Features:

• 4-quadrant measurement - For measuring the capacitive and inductive loads of imported and exported active energy.
  
• Accuracy class B (active energy). The Shelly Pro 3EM has a measurement accuracy of 1%.
• MODBUS support - Enables simple and fast implementation in existing industrial installations.
  
• Wi-Fi, LAN, and Bluetooth connectivity - Simultaneous Ethernet and Wi-Fi use. MQTT, incoming and outgoing WebSockets, UDP, and mTLS support.
  
• Monitoring the electricity grid
• Monitors single-phase electrical systems with up to three points simultaneously.
• Fast notifications and at least 60 days of storage of one-minute recordings.
  
• Scripting Features - Shelly Pro 3PM fully supports mjS scripting, allowing you to create additional features and functionality.
  

The Shelly Pro 3EM-400 supports mTLS for MQTT, HTTP, and secure outbound web sockets. Commercial-grade security enables direct connections to your cloud infrastructure and reduces the cost of deploying complex networks and VPNs.

Usage examples:

• Industrial Facilities - Shelly Pro 3EM offers MODBUS support for voltage, current, power, and energy. Your energy consumption and instantaneous voltage, current, and power values ​​are accurately recorded. Our new firmware platform enables a custom implementation that can report to your infrastructure every 100 ms.
  
• Two-phase power monitoring - Monitor your home, office, or factory to prevent unnecessary costs or voltage drops that can damage your home and office equipment. The Shelly Pro 3EM can calculate two-phase power consumption: the energy produced and consumed on each of the three phases. The device can also be configured to measure three separate circuits of a single-phase electrical system. It displays the quality of your electrical network in terms of active power, reactive power, voltage, and power factor.
  
• Local Control - Thanks to the Shelly Pro 3EM's scripting capabilities and webhooks, you can easily control other Shelly or Wi-Fi devices on your local network. Use these features to set precise parameters for heating, cooling, or EV charging based on your PV generation, and automatically disconnect your devices from power consumption. All of this works without the need for a cloud.
  
• Solar panel monitoring and control - See how much energy your solar panels or wind turbines are generating and 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 energy consumption from the past 60 days—in one-minute increments. This allows you to control the energy flow and use your solar panels and wind turbines as efficiently as possible. Next, you can connect Shelly Pro 3EM to your other Shelly devices and create scenarios to perform desired actions, such as switching off appliances or activating an alarm.

Support:

• Full compatibility – Shelly devices are compatible with Alexa, Google Home, Android, and iOS. Together with their voice assistants, they can support their Shelly devices!
  
• Shelly Smart Control – An app for room control, energy management, and energy savings. Configure your dashboards, receive detailed consumption reports, and track your energy bill.
