Shelly Pro 3EM (with 3x 120A clamps)

Introducing the Shelly Pro 3EM, the ultimate energy monitoring solution for your home or business. This innovative device comes equipped with three 120A clamps, allowing you to accurately measure the energy consumption of up to three circuits simultaneously.

Next Generation 3-Phase Energy Meter: The DIN-mountable, Wi-Fi-operated Shelly Pro 3EM 3-Phase Energy Meter includes LAN, Bluetooth, and Wi-Fi connectivity. Shelly Pro 3EM has an active energy measuring accuracy of 1% and may be used to track the consumption of individual office equipment, electric circuits, and household appliances. It has 60 days of historical data stored on the device, with a resolution of one minute per phase. Its scripting features also enable more comprehensive monitoring capabilities and enable the execution of intricate sequences.

Industry-grade Security: Shelly Pro 3EM supports mTLS for MQTT, HTTP, and secure outbound WebSockets. Direct connections to your Cloud infrastructure are possible thanks to its industry-grade security, which lowers the expense of setting up complicated networks and VPNs.

Endless Use Applications: Shelly Pro 3EM brings support for MODBUS for voltage, current, power, and energy. You can precisely sample your energy use as well as the voltage, current, and power values in real-time. Custom implementations that can report to your infrastructure as quickly as every 100 ms are possible with our new firmware platform.

2-Way Energy Consumption Monitoring: Keep an eye on your house, workplace, or manufacturing to prevent unexpected costs or voltage dips that could harm your gadgets and appliances. The energy produced and used in each of the three stages can be calculated using Shelly Pro 3EM's two-way consumption function. A mono-phase electrical system's three distinct circuits can be measured using the gadget. Check the voltage, power factor, active power, and reactive power of your electrical network.

Local Control: You may now effortlessly manage other Shelly or Wi-Fi devices on your local network with the help of Shelly Pro 3EM's scripting features and webhooks. Make use of these features to have your gadgets automatically reduce power use by setting precise conditions for heating, cooling, or charging electric vehicles based on photovoltaic production. None of them require the use of a Cloud. 

Solar Panels and Monitoring Control: Easily save money by monitoring the electricity your wind turbines or solar panels are producing. Shelly Pro 3EM offers historical data on the amount of energy created and used per minute for the previous 60 days, in addition to providing real-time information regarding the efficiency of the solar and wind energy systems. By doing this, you can maximize the energy output from your wind turbines and solar panels by controlling the energy flow. To go one step further, set up scenes to cause desired activities, such as turning off appliances or setting off alarms, by connecting Shelly Pro 3EM to your other Shelly devices.
