Features
Wi-Fi Operated
Connect Shelly 2L Gen3 to your Wi-Fi network. No HUB required!
Bluetooth
Quick inclusion via Bluetooth or use it as a Bluetooth gateway.
Perfect to retrofit!
Shelly 2L Gen3 is designed for installation in limited spaces, such as wall switches.
No Neutral wire required!
Power and control your lights, or other connected appliances using just a Live wire, with no need to connect a Neutral wire if you don’t want to.
Smart scenes
Set custom scenes by combining Shelly 2L Gen3 with your other Shelly devices.
Smart schedules
Set custom schedules based on your daily agenda or follow the sunrise/sunset and control your lighting accordingly.
Use Cases
Customized lighting
Shelly 2L Gen3 is perfect for spaces where lighting needs differ, such as a living room with both ceiling and accent lights. Users can adjust each light to create the ideal ambiance and even set up automated schedules for a convenient and fully customizable experience.
Perfect to retrofit! No Neutral Wire Needed!
In many homes, where Neutral wires aren’t available, installing smart switches typically requires significant rewiring. With Shelly 2L Gen3, users can easily retrofit their current setup without additional wiring, as the device operates solely on a Live wire. This setup allows homeowners to install the device directly behind their existing light switches to control two separate lights independently.
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.
*Dependent on the extent of Matter’s functionalities support.
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.
Caution
Installation of certain Shelly devices must be done by a qualified electrician or authorised installer.
