How Do Smart Plugs Work?

Smart plugs convert ordinary devices and appliances in your home into “smart” ones. They do this by allowing you to control the power supply to the appliance through an app on your smartphone.

You can take any ordinary electrical outlet in your home and put a smart plug in it. The physical outlet in your wall stays the same while the appliance or device that’s plugged into the smart plug can now be controlled through your smartphone.

The process to achieve this is simple. The first step is to plug the smart plug into a wall outlet.

The adaptor may seem a little bulky at first, but most smart plugs are neutral in color, so they blend in with the surroundings very well. After a while, you’ll hardly notice the smart plug is there.

Next, download the manufacturer’s app onto your smartphone. Most smart plug apps are available through the Apple App Store or Google Play.

Through the app on your smartphone, you can connect to the smart plug and receive information about its usage.

Now, plug in any appliance or device that you want to control with your smartphone into the smart plug.

And voila! You are now able to turn the appliance on or off using your smartphone.

Some smart plugs allow you to schedule when they will turn on or off. You can program this schedule by the day and by the hour using the smartphone app.

Other smart plugs allow you to monitor energy usage and some can even check the temperature of the wall outlet to make sure it doesn’t overheat.

There are smart plugs available that can be connected to Amazon’s Alexa or Google Assistant. With this option, you can control the smart plug with simple voice commands.

Before purchasing a smart plug, make sure it has all the features you need and can connect with the voice assistant or hub that you may be using.

Smart plugs are made by many different companies and come in many shapes and sizes. They are sold in electronics departments online, in stores, or directly from the manufacturer.

You can buy them individually or in packs of two or more. Some smart plugs are also available as power strips for use with multiple devices.

Do Smart Plugs Need Wi-Fi?

In order for your smart plug to work, you’re going to need a stable Wi-Fi connection. Your smart plug needs to be connected to your smartphone through a Wi-Fi connection so they can communicate with each other.

Without a Wi-Fi connection you won’t be able to control your smart plug with your smartphone, so you’ll have to make sure that there aren’t any disruptions in your service or connection.

Why Use Smart Plugs?

Anytime you want to make your “dumb” appliances and devices “smarter”, you can plug them into a smart plug and enjoy the ease of controlling them from the palm of your hand on your smartphone.
