Abstract: A device-agnostic collector is capable of accepting information pushed from a node for aggregation and subsequent transmission to the head end server. As a receiver of pushed information, the device-agnostic collector does not require information about the type of meter at the node or the type of data structures transmitted by the node.

Another device may allow users to override some instructions. Messages may be provided to users to request the cessation of energy consumption; the users may, but need not comply.

Abstract: When a metering coupled to a network loses its primary power source and has a secondary power source, such as a super-capacitor, it recognizes and reports a power outage. In this case, the head end server may verify the power outage report by querying through the downstream nodes coupled to the network about the power outage. When a node loses its primary power source and has no secondary power source, it will fail to make a regularly scheduled report at the appropriate time. Consequently, the head end server verify the power outage by polling downstream nodes coupled to the HAN about the power outage to deduce whether a power outage.
