Shelly Pro 3EM 3-phase power consumption meter incl. 3x current transformers 120A

The Shelly Pro 3EM (MPN: 1111) is a precise 3-phase power consumption meter that can be easily connected via Wi-Fi, LAN, or Bluetooth. With an impressive measurement accuracy of 1%, it monitors the energy consumption of all your household and work appliances individually, giving you comprehensive control and optimization. It stores this data for up to 60 days, providing detailed measurements every minute. Unlike the Shelly 3EM, the Pro has an intelligent scripting function, advanced data and control functions, and an improved firmware platform. Furthermore, the electricity meter can calculate the energy flow in both directions—energy produced and consumed for each of the 3 phases. It also shows you the quality of your power grid 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 voltage drops that could damage your equipment. 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 grid, including active power, reactive power, voltage, and power factor. This gives you a constant overview and effectively protects your technology.

Smart control for your home

With the scripting capabilities and webhooks of the electricity meter, you can easily control other Shelly or Wi-Fi devices in 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 disconnected from power consumption and managed more intelligently—without any cloud connection. This allows you to reduce costs, save energy, and optimize your everyday life with minimal effort.

Industrial setup

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 100 ms. This allows you to maintain an overview at all times and benefit from smart energy management.

Solar panels and your system at a glance

With the electricity meter, you can easily track how much energy your solar modules generate. It provides you with real-time information about your system, as well as historical data on energy generated and consumed. This allows you to keep an eye on the energy flow at all times and maximize the performance of your PV system.

First-class security for your smart energy network

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 not only makes your energy network smarter, but also more secure and cost-efficient.

Full harmony and compatibility

Shelly devices are compatible with Alexa, Google Home, Android, and iOS. This allows you to control everything easily with voice commands. Download the Shelly Smart Control app from the App Store or Google Play.
