## Long description

WiFi Energy Meter and Contactor Control Shelly EM is a compact device for monitoring and controlling electrical consumption in homes, offices and small commercial installations. It provides dual-point power metering for two circuits (up to 120 A each), integrated relay output for contactor control and features such as overconsumption protection, weekly and sunrise/sunset schedules. The unit supports measurement of generated energy from solar panels and offers an embedded web server for direct control without an external hub.
Advantages
Shelly EM measures and controls up to 2x120A, enabling simultaneous monitoring of two separate circuits or inputs such as general home consumption and solar generation. The built-in relay output (2 A / 230 V, 50/60 Hz) is designed to drive a contactor for switching high-current circuits. The device includes protection functions that can automatically cut power when energy or consumption limits are reached, and scheduling options including weekly programs and sunrise/sunset-based actions. An embedded web interface allows device control without additional controllers.
Suitable for
Monitoring overall household consumption
Measuring energy production from solar panels
Controlling circuits via contactor for heating, lighting or power lines
Protecting circuits with overconsumption or pre-paid energy limits
Scheduling devices with weekly or sunrise/sunset timers

How to use
Install the Shelly EM in the electrical panel and connect the split-core current transformers around the conductors you want to monitor (choose 50 A or 120 A CTs according to the circuit). Wire the integrated relay to a contactor coil if you need automatic switching of a high-current circuit. Configure the device using its embedded web server over WiFi to set measurement points, thresholds for overconsumption protection, weekly schedules or sunrise/sunset timers. Use the web interface to view real-time consumption data and to control the relay directly.
Usage recommendations
For safe installation, mount and connect the Shelly EM inside a distribution board by a qualified electrician. Choose CTs with appropriate rating for your circuits, and test overconsumption limits and scheduling settings under supervision before relying on automatic shutdowns for critical loads.
