An intelligent electronic device with multiple functionalities that may include multiple secure accesses includes a sensor coupled with a processor. The sensor may sense electrical parameters in an electrical circuit and generate signals indicative of the electrical parameters for the processor. The processor may be configured to concurrently operate multiple intelligent electronic device functionalities. The intelligent electronic device functionalities may each include one or more functions. The functions within one of the intelligent electronic device functionalities may be mutually exclusive. Secure access to one or more of the intelligent electronic device functionalities may be enabled by entry of a user identification.

Multi-function intelligent electronic device with secure access

Systems and methods for grouping mesh networks. Mesh networks enable energy data to be transferred from an energy sensing device to a destination device using various networks and reduces the need to install metering stations. Embodiments of the invention join or group mesh networks that otherwise are not able to communicate. The connections between the grouped mesh networks can be passive using directional antennas or passive antennas or active using higher power RF devices, solar repeaters, mobile mesh devices, etc. The energy data is routed in a smart manner, by performing load balancing at gateways, by monitoring the signal to noise ratio of available communication paths, etc. Mesh clusters can also be created to define low power clusters, address blocking clusters, and frequency based clusters. Grouping clusters facilitates the efficient transfer of energy data from an energy sensing device to a energy management station.
