Data mapping with Message Template

This video shows how to use the Message Template module in flows to map incoming data into a custom data model. The example uses an OPC UA subscriber as the input source, but the approach works with any source, such as databases, streaming services, or HTTP.

You will learn how to create a structured payload by selecting and renaming properties like name, data type, value, and timestamp using template syntax. The tutorial also shows how to enrich messages with node environment variables such as flow runtime name, flow version, and platform.

By the end, you’ll understand how to design consistent data structures with Message Template for easier downstream processing.
