Shelly 3EM-63W-GEN3 Single or Three-Phase Energy Meter

Shelly's 3EM 63W Gen3 Energy Meter (3EM-63W-GEN3) is able to monitor the voltage, current, and both active and apparent power across three phases simultaneously, as well as the total consumed energy of the circuit in which it's installed. Although it doesn't contain a relay and so can't directly control electrical appliances, the 3EM 63W Gen3 does support a variety of scripting options and integrates seamlessly into a wider Shelly installation, meaning it can play a vital role in energy conservation by communicating with other Shelly devices to turn off appliances once they reach a certain usage threshold. Notifications can also be set up to instantly feed through to your Shelly mobile app when a device reaches a pre-determined limit of power use.

The 3EM 63 Gen3 is capable of locally storing up to 60 days of energy usage data, recorded in sixty second intervals around the clock, and can automatically upload these metrics to the cloud to securely store older measurements. This data is then displayed on Shelly's free mobile app in real time, or on a physical Shelly display such as the Shelly Wall Display.

This is the wired version of the SHELLY-3EM-63W-GEN3 that can be wired into either single-phase or three-phase installations; alternatively, also on offer is a flat-terminal version (SHELLY-3EM-63T-GEN3) that can be mounted directly onto devices to measure their power usage.
