System and methods in which endpoint control devices, such as, for example, switches and wall sockets, are arranged to monitor the power used by the controlled load as well as the power-factor of the load. In one embodiment, the monitored power and power-factor of a controlled device is fed back to a central point within the premises and then sent on to a more global monitoring point. In one embodiment, the endpoint device can send power parameter data to another location and receive instructions as to maximum allowable loads for a given power parameter or power-factor.
