FEATURED FEATURES
✅ Smart control without neutral wire
The Shelly 1L Gen3 was developed to intelligently control a lighting load with a maximum power of 200W, in installations that do not have a neutral wire in the switch.
✅ Includes a Shelly Bypass 1L/2L Gen3
Using the Shelly Bypass, included in the package, it also allows you to control low-power LED loads with great reliability, without having to modify the existing wiring.
✅ Wi-Fi and Bluetooth connectivity
Wi-Fi connectivity ensures local and remote control without the need for an additional hub. Bluetooth facilitates initial setup and can act as a gateway for Shelly BLU sensors.
✅ Compatible with Matter and local automations
With support for the new Matter standard (via firmware update), Shelly 1L Gen3 offers greater interoperability with modern home automation platforms. It also supports local scenes, timers and offline control via Wi-Fi.
✅ Security and reliability
Equipped with a temperature sensor to detect overheating, the Shelly 1L Gen3 guarantees safe and reliable operation in residential environments, as long as it is installed correctly and protected by a 10 A circuit breaker (with curve B or C).
