Why Smart home devices in Intro to Computing? - Purpose & Use Cases

The Big Idea

What if your home could take care of itself while you relax?

The Scenario

Imagine you come home after a long day and have to manually turn on every light, adjust the thermostat, and check if the doors are locked--all one by one.

The Problem

This manual approach is slow and tiring. You might forget to turn off a light or leave the door unlocked. It's easy to make mistakes and waste energy or compromise safety.

The Solution

Smart home devices let you control everything from one place, like your phone or voice assistant. They automate tasks and keep your home safe and comfortable without extra effort.
