Lutron Caseta vs Leviton Decora Smart (2026) — No-Neutral vs Neutral-Required
Lutron Caseta: works without a neutral wire, requires a hub, most reliable system. Leviton Decora Smart: requires neutral, no hub, simpler setup. Pick by your home's wiring.
If your home was built pre-1985, your switch boxes likely don't have a neutral wire — and that single fact narrows your smart switch options. Lutron Caseta is the no-neutral standard. Leviton Decora Smart is the neutral-required alternative.

The Neutral Wire Problem
Smart switches need constant power to keep their radio alive. AC power requires a complete circuit — hot in, neutral out. Pre-1985 homes wired switches as "switch loops" — only the hot wire passes through the switch box; the neutral lives at the fixture.
Modern code requires neutrals at every switch box, but that doesn't help existing homes. If your home is pre-1985, plan around no-neutral smart switches.
Lutron Caseta Comparison
| Criterion | Lutron Caseta | Leviton Decora Smart |
|---|---|---|
| Neutral wire required | No | Yes |
| Hub required | Yes (Caseta hub) | No (WiFi direct) |
| Radio | ClearConnect (proprietary) | WiFi 2.4 GHz |
| Reliability | Excellent | Good (depends on WiFi) |
| Ecosystem support | HomeKit/Alexa/Google native | HomeKit/Alexa/Google via app |
| Per-switch price | $50-70 | $30-50 |
| Hub price (one-time) | $50-100 | $0 |
| Max devices on hub | 50 | Unlimited (no hub) |
Where Caseta Wins
Reliability — the proprietary ClearConnect radio doesn't compete with your WiFi for bandwidth. Caseta switches respond instantly even when the home network is choppy. The hub-based architecture is more stable than WiFi-direct.
No-neutral capability — the killer feature for older homes.
Where Decora Smart Wins
No hub purchase — saves $50-100 upfront. Direct WiFi connection means simpler setup. Per-switch price is lower.
For homes with neutrals at every switch (post-1985), Leviton Decora Smart is the cheaper path with comparable functionality.

How do I know if I have a neutral wire?
Pull the cover off a switch. If you see a white wire bundled into a wire nut at the back, you have a neutral. If only black wires + ground, no neutral.
Is the hub a problem?
No — Caseta hub is rock-solid. One-time setup, lives in a closet, never touched again.
Can I mix brands?
Lutron and Leviton don't talk directly, but both work with HomeKit/Alexa/Google. Mix at the ecosystem level if needed.
What about Inovelli, Kasa, GE Cync?
All viable. Inovelli is the no-neutral alternative if you don't want a hub. Kasa and GE Cync require neutral.
Pro install — is it worth it?
$79-129 per switch (multi-switch discount). For multiple switches, yes — proper neutral verification and ecosystem setup matter.
