Whether you're looking to automate your home lighting or simply add convenient remote control capabilities, this dimmer module delivers professional-grade features in a compact form factor that fits seamlessly behind standard wall switches.
Product Overview and Key Features
The Shelly Dimmer Gen4 is engineered to transform ordinary lights into intelligent, remotely controlled lighting systems. This smart home device supports three major wireless protocols simultaneously, ensuring compatibility with virtually any modern smart home ecosystem. The module handles a wide range of lighting types, including dimmable LED bulbs, incandescent bulbs up to 150 watts, and halogen lamps up to 200 watts.
