The Shelly 3EM-63W Gen3 is a compact Wi-Fi three-phase energy meter with integrated current transformers, designed to monitor power consumption across three-phase systems or up to three independent single-phase circuits.
It provides detailed real-time and historical energy data, including voltage, current, active power, apparent power, power factor, and accumulated energy per phase. With local processing, cloud connectivity, and advanced scripting capabilities, it is suitable for home energy monitoring, commercial installations, and energy optimisation setups.
The device includes built-in data storage, an embedded web interface, and Bluetooth onboarding, enabling fast setup and full local operation without requiring a hub.
