DeviceCapability

A DeviceCapability connects a Device and a Capability. This is necessary because different devices can have the same capability, but with slight differences e.g. regarding the actual values of some properties.

For example, a recorder A can have a provisioningTime of 5 seconds for the capability of type “Record” while recorder B has a provisioningTime of 10 seconds. The value is important to control the devices when performing a record command, but is in most cases irrelevant for the chosen device for an action.

Properties

Property	Possible Values	Example	Description
id	string	VCR-0B	External ID of the DeviceCapability.
capability	Capability	see Capability.	The Capability that is assigned to a Device by this DeviceCapability.
config	string (JSON)	CODE `{ "nonBlockingProvisioningTime":5 }`	The values for the properties defined in the capability.
deviceId	string	VCR-0B	ID of the device this DeviceCapability refers to
capabilityId	string	VCR-Wj	ID of the capability this DeviceCapability refers to
