WHY SHELLY PRO 3EM?
State-of-the-art three-phase energy meter
Shelly Pro 3EM is a DIN mount three phase energy meter with Wi-Fi, Bluetooth and LAN connectivity. With an active energy measurement accuracy of 1%, Shelly Pro 3EM can be used to monitor the consumption of any individual home appliance, electrical circuit and office equipment. It has 60 days of historical data on the device with a 1 minute resolution for each phase. In addition, its scripting functionalities allow the execution of complex scenes and provide more extensive monitoring capabilities.

FUNCTIONALITIES

4 quadrant measurement

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

Class B accuracy (active energy)

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

Supports MODBUS

It allows an easy and fast implementation in existing industrial installations.

Wi-Fi, LAN, and Bluetooth connectivity

Simultaneous use of Ethernet and Wi-Fi. Supports MQTT, incoming and outgoing WebSocket, UDP, and mTLS.

feeding control

Monitor single-phase electrical systems with up to 3 points simultaneously. Quick notifications and at least 60 days of 1-minute log storage.

Scripting Features

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

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

Infinite applications of use

USE CASES
Industrial facilities
Shelly Pro 3EM supports MODBUS for voltage, current, power and energies. You can accurately sample your energy usage and instantaneous values of voltage, current, and power. Our new firmware platform allows for a custom implementation that can report as fast as every 100ms to your infrastructure.

USE CASES
Two-way monitoring of energy consumption
Take control of your home, office or factory and avoid additional expenses or voltage drops that can damage your devices and devices. Shelly Pro 3EM can calculate bi-directional consumption: energy produced and used for each of the three phases. The apparatus can be configured to measure three separate circuits of a single phase electrical network. Visualize the quality of your electrical network in terms of active power, reactive power, voltage and power factor.

USE CASES
local control
Thanks to Shelly Pro 3EM's scripting and webhooks capabilities, you can now easily control other Shelly or Wi-Fi devices on your local network. Use these capabilities to set exact EV heating, cooling, or charging parameters based on PV output and have your devices automatically reduce energy use. All this without using the cloud.

USE CASES
Monitoring and control of solar panels
Control how much energy your solar panels or wind turbines generate and save effortlessly. Shelly Pro 3EM provides real-time information on the efficiency of the solar and wind power system, as well as historical data on how much power has been generated and consumed every minute for the last 60 days. This helps you control the flow of energy, getting the most out of your solar panels and wind turbines. To take it a step further, connect the Shelly Pro 3EM to your other Shelly devices and create scenes to trigger desired actions like turning off appliances or sounding alarms.

SMART HOME CONTROL, PERFECTED.
