Smart Plug Vs Smart Switch: Ultimate Guide to Smart Home Control
Smart homes are becoming popular in many places. People want to control their lights and devices easily. Two common tools to do this are smart plugs and smart switches. But what is the difference? Which one should you choose? This article will help you understand both.
What is a Smart Plug?

How Does A Smart Plug Work?
Once you plug it in, you connect it to Wi-Fi. Then, you use an app on your phone. You can turn the device on or off. Some plugs work with voice assistants like Alexa or Google Assistant. This means you can say “Turn on the lamp” and it will work.
