The present disclosure describes smart meter modules. A smart meter module may include a support frame and an outer cover. The support frame includes a top mounting plate, a bottom mounting plate, and an inner bracket between the top and bottom mounting plates and coupled thereto. The top mounting plate is spaced apart a distance from the bottom mounting plate to form an interior space of the module. The inner bracket has a central aperture that is generally perpendicular relative to the top and bottom mounting plates and configured to receive and secure a smart meter within the interior space of the module. The outer cover is configured to be secured to the inner bracket and sized to extend circumferentially around the interior space of the module. One or more elongated mounting apertures in the bottom mounting plate are configured such that the smart meter module can be secured to the top of a mounting pole. Smart meter module assemblies are also provided.

A baseboard management controller (BMC) installed in a server or other hardware device may perform operations to monitor and safeguard metering data for one or more hardware component of a server that includes the BMC. The BMC may periodically transmit a metering data message over a network to an event destination, where the metering data message includes the utilization levels of the hardware component during a period of operation. In response to detecting a loss of communication with the event destination, the BMC may perform lossy compression of the monitored utilization levels for the hardware component, wherein the lossy compression produces a utilization value that is representative of the monitored utilization levels, but uses less data storage capacity. The utilization value may be transmitted to the event destination instead of the monitored utilization levels in response to determining that communication with the event destination has been reestablished.

A system is disclosed which eliminates problems caused by surges of electric energy which is generated on a utility customer's property and which is fed back onto a utility-owned service line by maintaining a minimum utility provided percentage (MUPP) of power being provided onto a customer-owned dead-end service line. Where the electric energy generated by a utility customer is incrementally excluded from the customer-owned dead-end service line through a plurality of contactors which are controlled by a 120 volt command line.

Methods and systems of electric vehicle charging management for community with energy monitoring are provided, which are suitable for a community including a plurality of dwellings, and each dwelling has an electric vehicle charging station connected to a server through a network. First, a current transformer is used to measure the main power lines of the community to obtain a current consumption of the community, where the main power line is tapped into a plurality of auxiliary power lines to provide electricity for each of the dwellings. The server determines whether the current consumption of the community meets a predetermined condition of the community, and if so, the server executes at least one energy management scheme, wherein the energy management scheme records a power distribution logic, which is used to control the charging operation of the electric vehicle charging station corresponding to the respective dwelling via the network.

An electrical panel or an electrical meter may provide improved functionality by interacting with a smart plug. A smart plug may provide a smart-plug power monitoring signal that includes information about power consumption of devices connected to the smart plug. The smart-plug power monitoring signal may be used in conjunction with power monitoring signals from the electrical mains of the building for providing information about the operation of devices in the building. For example, the power monitoring signals may be used to (i) determine the main of the house that provides power to the smart plug, (ii) identify devices receiving power from the smart plug, (iii) improve the accuracy of identifying device state changes, and (iv) train mathematical models for identifying devices and device state changes.

A method for transmitting data from a management entity in a communication system further comprising at least one data concentrator device to which smart electricity meters are attached via a first powerline communication network, each data concentrator device being connected to the management entity via a second communication network. Said smart electricity meter receives, coming from the management entity, via the first powerline communication network, a message indicating that a transfer of data is pending with the management entity. Said smart electricity meter comprising a wireless communication interface adapted to communicate via a third wireless local communication network with a residential gateway connected to the management entity via a fourth communication network, said smart electricity meter obtains said data from the management entity via the third wireless local communication network.

An electric meter includes a meter shell configured to be within an outer utility box. A meter socket and blades are for coupling to openings of the socket. The openings include utility-side and premises-side openings for the blades to extend into. A meter processor is coupled to measurement circuitry, and to a communications unit including a transceiver. A gas sensor is positioned proximate to the blades for sensing ≥1 gaseous compound product resulting from an arc discharge across air involving the blades. During operation of the electric meter, responsive sensing a presence of the gaseous compound product, the gas sensor generates an output signal. Responsive to the output signal being above a predetermined threshold level, the electric meter triggers an alert signal that is transmitted to an advanced metering infrastructure (AMI) which indicates an identity of the electric meter and that the electric meter had experienced the arc discharge.
