Why Does My Smart Light Switch Not Work After Installation?

Most smart switches fail after installation due to wiring or compatibility. Common causes include reversed line/load, a missing neutral on models that require one, incorrect 3‑way wiring, incompatible bulbs on dimmers, a tripped breaker, or incomplete Wi‑Fi/app setup. We install and repair smart lighting across Bucks and Montgomery counties.

• Verify breaker is on and power is present.
• Match line, load, neutral, ground to the diagram.
• Check 3‑way travelers and use compatible LED bulbs.
• Finish app pairing and connect to the required Wi‑Fi.
