Shelly EM Gen3 50A

Monitor The Real-Time Power Usage Of Your Connected Devices

Immediately know the power consumption of your connected devices with the Shelly EM Gen3 50A. This smart energy meter installs behind a wall outlet/switch and can use up to two current transformers for contact-free metering (only one 50A CT is included). When connected to a device it will monitor the energy usage and send the data directly to a mobile phone, tablet, PC, or home automation system. With Wi-Fi connectivity, this energy meter can be controlled, accessed, and monitored remotely from anywhere an Internet connection is available. Plus, it can work as a standalone device in a local Wi-Fi network or via cloud automation services. The included 50A current transformer enables contact-free monitoring, making it ideal for tracking individual circuits, appliances, or energy generation sources.

The Shelly EM Gen3 50A has a small form factor and features a dry contact relay for contactor control, single-phase two-channel energy measurement via current transformers, and internal storage for data logging of up to 10 days at 1-minute intervals. The dry contact output can be used to control external contactors for various load types, including resistive loads (incandescent bulbs and heating devices), capacitive loads (LED light drivers, capacitor banks, electronic equipment, motor start capacitors), and inductive loads (transformers, fans, refrigerators, air-conditioners). Ideal for smart homes, light commercial environments, and energy management applications, the Shelly EM Gen3 50A provides accurate energy monitoring to help make informed decisions that reduce energy consumption and improve overall efficiency.

Shelly Smart Control App – Everything at Home Connected

Enjoy enhanced home automation control and precise monitoring of your Shelly devices no matter where you are with the Shelly Smart Control app. The app connects to Shelly's cloud service to help you control your connected devices remotely and send notifications for all automated events in your home directly to your smart device. You can easily configure devices and manage their settings individually, or you can create personalized scenes by combining Shelly devices to trigger certain actions in your home automation. The Shelly Smart Control App supports real-time power metering with power management (PM) devices, smart plugs, and smart bulbs in order to allow you to build complex automation solutions for improved energy efficiency and lower electricity bills.

• Easy Inclusion and Control: Include and name new devices in the Shelly Smart Control app, assign them to the rooms they are located in, and group them into scheduled or automated scenes.
• Custom Dashboard: Create multiple dashboards for quick access to your preferred devices, rooms, and scenes. Issue commands using your dashboards or your preferred voice assistant towards individual devices or a group of devices.
• Smart Scenes: Combine multiple devices into one smart scene with pre-set triggered actions. Lower the lights when the TV is turned on for a "Movie night". Cut off the power and send a notification when a space heater has been left on past 9am while you are "Away at Work".
• Custom Schedules and Timers: Teach your home how to make you more comfortable by setting custom schedules based on your agenda. You can set a Shelly controlled switch to turn on the outdoor lights at 7:00 PM on workdays, or turn on your heater an hour before you return from work.
• Energy Monitoring: An energy consumption panel gives you a detailed view of your live and recorded energy usage from devices controlled by Shelly Qubino products. The information is stored in a free cloud and fully accessible to you for further analysis of your energy consumption habits.
• Works with Alexa: The Shelly Smart Control app is natively compatible with Amazon Alexa.
