Abstract:
1. An architecture for an automation system, the automation system used to remotely control and monitor power-consuming devices drawing power from a power line in a building, the architecture comprising: a lookup service maintaining a database of (1) the power-consuming devices including their attributes of device type and physical location, and (2) device objects corresponding to the power-consuming devices including a name for each device object mapped to at least one address; a soft state store managing refresh information, in a persistent state or in a volatile state, for the power-consuming devices and the device objects to be within the predetermined refresh rate threshold; a publication/subscription eventing component enabling subscriptions to events related to changes in the refresh information managed by the soft state store; and, a power line monitor detecting superimposed transmissions from the power-consuming devices on the power line, which signal problems associated with the power-consuming devices.
