EASY HOME SMARTPLUG
A Wi-Fi-enabled single-phase AC power monitoring and control device, controllable remotely via web app or smart-home integration. Built on the ESP32-C3 with a high-precision single-phase energy-metering IC on the measurement front end, it captures power draw with enough resolution to read the current signature of whatever's plugged in, then uses that signature to detect when a device has gone idle and cut power automatically, killing standby waste.
