Description
The Shelly Pro 3EM is a precise 3-phase power consumption meter that is easily connected via WLAN, LAN or Bluetooth. With an impressive measurement accuracy of 1%, it monitors the energy consumption of all your household and work devices individually, giving you comprehensive control and optimization. It stores this data for up to 60 days, providing detailed measurements every minute. In contrast to the Shelly 3EM, it has Pro an intelligent scripting function, has advanced data and control functions and an improved firmware platform. Furthermore, the electricity meter can calculate the energy flow in both directions - produced and consumed energy for each of the 3 phases. It also shows you the quality of your power network by providing values for active power, reactive power, voltage and power factor.

Two-way energy consumption monitoring
The Pro 3EM helps you avoid unnecessary expenses and brownouts that could damage your devices. It calculates both the energy produced and consumed for each of the three phases and can monitor three separate circuits in a single-phase system. It also shows you the quality of your power network. Including active power, reactive power, voltage and power factor. This way you always have an overview and protect your technology effectively.
Intelligent control for your home
With the electricity meter's scripting functionalities and webhooks, you can easily control other Shelly or WiFi devices on your local network. Use these functions to set precise settings for heating, cooling or charging your electric car based on your PV generation. Your devices are automatically separated from power consumption and managed more smartly - without a cloud connection. This way you can reduce costs, save energy and optimize your everyday life effortlessly.
Industrial facility
The Shelly supports MODBUS for accurate measurement of voltage, current, power and energy consumption. You receive precise measurements and instantaneous values to optimally monitor your energy consumption. Thanks to the firmware platform, you can make individual adjustments and send current data to your infrastructure every 100ms. This way you can always keep an overview and benefit from smart energy control.
Solar panels and your system at a glance
With the electricity meter you can easily track how much energy your solar panels generate. It provides you with real-time information about your system, as well as historical data on energy generated and consumed. This way you can keep an eye on the energy flow and maximize the performance of your PV system.
First-class security for your smart energy network
The Shelly offers security through mTLS for MQTT, HTTP and secure WebSockets. This means you can connect directly and securely to your cloud infrastructure without having to set up expensive and complex networks or VPNs. This means your energy network will not only become smarter, but also safer and more cost-efficient.
Complete harmony and agreement
Shelly devices are compatible with Alexa, Google Home, Android and IOS. This means you can easily control everything using your voice command. To do this, download the Shelly Smart Control app from the App Store or Google Play.
