Why Does My Smart Light Switch Not Work After Installation?
Most smart switches fail after install due to wiring or network issues. Common causes include no neutral in the box, line/load reversed, incompatible 3‑way wiring, or 2.4 GHz Wi‑Fi setup errors. Bulb incompatibility and a tripped breaker or GFCI/AFCI can also stop power. We handle smart controls across Springfield and Nixa homes.
Quick checks:
- Confirm power at the breaker and reset GFCI/AFCI.
- Verify line vs load and neutral connections per the switch diagram.
- For 3‑way, use the correct traveler and supported model.
- Pair on 2.4 GHz Wi‑Fi; update firmware/app.
