Shelly Dimmer Gen3 – Smart Wi-Fi Dimmer Module

The Shelly Dimmer Gen3 delivers precise and reliable lighting control thanks to its advanced Shelly chip. Designed for flexibility, it operates with or without a neutral wire and allows effortless brightness adjustment via the mobile app or a physical switch. With features such as smart scheduling and night mode, it adapts lighting levels to suit different moments of the day, improving both comfort and energy efficiency.

Smart Control Without a Hub

Connect the Shelly Dimmer Gen3 directly to your Wi-Fi network for full control without the need for an additional hub. It also supports Bluetooth for quick pairing and can function as a Bluetooth gateway.
