Cync 4-Wire On/Off Button Style Smart Switch: Makes traditional bulbs smart via app
For anyone wanting smart light control without changing bulbs, the Cync Smart Switch turns your existing fixtures intelligent. Instead of replacing every lamp, install this switch and schedule your porch light for sunset, or set your kitchen to turn on before you wake. It works with Alexa and Google Home for voice commands, and the app lets you adjust lights from anywhere. Just say "Alexa, turn off the living room" and the switch responds instantly. Neutral wire required for newer homes, but DIY installation is straightforward. The motion of flipping the switch feels just like a standard toggle, yet the Bluetooth and Wi-Fi connectivity opens up full smart home control.
