PEACE OF MIND: Set lights to automatically adjust with seasons so your family always comes back to a well-lit home; enable smart away to randomly turn your lights on/off to look like you’re home even if you’re away (Caseta Smart Hub, L-BDG2-WH, required)
MOST CONNECTED: Caseta connects with more leading smart home devices – including Alexa, Apple Home, the Google Assistant, Ring, Serena shades and Sonos – than any other smart lighting control brand (Caseta Smart Hub required)
CONTROL YOUR WAY: Caseta puts the smarts in the switch so you can control your lights a variety of ways – via the free Lutron app, with your voice, or from the wall. Create schedules in the app or activate scenes with a button (Caseta Smart Hub required)
GET MORE, SPEND LESS: One Caseta smart switch can control many bulbs at once; make many bulbs smart, even your existing bulbs. Get smart control of multiple styles of dimmable LED, incandescent, and halogen bulbs
WORKS IN ANY HOME: Unlike other smart dimmer switches, Caseta works in any home, of any age, as it does not require a neutral wire
WIRELESS REMOTE CONTROL: For added convenience, use with wireless Pico remote (PJ2-3BRL-GXX-L01) to turn your lights on, off, or dim and brighten with the touch of a button from anywhere in the home
EASY 3-WAY SETUP: Create a 3-way by mounting Pico to almost any wall surface – no cutting holes or pulling wire, with a wall mount bracket (PICO-WBX-ADAPT sold separately). Replace existing 3-way switches by mounting the bracket and Pico over the backbox
TECHNICAL DETAILS: Works with up to 150W dimmable LED light bulbs/CFL light bulbs or 600W incandescent bulbs/halogen bulbs; not rated for low voltage applications (i. e. track or landscape lighting)
