In this article, I show how to install a Kasa smart wifi light switch.
The process is simple; however, it's possible to make some mistakes during the installation ( I did myself), so I decided to write an article to discuss this topic.
I got this Wi-Fi smart switch on Amazon to install myself in my apartment.
This model is a single pole switch which means it does not work with a second switch on the same room.
The box brings everything necessary for the installation, including the wall mount plate and the electrical wire connectors.

Kasa smart light switch wiring
A regular switch requires 3 wires for the installation.
The Kasa smart switch requires 4 wires for the installation.
The picture below shows the back part of the smart switch with the labels.
As you can see, the white wire is labeled Neutral on the top; then, there are two black wires labeled Live/Load and the green wire labeled as Ground.
The picture below shows a regular switch using three wires.
For the Kasa Smart Switch, you need to use four wires, which means you will use the same wires from your old regular switch plus the Neutral Wire.
See the picture below with the Kasa smart switch wiring diagram.
It's pretty simple; remove the wires from your old regular switch and connect them to the black and green ones (Live/Loads and Ground) and then connect the neutral wire that should be available in the electrical box.
Kasa smart light switch installation example
Here's an example of a real installation.
I removed the old switch from a bathroom to install the Kasa smart light switch.
The first step is to remove the wall plate and the screws from the old switch.
Only two wires were connected to my old switch.
The third one (ground) was not there; perhaps the last electrician just forgot to connect it or was in a hurry. Anyway, the switch was working fine.
I found the ground wire and the neutral inside the electrical box.
The next step was to remove the wires (Live/Load) from the old switch and connect them to the Kasa smart switch. See the details in the picture below.
After wiring everything, I just mounted the smart light switch to the all and turned the breakers on.
As soon as the smart light switch gets power, an LED starts blinking to indicate that it's ready for the setup. The picture below shows the power and Wi-Fi LED.
The final step is to use a smartphone for the Smart Light switch setup and put the wall mount plate back into its place. When everything is finished, the switch shows a round symbol to indicate that it's working.
And the installation it's done. Easy, huh?
You can do it too; just follow this example, and everything will be fine.
