The Shelly Pro 3EM is a 3-phase energy meter that can be easily mounted on a DIN rail. This smart energy meter measures energy consumption in your home and provides real-time reports on cumulative energy consumption, voltage, current, and power factor per phase. The meter comes with 3 CT clamps, each capable of measuring up to 120A.

The measurement accuracy of the Shelly Pro 3EM is 1%, and the data is stored for a period of 60 days, with a per-minute breakdown for each phase.

The Shelly Pro 3EM can measure both energy consumption and the generation of electricity from solar panels, making it a versatile solution for energy monitoring.

Additionally, the Shelly Pro 3EM is compatible with MODBUS installations and can be physically expanded with the Shelly Add-on, allowing you to measure parameters like humidity or temperature in your technical room.

Although the Shelly Pro 3EM itself cannot switch devices on or off, the measured data can be used as input for scenes, where other Shelly devices automatically turn things on or off based on the measurements.
