1 Channel Zigbee Retrofit Dimmer

The Retrofit Dimmer adds smooth wireless brightness control to any existing wall switch without replacing hardware or rewiring. It installs behind the switch plate and enables precise dimming through voice commands, scheduled routines, scene presets, or manual adjustment — all while the original switch continues to function as a physical override. Supporting both trailing and leading edge phase-cut dimming up to 200W, it works with a wide range of dimmable LED fixtures, halogen lamps, and compatible drivers. The dimming curve is smooth and flicker-free when paired with quality dimmable loads. Set warm low levels for evening relaxation, full brightness for task lighting, or let automations shift intensity based on time of day and occupancy. Communicates over Zigbee 3.0 with mesh networking and integrates natively with Home Assistant. Bridges to Matter and Apple HomeKit via a compatible hub. Works seamlessly with Smartify scene switches and touch panels for multi-zone lighting control. Not suitable for non-dimmable fixtures or as a plain on/off relay — use the Retrofit Relay for switching-only applications.
