Shelly 2L Gen3 Dual Relay for No-Neutral Lighting

Shelly 2L Gen3 controls two lighting circuits where a neutral wire is not available at the switch. It provides two relay outputs, with a maximum switching power of 200 W on output 1 and 700 W on output 2. For LED loads, the included Shelly Bypass for 1L/2L Gen3 is required in parallel with the load on output 1; incandescent loads do not require the bypass. Wi-Fi enables local and remote control, while Bluetooth supports inclusion and gateway functions. Use the Shelly app, web interface, schedules, scenes, scripts, MQTT or webhooks to automate two lights independently. The internal temperature sensor provides overheating protection. This model is intended for 220–240 V AC lighting circuits and fits behind suitable wall switches. Check the bypass wiring and enclosure depth before work. Have a qualified electrician install mains-connected equipment.
