Smart bulbs are a popular entry point to smart home tech, but they come with a major drawback: when someone flips the wall switch, the bulb goes dark and loses its Wi-Fi connection. Smart switches offer a more practical and inclusive solution by replacing the wall switch itself, keeping it wired directly into your home's electrical system. This allows anyone in the household to control the lights using the traditional switch, without needing an app or voice assistant.
Smart switches also handle multi-bulb fixtures more efficiently and tend to be more reliable over time, as they aren't vulnerable to accidental power cuts at the switch.
