Shelly DIMMER GEN3

Product Introduction

The Shelly Dimmer Gen3 is a compact smart lighting controller designed to provide smooth brightness control for dimmable lighting systems. Installed behind wall switches or inside electrical boxes, the device allows users to remotely adjust lighting levels and automate lighting scenes through the Shelly Smart Control platform or compatible smart home systems.

Using built-in Wi-Fi and Bluetooth connectivity, the dimmer connects directly to your home network without requiring a dedicated smart home hub. This allows users to control lighting from anywhere, create automation schedules, and integrate lighting with other smart devices.

The device supports installation with or without a neutral wire, making it ideal for retrofitting existing lighting circuits in homes where neutral wiring may not be available. Its compact design allows easy installation behind traditional switches while maintaining manual control alongside smart automation.
