## Summary description

Xiaomi Yeelight Wireless Smart Dimmer Switch YLT027 is a battery-powered wireless dimmer and remote control for Yeelight smart lighting systems. It provides smooth brightness adjustment and on/off control without wiring, enabling convenient wall-mount or portable use. Compatible with Yeelight ecosystem for scene control, timed actions and simple local operation.

## Long description

The Xiaomi Yeelight Wireless Smart Dimmer Switch YLT027 is a battery-powered, wire-free controller designed to adjust brightness and power for compatible Yeelight smart lighting. Intended for wall mounting or handheld use, the dimmer provides smooth, incremental brightness control and simple on/off switching. It integrates with the Yeelight ecosystem to trigger scenes, set timers and perform local controls without requiring neutral wiring.
Advantages
The compact design combines a tactile dial and push button for precise dimming and immediate power control. Battery operation removes the need for professional electrical installation, while magnetic or adhesive mounting options allow flexible placement. Compatibility with Yeelight devices enables coordinated scene activation, automation and timed actions through the same smart lighting system.
Suitable for
 Homes with Yeelight smart bulbs and fixtures where a wireless wall-mounted dimmer is preferred
 Rooms without neutral wiring or where rewiring is impractical
 Portable use when a handheld dimmer is useful for seating areas, bedside lighting or mood control
 Integration into Yeelight scenes and schedules for coordinated lighting scenarios
When it may not be suitable
This wireless dimmer is designed to control Yeelight smart lights and requires compatible devices or a supporting Yeelight hub or app for full functionality. It does not replace a mains-wired, hardwired dimmer for non-smart fixtures and cannot directly dim conventional non-smart bulbs without a Yeelight-controlled smart module.

 Control type: rotary dimmer with push-button on/off
 Mounting: wall-mountable with adhesive or magnetic holder; also handheld
 Connectivity: wireless pairing with Yeelight compatible devices (via Yeelight protocol or app)

 Compatibility: designed for Yeelight smart lighting ecosystem
How to use
Install a battery according to the product instructions and pair the dimmer with your Yeelight lights or bridge via the Yeelight mobile app. Mount the unit using the supplied holder, adhesive pad or magnetic base, or carry it as a portable controller. Rotate the dial to adjust brightness gradually and press the central button to toggle power. Configure scenes, schedules and automation in the Yeelight app to expand control options and to use timed actions or multi-device scenarios.
What to consider before purchase
 Ensure your lights or fixtures are Yeelight-compatible or controllable through the Yeelight app
 Confirm whether you need local hub/bridge support for your existing setup
 Check placement options and whether adhesive or magnetic mounting suits your surface
 Verify battery type and expected battery life to match your maintenance preferences
Usage recommendations
Place the dimmer near seating or bedside areas for convenient tactile control, and pair it with preset scenes in the Yeelight app for quick mood lighting. Replace batteries before depletion and avoid mounting on moist or highly textured surfaces to maintain secure adhesion.
