Features of the Gen3 series

On the path to Matter
Every Gen3 device is designed to be upgradable to Matter. The doubled memory compared to the Plus series ensures a smooth update process and paves the way for new smart features and integrations.
*Depending on the extent of Matter feature support.

More memory, more performance
The Gen3 series ensures the quality and reliability of our devices through the use of our powerful Shelly chip. With an impressive 8 MB of memory, the device's performance and efficiency are greatly improved. This significant memory increase not only guarantees smoother and faster operation but also equips the Gen3 series for the introduction of new features.

Unified control with virtual components
The Gen3 series introduces "virtual components" that transform the management and control of third-party devices. Within the Shelly Smart Control App, you can now create virtual devices to integrate non-Shelly products into a unified control system. This feature enables efficient control of all your smart devices, regardless of brand, through a single user interface.
