Shelly 3EM

Shelly 3EM is a professional-grade 3-phase energy meter that helps you monitor electricity consumption in real time and gain deeper insight into how energy is used across your home or facility. With three independent channels (up to 120 A each), it can track multiple circuits or appliances at once—ideal for residential, commercial, or industrial applications.

This device not only measures power, voltage, current, and power factor, but also stores up to 365 days of data internally, even without Wi-Fi.
