Shelly 1L Gen3<\/strong> is a compact, Wi-Fi smart relay that offers an ideal solution for upgrading and automating lighting systems where there is no neutral conductor in the wall socket, only a phase conductor. This is particularly useful in older buildings where traditional smart relays are difficult to install. Shelly 1L Gen3 allows remote control of lights, setting schedules and creating automation scenarios without the need for a neutral conductor.<\/p>\n

The device is easy and quick to install, usually taking only about 10 minutes. The Shelly 1L Gen3 is designed to fit behind standard wall switches or in other tight spaces, making it ideal for upgrading existing installations. With built-in Wi-Fi and Bluetooth connectivity, it integrates easily into existing smart home systems, allowing remote access and control.<\/p>\n
