Abstract
Methods, systems, and apparatuses are described herein for the automatic determination of a state of a consumer electronic device via power monitoring. A switching device receives a power signature signal associated with a consumer electronic device. The power signature signal is compared to one or more reference power signatures. A determination of whether a level of similarity between the power signature signal and the one or more reference power signatures meets a threshold condition is made. If so, a determination that the consumer electronic device is in a state associated with the one or more reference power signatures is made. In response to determining that the level of similarity between the power signature signal and the one or more reference power signatures does not meet the threshold condition, a corrective action is performed. In another aspect, a reference power signature is calibrated for a consumer electronic device.
