The Neutral Wire Problem

What It Is:

Many smart switches require a "neutral wire" in the switch box. This wire (usually white) provides the return path for the small amount of power the switch needs to stay connected.

Who Has Neutral Wires:

Homes built after 1980: Usually yes
Homes built before 1980: Often no
Brooklyn pre-war buildings: Rarely

Options Without Neutral:

1. Lutron Caseta: Works without neutral (most popular solution)

2. Inovelli: Some models work without

3. Have neutral installed: Electrician can add ($100-200/switch)

4. Use smart bulbs instead: Avoid the issue
