SHELLY - 3-phase DIN Smart Energy Meter Shelly Pro 3EM

Shelly Pro 3EM is a Wi-Fi-operated DIN-mountable 3-Phase Energy Meter with Wi-Fi, Bluetooth, and LAN connectivity. With active energy measurement accuracy of 1%, Shelly Pro 3EM can be used to monitor the consumption of any home appliances, electric circuits, and office equipment individually. It features 60 days of on-device historical data with a 1-minute resolution for each phase. Additionally, its scripting functionalities allow for the execution of complex scenes and provide broader monitoring abilities.

4-quadrant measurement

Measure capacitive and inductive load types of active imported and exported energies. 

Accuracy class B (active energy)

Shelly Pro 3EM has a measurement accuracy of  1%.

MODBUS support

Allows for easy and fast deployment in existing industrial installations. 

Wi-Fi, LAN, and Bluetooth connectivity

Simultaneous Ethernet and Wi-Fi usage. MQTT, inbound and outbound WebSocket, UDP, mTLS support.

Power monitoring

Monitors mono-phase electrical systems with up to 3 points simultaneously. Fast notifications and at least 60 days of 1-minute records storage.

Scripting functionalities

Shelly Pro 3PM fully supports mjS scripting, allowing you to create further features and functionalities.

Industry-grade security

Shelly Pro 3EM supports mTLS for MQTT, HTTP, and secure outbound WebSockets. Its industry-grade security allows for direct connections to your cloud infrastructure, reducing the cost of deploying complex networks and VPNs.

2-way energy consumption monitoring

Monitor your home, office, or factory, and avoid additional expenses or drops in voltage that can damage your appliances and devices. Shelly Pro 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate circuits of a mono-phase electrical system. View the quality of your electricity network regarding active power, reactive power, voltage, and power factor.
