Every Gen3 device is designed to be upgradeable to Matter. The doubled memory compared to the Plus series ensures a smooth upgrade process and paves the way for new smart features and integrations.
*Dependent on the scope of support for Matter features.

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 significantly improved. This substantial memory increase not only guarantees smoother and faster operation, but also equips the Gen3 series for the introduction of new features.

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.
