs while maintaining performance and scalability?

Answer 1

To configure Power BI for real-time streaming data from an IoT device, you need to establish a low-latency data pipeline that continuously updates without requiring manual refreshes. The best approach depends on the data source, volume, and update frequency.

1. Streaming Dataset in Power BI – Use Power BI Streaming Datasets for real-time updates. Push data from your IoT device to Power BI REST API or Azure Stream Analytics, which can route data directly to a Power BI dashboard. This method ensures real-time visualization but stores only limited historical data.

2. Azure Event Hubs + Stream Analytics – For handling large-scale IoT data, Azure Event Hubs can ingest data from IoT devices, and Azure Stream Analytics can process and push the results to Power BI's push dataset or Azure SQL Database for further analysis. This method is scalable and reliable for enterprise use cases.

3. Power Automate for Scheduled Updates – If real-time updates are not critical, Power Automate can periodically push IoT data to Power BI datasets stored in Azure SQL, Dataverse, or SharePoint. This approach works well for near-real-time scenarios with moderate update frequency.
