Shelly 3EM-63W Gen3 is the wire version of Shelly’s compact 63 A three-channel energy meter. It can monitor a three-phase supply or three independent single-phase circuits, reporting voltage, current, active and apparent power and accumulated energy for each phase.
The meter supports four-quadrant measurement, Class B active-energy accuracy, photovoltaic monitoring and optional phase-sequence error detection. It stores at least seven days of measurements locally at one-minute resolution and includes Wi-Fi, Bluetooth, a real-time clock, scripting and MQTT support.
