Shelly Pro 3em 3-phase current consumption meter incl. 3x current transformers 120a

The Shelly Pro 3em (mpn: 1111) is a precise 3-phase power consumption meter that is easily connected via wifi, 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 readings 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 - produced as well as consumed energy 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 to avoid unnecessary expenses and voltage drops 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. In addition, it shows you the quality of your power grid. Including active power, reactive power, voltage and power factor. So you always have an overview and protect your technology effectively.

Intelligent control for your home

With the scripting functionalities and webhooks of the electricity meter, you can easily control other Shelly or WiFi devices in your local network. Use these functions to define 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 smarter - without any cloud connection. This allows you to reduce costs, save energy and optimize your everyday life effortlessly.

Industrial setup

The Shelly supports MODbUS to accurately measure voltage, current, power and energy consumption. You receive precise measured values and instantaneous values to optimally monitor your energy consumption. Thanks to the firmware platform, you can make individual adjustments and send up-to-date data to your infrastructure every 100ms. This means you always have 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 are generating. It provides you with real-time information about your system, as well as historical data on the 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 grid

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

Full harmony and consistency

Shelly devices are compatible with Alexa, Google Home, Android and ios. So you can control everything simply by voice command. Download the Shelly Smart Control app from the App Store or Google Play.
