Shelly Dimmer Gen4 Smart Trailing-Edge Light Dimmer

Shelly Dimmer Gen4 provides single-channel trailing-edge control for compatible dimmable lighting. It works with or without a neutral wire and supports dimmable LED lamps up to 150 W, plus incandescent and halogen loads up to 200 W. When used without neutral and the load is under 20 W, a Shelly Bypass for Dimmer is required. Wi-Fi, Bluetooth 5.0 and Zigbee are available; Matter is the default profile and Zigbee can be selected during setup. Use the Shelly app, local web interface, schedules, scenes, scripts or integrations to set brightness and transition behaviour. The module includes an internal temperature sensor and protection functions for suitable installations. Its in-wall form factor fits behind compatible switches, subject to box depth and wiring space. Confirm that the lamp and driver support trailing-edge dimming. Have a qualified electrician install mains-connected equipment.
