Shelly 3EM 63W Gen 3

The Shelly 3EM 63W Gen 3 is the ultimate energy management solution for three-phase systems or multiple single-phase circuits. Built on the 3rd generation architecture, this device features Class B accuracy and native Matter integration, enabling local control and full interoperability with all major smart home platforms.

This equipment independently measures voltage, current, and power factor for each phase, making it an essential tool for optimizing energy consumption and managing surpluses in photovoltaic systems. Its Wi-Fi and Bluetooth connectivity, combined with the powerful Gen 3 processor, ensures near-instant response times and the ability to run complex automations directly on the device.
