Overview
Many smart switches need a neutral wire that older switch boxes do not have. A smart-home install starts by checking box wiring, choosing a single ecosystem and planning where hubs and Wi-Fi coverage are needed.

Safety first
Turn off the breaker before opening any switch box; smart devices do not change that rule.
Warning signs
If any of these sound familiar, it is time to have a licensed electrician take a look.

Questions
The switch needs constant power for its radio. Some models work without a neutral, but neutral-wired models are generally more reliable.
Manufacturers generally recommend replacing smoke alarms about every 10 years. Check the date on the back.
