AWS IoT SiteWise now supports null and NaN data types

Today, Amazon Web Services, Inc. announces that AWS IoT SiteWise now supports NULL and NaN (Not a Number) data of bad or uncertain data quality from industrial data sources. AWS IoT SiteWise is a managed service that makes it easy to collect, store, organize, and analyze data from industrial equipment at scale. This new feature enhances the services capability to handle a wider range of data, improving its utility for industrial applications.

With this update, AWS IoT SiteWise now collects, stores, and retrieves real-time or historical NULL values for all supported data types. It also supports NaN values of double data type. Capturing NULL and NaN data is critical for various industrial use cases, including compliance reporting, observability, and downstream analytics, while also simplifying data set conditioning and cleaning for advanced analytics and machine learning applications.

This new feature is available in all AWS Regions where AWS IoT SiteWise is available. To learn more about data ingestion and processing data quality on AWS IoT SiteWise, see AWS IoT SiteWise Documentation.
