Why Does My Smart Light Switch Not Work After Installation?
Most smart switches fail after install due to wiring or compatibility issues. A reversed line/load, missing neutral, or using non‑dimmable LEDs with a dimmer can stop it from working. Multi‑way circuits often need a companion switch. A tripped breaker or loose connection can also be the cause. If you’re unsure, cut power at the breaker and schedule an electrical safety check. Wisler services lighting controls and motion/automatic lighting in Roanoke and nearby.
Quick checks:
- Confirm neutral present and connected
- Verify line vs. load placement
- Use compatible bulbs (dimmable if dimmer)
- Restore power and test/reset
