Abstract

A mountable wall receptacle including one or more current sensors and power-line communications circuitry is described herein. In one exemplary, non-limiting embodiment, the mountable wall receptacle includes power-line communications circuitry, one or more current sensors, a power source, and one or more internal contacts. The wall receptacle is capable of monitoring and recording, using the current sensor(s), an amount of current or energy provided to an accessory device plugged into one or more outlets in communication with the one or more internal contacts. A user device is able to obtain the recorded amount of current or energy from various access points within a residence using one or more power lines located at the residence. The power lines enable the user device to communicate with the wall receptacle using the power-line communications circuitry therein.
