Smart home basics
Updated
Where to start, whether you need a hub, why devices go offline and how to set up routines that your household will actually use.
The most common beginner mistake is buying devices one by one from different brands and ending up with five apps. Pick your main ecosystem first (Alexa, Google Home, Apple Home, SmartThings or Home Assistant), then buy devices that support it, ideally through Matter.
Start with one problem you want to solve, such as lights you forget or a door you want to check, and make sure everyone at home can still use a normal switch.
