Most smart switches fail after installation because of wiring or compatibility issues. Lack of a neutral wire, reversed line/load, using a 3‑way circuit without the right model, or incompatible LED bulbs are common causes in Roanoke and Christiansburg homes. Check that the breaker is on and the switch has power; app pairing does not affect basic on/off.
Quick checks:
- Confirm neutral present and connected.
- Verify line vs. load on correct terminals.
- Use bulbs the switch supports (LED/VA rating).
- For 3‑way, use the matching companion switch.
- Power-cycle and reset per manual. Work with power off.
