Auto-Transmitting Feature: For remote dimming, one controller can relay signals to another controller within 30 meters, enabling virtually unlimited control distance when multiple units are installed. all controllers belong to the same group so the remote can manage every connected LED strip seamlessly. Multi-Function Dimming: Adjust brightness smoothly for single-color LED strips and bulbs, create groups and multi-zone control, set and countdown on/off, use biorhythm, Tap-to-Run, automation and custom scenes. Plan sleep and wake-up lighting, enable do-not-disturb mode and share devices with family members. Auto-Synchronization Function: Multiple controllers stay synchronized even when started at different times. When operated by the same remote with identical dynamic mode and speed, all connected monochrome LED strips respond uniformly, delivering consistent lighting effects and avoiding brightness or timing mismatches.
