## Summary

Joe Bamberg, who worked in Analog Devices' energy metering group and later at Sense, explains the evolution of power monitoring from electromechanical meters to modern smart meters using fixed-function DSP and high-bandwidth signal processing. He details how Sense uses current transformers (CTs), Rogowski coils, and shunts to capture data, leveraging machine learning for energy disaggregation to identify individual appliance usage from total household consumption. Bamberg discusses the hardware constraints of fitting the Sense device into electrical panels, including compliance with NEC, UL, and FCC standards, and the decision to run a full Linux OS on an i.MX 6 processor for edge processing. The conversation highlights the shift from simple watt-hour measurement to complex signal analysis involving Hilbert filters and FFT, enabling features like safety alerts and utility demand response integration.
