Namespaces

namespaces allow you to group topics logically, such as by area, line, or machine you can subscribe to namespaces to receive updates on all subtopics under them this is especially useful when using marketplace applications or custom flows that publish to dynamic or unknown topics (topic names are generated programmatically) by adding the relevant namespace, the topic registry will track these topics to manage namespaces, click add namespace on the marketplace or flows page in the add namespace dialog, enter the namespace you want to subscribe to for instance, to track topics related to a specific device, add its namespace (e g , devicehub alias devicename or devicehub raw\ deviceid ) to receive data updates on all associated subtopics once added, the topic registry will begin tracking all subtopics under it
