A power monitoring device (PMD) can perform real-time remote managing, status reporting and analysis on the health/condition of equipment connected to the PMD. For example, a PMD provides data such as whether the equipment connected is idling, fully operating, malfunctioning, etc. The PMD can turn the power on/off, trigger system alert, and perform time-delayed or special profile programming to manage and monitor equipment usage. A power signature identification capability can identify what equipment such as monitor, laptop, lighting equipment, etc., are being connected. A configuration can be used by the power management device based at least in part on the waveform information (e.g., device model, activity status, etc.). Real-time diagnosis and collection of energy consumption and usage pattern can be aggregated for planning and management. Asset management can be enabled by discovering which models of devices are active and connected to a predetermined power management device.
