The NuGets Waher.Networking.XMPP.Control[.UWP] provides a ControlServer class that helps an actuator to publish its control parameters on the XMPP network. It also contains a Control Client class that can be used to set control parameter values on other entities on the XMPP network. As with the sensor interfaces, the control classes use interoperability interfaces defined in the IEEE IoT Harmonization working group. (These sensor data interfaces are in turn based on the legacy interfaces defined in XEP-0325.) The control interfaces support:

• Simple atomic set operations
• Complex group set operations
• The representation that is loosely coupled and does not require interface changes for new types of devices
• Interfaces that allow for sufficient metadata to be included in result sets for it to be possible to use in both M2M and H2M interfaces
• Interfaces that support localization
• Secure distributed transactions
• The limitation of requests (provisioning)
