    摘要： A method, system and device for synchronizing a time period over which energy measurements are accumulated for an energy monitoring system including a plurality of energy monitoring devices is described. The method comprises transmitting a first radio frequency packet from a time reference device via at least a first and a second of the plurality of energy monitoring devices to a third of the plurality of energy monitoring devices. The method further comprises adjusting a time register within the third energy monitoring device based on the reception of the packet. The method further comprises accumulating a measure of energy consumption by the third energy monitoring device of a load coupled with the third energy monitoring device. The method further comprises transmitting the measure of energy consumption from the third energy monitoring device via at least a fourth and a fifth of the plurality of energy monitoring devices to a data aggregation device. The method further comprises identifying by the data aggregation device an aggregate measure of energy consumption consumed by the load over the time period.

    摘要： An energy monitoring device including procedures for secure communication of data from the device is disclosed. The energy monitoring device includes a public/private key pair used to encrypt and/or digitally sign communications by the device. This allows the receivers of these communications to authenticate the communications to ensure that the device and/or communications have not been compromised. The energy monitoring device is further capable of communications via an ad-hoc “mesh” network, thereby facilitating communications among devices which are substantially inaccessible due to either physical or economic limitations.
