The Caseta Wireless Smart Fan Speed Control Switch gives you the ability to turn your fan on/off or choose between four speeds for increased comfort. This fan speed control is rated for 1 ceiling paddle fan up to 1.5A. Ceiling fans with integrated fan speed and/or light modules, proprietary remotes, or DC motors are not compatible with this device. Use with the wireless Fan Pico remote (PJ2-3BRL-GXX-F01, sold separately) for control from anywhere around your home. Existing hardwired 3-way switches will not work with this dimmer, for 3-way and multi-location applications Pico remotes must be used with this fan speed control. Replace the existing switch with a Fan Pico remote control and wall plate adapter to control the fan from every location (PICO-WBX-ADAPT sold separately). For increased versatility, add the Caseta Smart Hub (L-BDG2-WH, sold separately) and use with the free Lutron app to set up your favorite scenes and create schedules based on time of day. Integrate with other Smart Home brands, including Amazon Alexa, Google Home, Ring and more. Pairs perfectly with Lutron Claro wall plates for consistent color matching (sold separately).
