Short description

Shelly 1L Gen3 (the Device) is a compact smart switch tailored for lighting control. A standout feature of this device is that it doesn't require a Neutral wire to operate. However, it needs a Shelly Bypass 1L/2L Gen3 connected in parallel to the load. You can conveniently manage your lighting through a mobile phone, tablet, PC, or home automation system.

The device can function standalone within a local Wi-Fi network or can be integrated with cloud home automation services. As long as the Shelly 1L Gen3 is connected to a Wi-Fi router and the Internet, users can access, control, and monitor it from anywhere.

Designed with adaptability in mind, Shelly 1L Gen3 is engineered to snugly fit within standard electrical wall boxes, be discreetly placed behind light switches, or in other areas where space might be a limiting factor. An added benefit is its embedded Web Interface, which allows users to not only monitor and control their lighting but also to fine-tune the Device settings with ease.

This device is Matter ready, this functionality can be added with firmware update.

Main features

Perfect to retrofit! No need for a neutral wire. You can power and control your light, or other appliances using just a live wire, with no necessity to connect a neutral wire to the device.
Minimum bulb watts. The device requires a Bypass 1L/2L Gen3 to be installed next to the light, however, that allows it to control bulbs greater than 5W.
Wi-Fi Connectivity: Shelly 1L Gen3 connects to your home Wi-Fi network, allowing you to control it remotely through the Shelly mobile app or other smart home platforms.
Remote Control: You can remotely control the connected device or appliance from anywhere with an internet connection using the Shelly app on your smartphone or tablet.
