Questions tagged [smart-switch]

A smart switch includes electronic circuitry for remote control (beyond simple three-way switch wiring), smartphone or internet-based control, advanced timing capability or other features not found in traditional switches. Smart switches may require more (e.g., neutral) or fewer (e.g., signal 3-way with one wire instead of two) wires than traditional switches.
