Smart Lighting Control Made Simple
The Shelly 2L Gen3 is tailored for precise lighting control in homes, apartments, and commercial spaces. With no minimum load requirement when using the included Shelly Bypass, it's compatible with LED, CFL, incandescent, halogen, and luminescent lights. Control your lights locally over Wi-Fi, remotely via the internet, or integrate with cloud-based home automation platforms. Set timers and schedules to turn lights on and off automatically, ensuring you never leave lights on by mistake while saving energy.
Flexible Installation & Compatibility
Designed with adaptability in mind, the Shelly 2L Gen3 fits snugly within standard electrical wall boxes or discreetly behind light switches, even in tight spaces. Output terminal 1 supports loads up to 200 W, while output terminal 2 handles up to 700 W, making it ideal for controlling ceiling lights, accent lighting, or task lights independently. The device operates on 220-240V AC power and consumes less than 1.2 W in standby.
