Shelly 2L Gen3 dual smart relay, no neutral required
The Shelly 2L Gen3 is the smallest wireless smart home device of its kind in the world. It controls two lighting circuits, or any electrical load up to 200 W on output O1 and up to 700 W on output O2, even without a neutral wire.
Installed behind a wall switch, the Shelly 2L Gen3 turns it into a smart switch you can control remotely and by voice, with a host of advanced smart home features.
To make your lighting smart, simply install the Shelly 2L behind your existing switch (no preparation and no neutral wire needed) and connect it to your Wi-Fi network. That’s it: timers, Shabbat timers, scenes, voice control and more are now at your fingertips.
Note: with bulbs under 20 W, or if the light flickers, connect a bypass in parallel with the bulb. One is included in the box.
Low-quality LED bulbs may flicker.
It is not recommended for lighting circuits with several daisy-chained fixtures.
