Device overview
Shelly 3EM-63T Gen3 is a compact three-channel energy meter for three-phase systems or three independent single-phase circuits. It is best suited to homeowners and installers who want local Wi-Fi monitoring, Home Assistant compatibility, and photovoltaic-ready import/export visibility without adding a separate hub.
Key fit
The official Shelly sources support 63 A channel context, Class B active-energy accuracy, four-quadrant measurement, Wi-Fi and Bluetooth connectivity, an embedded web interface, and local protocols including MQTT, HTTP, WebSocket, and RPC. Shelly Cloud is useful for remote access, but local monitoring and automation do not depend on it.
Selection notes
This record is scoped strictly as an energy meter. It should not carry inverter, battery-storage, EV-charger, or gateway-only fields. Buyers should confirm regional certification, panel fit, and whether the 63T flat-terminal model is physically suitable before choosing it over the related 63W wire model or larger Shelly Pro meters.
