Why Does My Smart Light Switch Not Work After Installation?
Most smart switches stop working after installation due to wiring, power, or compatibility issues. Typical causes include no neutral in the box, line/load reversed, an incorrect 3‑way setup, incompatible bulbs or dimmers, a tripped breaker, or incomplete app/Wi‑Fi setup. Our licensed electricians can diagnose the circuit, correct wiring, and verify code compliance in Denver‑area homes.
Quick checks:
- Confirm the breaker is on and power is present.
- Check for a neutral wire; many smart switches require it.
- Match line/load/traveler to the wiring diagram.
- Use dimmable LEDs with dimmer models.
- Complete app pairing and Wi‑Fi setup.
