Gen3 Series features

On the Road to Matter

Each Gen3 device is engineered to be upgradable to Matter. The doubled memory, compared to Plus series, guarantees a smooth update process, paving the way for new smart capabilities and integrations.  

More Memory, More Power

The Gen3 series ensures the quality and reliability of our devices by using our own powerful Shelly chip. Boasting 8MB of memory, this dramatically improves device performance and efficiency. This significant increase in memory not only guarantees smoother and faster operation but also equips the Gen3 series for the introduction of new capabilities. 

Unified Control with Virtual Components

The Gen3 Series introduces “virtual components, transforming how you manage and control 3rd party devices. Within the Shelly Smart Control app, you can now create virtual devices, integrating non-Shelly products into a unified control system. This feature provides streamlined control of all your smart devices, regardless of brand, from a single interface.
