Abstract
An architecture for an automation system is disclosed that includes look-up services, a soft-state store, and a publication/subscription eventing component. The look-up services maintain a database of a number of devices to be controlled and monitored, and a database of a number of device objects corresponding to the devices. The services can be divided into attribute-based and name-based services. The soft-state store manages variables regarding the devices and the device objects, including heartbeats. The eventing component enables subscriptions to events related to changes in the variables. The architecture can include management daemons, such as a monitoring daemon that detects problems with power line devices.
