About Lutron
Lutron invented the dimmer switch in 1961 and has spent six decades perfecting the craft. Their Caséta line is the most recommended smart switch series among electricians, smart home installers, and enthusiasts who've been burned by cheaper options. When reliability is the non-negotiable requirement, Lutron is the answer almost everyone converges on.
The secret behind Caséta's legendary reliability is its proprietary ClearConnect RF protocol. Unlike Wi-Fi or Zigbee which share crowded frequency bands, ClearConnect operates on a dedicated 434MHz signal engineered for one purpose: controlling lights. It penetrates walls, works at 100-foot range, and almost never drops connections. The trade-off is lock-in — you need the Lutron Smart Bridge — but for most users, the hub pays for itself in peace of mind.
Lutron's ecosystem compatibility is excellent. Caséta works natively with Alexa, Google Home, Apple Home, SmartThings, and Home Assistant. Home Assistant documents both the L-BDG2-WH and L-BDGPRO2-WH; check supported entities and events for your exact devices. If you're outfitting a whole home and reliability matters more than anything else, Lutron Caséta is the professional's choice.
