💡 What is a trailing-edge dimmer and how does it improve LED lighting in smart-home setups?

- Trailing-edge dimmers use a MOSFET to trim the AC waveform at the end of each half-cycle, delivering smoother dimming with less flicker on LED loads.
- They require a stable 2.4G WiFi connection and a neutral wire for reliable operation and accurate brightness control.
- When paired with Alexa/Google Home via the SmartLife app, you can schedule, create scenes, and voice-control lighting.
- Handy for multi-room lighting and energy-efficient dimming across LED fixtures.
