Managing the owner side

The ProvisioningClient instance allows you to create a GUI for the owner-side application that can be used to configure your network. When the device-side interface has requests, the owner side has corresponding events. The following events can be subscribed to, so as to listen for incoming questions from the provisioning server:




This event is raised when the owner needs to decide if a third party is allowed to subscribe to the device's presence or not.


When the provisioning server needs to ask the owner if a third party is allowed to read one of its devices, this event is raised.


When a new control operation is attempted, this event is raised to allow the owner to decide if it's allowed or not.


Note that the owner does not need to be online when the device asks the provisioning server a question. The provisioning server keeps the message and sends it to the owner when the owner gets online.
