Subscribing to Resource changes from a web application

Device Management Connect provides connectivity to devices running Device Management Client. In addition to read and write operations towards devices, it offers a subscribe method to observe changes in device Resources.

To minimize the network traffic, the client does not start sending notifications of Resource changes automatically. Instead, the web application needs to subscribe to the device Resources.

You can also reduce the network traffic by using the Auto-observation feature.

See Presubscriptions on how you can utilize Device Management Connect.
