Wiring Guide: Understanding Your Home
1-Way Switch (Single Pole)
What it controls: One light from one location
Wiring: Live wire in, switched live out, neutral required for smart switches
Best for: Most rooms, simple setups
2-Way Switch (Two-Way)
What it controls: One light from two locations (e.g., hallway top and bottom)
Wiring: Two switches connected via traveler wires
Smart solution: Install smart switch at main location, compatible companion switch at second location
Multi-Way Switch (3+ Locations)
What it controls: One light from three or more locations
Wiring: Multiple switches with complex traveler wiring
Smart solution: One master smart switch, multiple wireless remote switches
Important: Neutral Wire Requirement
Most smart switches require a neutral wire. Check your electrical box:
Have neutral wire (white): Most smart switches will work
No neutral wire: Look for “no neutral” smart switches (limited options, often dimmer-only)
Safety Note: Always turn off power at breaker before installation. Consult a licensed electrician if unsure.

Frequently Asked Questions
Q: Do smart switches work without internet?
A: WiFi switches need internet for remote control but work locally. Zigbee and Matter switches work completely offline.
Q: Can I install a smart switch myself?
A: If you’re comfortable with basic electrical work and have a neutral wire, yes. Otherwise, hire an electrician.
Q: Will smart switches work with LED bulbs?
A: Most do, but check compatibility. Some dimming switches need a minimum load (bypass capacitor may be needed).
Q: Can I use smart switches in a 2-way setup?
A: Yes, but you need compatible companion switches or wireless remotes.
Q: What’s the difference between smart switches and smart bulbs?
A: Smart switches control the power to any bulb. Smart bulbs replace existing bulbs and offer color control. Smart switches are better for permanent installations.
