1. A computer-implemented method of identifying an anomaly in an operation of a device, comprising:
measuring voltages of lead pairs connected to respective prongs of an electrical plug;
determining, based on the measurement, a current power draw signature of the device based on an analog waveform data stream of the device;
digitizing the analog waveform data stream;
comparing, by an electrical power analyzer coupled to an electrical outlet, the current power draw signature of the device with a known power draw signature of the device;
determining whether at least one anomaly is present in the current power draw signature indicating an imminent failure of the device; and
generating a warning in response to determining the at least one anomaly is present in the current power draw signature.
