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

The Shelly 3EM 63T Gen3 Energy Meter (3EM-63T-GEN3) can simultaneously track voltage, current, and both active and apparent power across three phases, while also measuring the total energy consumption of the connected circuit. While it doesn't include a relay and so can't directly control electrical devices, it offers extensive scripting options and integrates seamlessly into a broader Shelly setup. Notifications can be set up and customised to instantly notify users via the free Shelly app once a connected appliances reaches an energy-usage threshold.

Capable of storing up to 60 days of energy data locally, the 3EM 63T Gen3 records usage every 60 seconds and can either store measurements locally in the device for up to seven days, or upload older readings to the cloud. This data is accessible in real time through Shelly’s free mobile app or displayed on a Shelly device such as the Shelly Wall Display.

This is the flat-terminal version of the SHELLY-3EM-63W-GEN3, designed for both single-phase and three-phase installations. Alternatively, the wired model (3EM-63W-GEN3) is also available, which can be wired into appliances rather than being mounted for a range of installation options.
