## Description

The Shelly 2L Gen3 is a retrofittable smart switch, offering precise control over lighting without needing a neutral wire. The 2L Gen3 can communicate both with other Shelly devices or the free Shelly mobile app over both Bluetooth and WiFi, offering easy and intuitive smart lighting control with an installation time of less than 10 minutes.

Shelly's 2L Gen3 is designed specifically for controlling two separate lighting circuits, supporting two channels simultaneously and without requiring a neutral wire meaning it's compatible with a huge range of smart lighting installations. This smart relay is compact enough to be retrofitted into electrical boxes, supporting appliances of up to 200W on output terminal 1 and up to 700W on output terminal 2. Also included in the box is a Shelly Bypass for 1L/2L; by adding the bypass in parallel to the load on output 1, the 2L doesn't require a minimum load.
Unlike most smart lighting relays, the SHELLY-2L-GEN3 doesn't require a controller, instead being compatible with Bluetooth and standard 2.4GHz WiFi. The 2L Gen3 can either be controlled through the free Shelly app, or can be integrated into scenes and schedules involving multiple Shelly devices; for more advanced control, the 2L Gen3 supports scripting, HTTPS, MQTTS, Inbound and Outbound Web Sockets, and supports KNXnet.
