Shelly 1L Gen3 No-Neutral Smart Lighting Relay

Shelly 1L Gen3 adds smart control to one lighting circuit where no neutral wire is present at the switch. The module operates from 220–240 V AC and switches up to 200 W. A Shelly Bypass for 1L/2L Gen3 is included and is required in parallel with LED loads; incandescent lighting can operate without the bypass when its load is suitable. Wi-Fi provides local and remote control, while Bluetooth supports setup and gateway functions. Schedules, scenes, scripts, MQTT and webhooks allow lighting routines based on time, sunrise or other device events. The internal temperature sensor provides overheating protection, and the compact body fits behind compatible wall switches. This is a lighting relay rather than a power-monitoring model, so choose a PM device when energy measurement is required. Confirm load type and bypass placement before work. Have a qualified electrician install mains-connected equipment.
