📝 Blog Post: Read more at Querying Azure Digital Twins with PowerBI
An example showing how to query Azure Digital Twins from within PowerBI. You could use this to query the current state of your IoT devices, for example, to use the Anomaly Detector cognitive service to check the state of outliers.

- Create an Azure Digital Twin
- Give yourself access to the data plane - add some example data - the Azure Digital Twins explorer example data is a good start.
- Create a virtual environment for your Python setup, e.g.
python3 -m venv .venv - Install the requirements
pip install -r requirements-dev.txt - Copy the path to your venv
- Enable python scripting in PowerBI
- Log in to Azure on the CLI with
az login - Import the powerbi-query.py as a PowerBI datasource
query_expression = "SELECT * FROM digitaltwins"
query_result = service_client.query_twins(query_expression)
twin_list = pd.DataFrame(query_result)
The example query I provide in the query_expression variable will allow you to query the twin graph - and you can use the Azure Digital Twins query language to build on this. Each individual pandas dataframe will appear as a data set in PowerBI.
You should see something like this...
- Using Python as a data source is only refreshable on PowerBI Desktop, or by using an on-premises data gateway in personal mode.
