Shelly Pro 3EM-120 Energy Meter V2 120A 3-Phase Energy Meter

Shelly Pro 3EM-120 Energy Meter V2 120A 3-Phase Energy Meter

The Shelly Pro 3EM V2 is a smart energy meter for your utility closet that gives you a complete overview of your energy consumption and feed-in. It’s ideal for homes with a 3-phase connection, solar panels, a charging station, a heat pump, or other major energy consumers. By accurately measuring consumption per phase, you can see exactly where energy is being used and where you can save.

Smart Energy Management with Accurate Measurements

The Shelly Pro 3EM V2 measures energy consumption, voltage, current, and power for each individual phase. This gives you a complete overview of your electrical system. It also provides insight into energy fed back into the grid—such as from solar panels—allowing you to better manage your own energy consumption.

Connectivity and Smart Home Compatibility

Thanks to support for Wi-Fi, LAN, and Bluetooth, the Shelly Pro 3EM V2 integrates easily into virtually any smart home system. The wired LAN connection ensures a stable connection in the utility closet, while Wi-Fi and Bluetooth offer additional flexibility during installation and use.

The energy meter operates independently via the Shelly Smart Control app and the built-in web interface, without requiring a separate hub. In addition, the meter can be integrated with systems such as Home Assistant and Homey Pro. Thanks to support for MQTT, HTTP, WebSocket, and Modbus, the Pro 3EM V2 is also suitable for advanced automation.

Revamped V2 generation with future-oriented capabilities

The Shelly Pro 3EM V2 builds on the popular Pro 3EM series and combines reliable energy monitoring with modern smart home features. The updated version is ready for future developments such as Matter and provides a solid foundation for local control, integrations, and smart automations.

Automation Based on Energy Consumption

With the Shelly Pro 3EM V2, you can create smart scenarios based on real-time energy readings. For example, you can set it to send a notification when power consumption exceeds a certain threshold, use available solar power more efficiently, or gain insight into the usage of large appliances such as a charging station or heat pump.

The Pro 3EM V2 itself does not have a switchable relay. If you want to automatically control devices based on the measurement data, you can combine it with other Shelly modules or compatible add-ons.

Easy integration into the meter cabinet

The Shelly Pro 3EM V2 is neatly mounted on a DIN rail in the meter cabinet. The included current transformers are easily placed around the phase wires to measure energy consumption per phase.

After installation, add the meter to the Shelly Smart Control app, the local web interface, or your favorite smart home platform. You can then easily view real-time usage, historical data, and detailed energy statistics.
