Shelly 2L Gen3 Dual-Channel WiFi Smart Switch for No-Neutral Lights

Shelly 2L Gen3 is a two-channel smart lighting relay designed for installations where no neutral conductor is available at the wall switch. The two outputs provide independent lighting control, while Shelly specifies use of the Bypass for 1L/2L in parallel with the load on Output 1 for the documented no-neutral arrangement.
Wi-Fi and Bluetooth connectivity support remote control without a dedicated hub, while schedules, scenes and sunrise or sunset automation can manage each lighting circuit around daily routines. Its compact format is designed for retrofit installation in limited spaces behind existing switches.
