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, from a single user interface.
