Monitor and optimize energy consumption
The Shelly EM Gen3 controller is an advanced tool for smart energy management in your home. By precisely monitoring the power consumption of connected devices, it allows you to identify consumption patterns and optimize the operation of equipment. The device can be easily installed in standard electrical boxes, behind outlets or light switches, making it an ideal solution even for places with limited space. With Shelly EM Gen3, you can significantly reduce your electricity bills while ensuring performance and energy efficiency.
Wi-Fi and Bluetooth connectivity - full control without an additional HUB
The controller supports Wi-Fi and Bluetooth connections, allowing you to quickly and easily integrate it into your home network without the need for additional devices. You can also use it as a Bluetooth gateway, which increases flexibility in managing other devices.
Advanced control features
The Shelly EM Gen3 offers the ability to connect up to two current transformers without the need for additional wiring. With a built-in voltage-free contact, you can control high-power consumption devices such as heaters, heat pumps and hot tubs. What's more, the smart scenes function allows integration with other Shelly devices, which opens the door to creating personalized energy-saving scenarios.
Local data storage and analysis
The controller records data locally in one-minute increments, storing it for up to 10 days without a connection to the cloud. Once synchronized with the cloud, the user can access historical data from the last 365 days. Such functionality allows for detailed analysis of energy consumption over a long period and easy tracking of expenses.
Full support for scripting and future Matter technology
Shelly EM Gen3 fully supports scripting, allowing local control and customization of functions. The device is designed with the future in mind - with double the memory compared to the Plus series and Shelly's advanced chip, it allows you to upgrade to Matter and seamlessly integrate with other devices. In the Shelly Smart Control app, you can create virtual devices, integrating third-party products into a cohesive management system.
