Accuracy class B (active energy)

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

MODBUS support

Enables quick and easy use in existing industrial plants.

WLAN, LAN and Bluetooth connectivity

Simultaneous Ethernet and WLAN use. MQTT, incoming and outgoing WebSocket, UDP, mTLS support.

Power grid monitoring

Simultaneous monitoring of single-phase electrical system with up to 3 sockets. Fast notifications and at least 60 days of data storage in one-minute segments.

Scripting functionalities

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

Commercial level security

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

Endless applications

Industrial facilities

Shelly Pro 3EM provides MODBUS support for voltage, current, power and energies. Your energy consumption and instantaneous values of voltage, current and power can be accurately recorded. Our new firmware platform enables a customized implementation that can report to your infrastructure every 100 ms.

Two-way energy consumption monitoring

Monitor your home, office or factory to avoid unnecessary expenses or voltage drops that can damage your household and office appliances. Shelly Pro 3EM can calculate two-way consumption: energy produced as well as energy consumed for each of the three phases. The device can also be configured to measure three separate circuits of a single-phase electrical system. Display the quality of your power grid in terms of active power, reactive power, voltage and power factor.

Local control

Thanks to the scripting functionalities of the Shelly Pro 3EM and the webhooks, you can easily control other Shelly or WLAN devices in your local network. Use these features to set precise parameters for heating, cooling or electric vehicle charging based on your PV generation and automatically disconnect your devices from power consumption. All this works without having to use a cloud.

Monitoring and control of solar panels

Monitor how much energy your solar panels or wind turbines are generating - save effortlessly. Shelly Pro 3EM provides real-time information on the efficiency of your solar and wind energy system as well as historical data on energy generation and consumption over the last 60 days - in one-minute segments. This allows you to control the flow of energy and make the most efficient use of your solar panels and wind turbines. In a further step, you can link Shelly Pro 3EM with your other Shelly devices and create scenarios to trigger desired actions such as switching off household appliances or triggering an alarm.
