Smart switches vs. smart bulbs
Smart bulbs are easy but depend on the wall switch staying on; flip it off and the bulb goes offline. Smart switches and dimmers control whatever fixture is connected and still work like a normal switch, which is why they're often preferred for whole-home setups.
Planning matters: choosing a single platform, confirming which boxes have neutrals, and making sure dimmers are compatible with your LED fixtures. Three-way locations can use smart companion switches instead of rewiring.
What the work typically involves
Pick a platform
Choose a system that works with your phone and voice assistant.

Signs you’d benefit from smart lighting
- Smart bulbs that go offline when switches are flipped
- Old dimmers causing LED flicker
- Too many separate apps and hubs
- Porch lights left on all day
- Switches that are hard to reach
Safety considerations
Line voltage connections: Smart switches connect to line voltage. Installation requires turning off the breaker and correctly identifying line, load, neutral and ground conductors.
What an electrician will check
- Neutral availability in switch boxes
- LED dimmer compatibility
- Three-way and four-way circuits
- Wi-Fi or hub coverage
- Box fill

Frequently asked questions
It depends on the system. Some switches connect directly to Wi-Fi; others use a hub for more reliable mesh networking.
Use a switch designed for fan motors. Standard smart dimmers should not control fan speed.
The physical switch will still work. Remote and voice control may depend on your connection.
