The CYNC Smart Keypad Dimmer Light Switch puts scenes and groups at your fingertips. In addition to enabling out-of-home control, scheduling and scene-setting of your lights, the switch features customizable buttons. Use the smart WiFi switch to create unique lighting scenes for morning and evening or group with other Cync smart lights and control an entire room with one touch. The smooth dimming works with traditional dimmable LED and incandescent bulbs. Install CYNC smart bulbs on the same circuit to keep schedules and voice control available even when the switch is turned off. Pair with CYNC smart bulbs in other fixtures and control all your lights from one wall switch. Designed for single-pole, 3-way or 4-way circuits, one CYNC Smart Paddle Dimmer Switch makes an entire multi-way circuit smart—no additional smart switches required. Create multi-way connections using the included traveler wire and traditional switches or virtual 3-way connections using multiple CYNC Smart Switches, including switches on different circuits. Includes a décor wall plate and fits inside traditional wall plates when installing with other switches. Install CYNC Smart Switches on your own with easy, DIY setup or with the help of a professional in newer homes built after 1980 using 2.4GHz WiFi. With Matter compatibility, connect to Amazon Alexa, Google Assistant, Apple HomeKit and Samsung SmartThings apps—no hub needed. Neutral wire--usually a white or gray wire--is required.
