Monitoring and controlling electrical loads is crucial for demand-side energy management in smart grids. Home au-tomation (HA) protocols, such as X10 and Insteon, have pro-vided programmatic load control for many years, and are be-ing widely deployed in early smart grid field trials. While HA protocols include basic monitoring functions, extreme bandwidth limitations (<180bps) have prevented their use in load monitoring. In this paper, we highlight challenges in d
