Overview
Shelly 3EM-63T Gen3 is a compact Wi-Fi-operated three-phase energy meter designed for monitoring three-phase electrical systems or up to three independent single-phase circuits. This terminal-based version is intended for installations where fixed wiring via screw terminals is preferred.
It delivers precise real-time and historical measurements of voltage, current, active and apparent power, power factor, and accumulated energy per phase. The device supports local operation, cloud integration, and advanced automation, making it suitable for both residential and professional energy monitoring.
With built-in data storage, an embedded web interface, Bluetooth onboarding, and future-ready solar monitoring support, Shelly 3EM-63T Gen3 provides reliable and flexible energy monitoring and optimisation.
