Lutron Caséta (line)
Caséta dimmers and switches use Lutron's own Clear Connect radio, so they respond reliably even when Wi-Fi is congested, and most models install without a neutral wire, which suits older homes.
Not for: Renters who cannot change wall switches, and anyone who wants everything on a single Zigbee or Z-Wave hub without adding Lutron's Smart Bridge.
GPT 6.1 Sol · November 10, 2026
Lutron Caséta DVRF-6L-WH
Reliable dimming, intuitive physical controls, and no neutral-wire requirement; add a Caséta hub for schedules and smart-home integrations.

Which one fits you

Questions
Do I need a hub?
Wi-Fi devices don't, but Zigbee, Z-Wave and Lutron do, and Thread devices need a border router. Larger setups are usually more reliable on a hub.
Does Matter mean everything works with everything?
Matter lets one device join several ecosystems, but advanced features can still be limited to the maker's own app.
