Kasa Smart WiFi Light Switch – Installation

I had some fun installing the Kasa Smart WiFi Light Switch; that was after I got over the fact that I had just bought my first smart WiFi Light Switch and now I had to actually install it. I had some fears: Was this worth it? Am I going to destroy my electrical outlet? Will it actually work? Is it hard? Please note that Automate Your Life may receive proceeds from clicking on affiliate links.

Let’s encourage you to do it yourself (DIY) with two points: 1) It’s worth it. 2) No, you most likely will not destroy your current light switch enclosure if you follow the instructions, and it will work. We have to do some checks first before showing you how to install the Kasa Smart Switch.

Kasa Smart Switch Installation Guide

  • (1) Install the Kasa Smart App. You can get the Kasa Smart App from the Google Play Store. The Kasa Smart App will walk through all the steps. So, let’s get started. (2) Open up the App, (3) create a login, then return to the App to Add a Device. (4) touch the ‘plus’ symbol at the top of the screen. (5) Touch: Add a Device. You will see a number of devices that you can install. (6) Touch the Smart Switches option. (7) Select ‘Smart Switch’ HS200′. (8) If you have not installed the device already, press ‘Not Yet’
  • WIFI – You need to make sure that you have sufficient WiFI. In my case, my light switch was behind a wall in a closet (specifically for the Christmas light plug). You should make sure that you 2.4 GHz WiFi has enough juice to connect. Most of the time, it’s not a problem.
  • TURN THE POWER OFF. Check which circuit breaker needs to be turned off to make sure the circuit is dead with a load tester. If you do not have one, Please it’s $15 – $30 to get something that will work.
  • Determine what type of switch you have: Check for the Kasa Smart Switch Wiring setup: You need to check if the light switch is a single-pole device and that it has a neutral wire. Single Pole means that the device is to control one device. It’s not a 3-way controller or it’s not controlled by another switch. Many houses have lights or devices controlled by a number of light switches. Check. If there is more than one switch to control the circuit, STOP. Get the 3-way light switch here. The neutral wire is required for the device to provide current to and back through your circuit. If it’s not hooked up to your light switch, it might be tucked away in the back. Take a look. You may not have a ground wire – it’s ok to not have a ground wire in this case. I did not have one, so this setup will continue without installing a ground wire. Either way, the Kasa App walks you through the steps.
  • Power is off at the circuit breaker. Now you will open up the switch with your trusty flathead tool or screwdriver. Keep your screws. Gently pull the switch out without disconnecting the wires. You will need to look where the wires are connected.
  • Use your voltage detector to test the circuit (the wires connected to the light switch). There should be no confirmation of beeping or lighting from the load/voltage detector. This means the circuit is dead and should be safe to work on.

Neutral wire bundled in the back. Check for this
  • Check for Neutral Wire: The Neutral wire may be bundled in the back of the light switch enclosure. If you do not have this; you need to STOP. If you do have the neutral wire, you can continue with this installation. The Kasa app will ask you if you have the neutral wire. Label the neutral wire. The box was supposed to come with one. Mine did not. You may need to use electrical tape to label it. Don’t use paper.
  • Check for Ground Wire; again, my installation had a ground wire connected to the back of the lightbox. I could not reach it without disassembling the whole light enclosure, so I continued without it.

  • Identify the Live and Load Wires: These wires are generally not labeled on the light switch box. You may have to look at the colors of the wires. One is usually Red, and one usually Black, Or just Black and White. Apply a label of Live or Load to each wire.

  • Take off the decorative wall-plate from the Smart Switch. The Kasa Smart App did not tell you to do this, but the decorative wall-plate in my box surrounding the Smart Switch was already attached. You will need to take this off. Pull off the wall plate gently so you don’t break off the clips. You will need the wall-plate after installing the Smart Switch in the enclosure.
  • Disconnect wires from the old light switch; then Connect the designated wires on the Kasa Smart Light Switch to the labeled wires. Use the provided wire caps and make sure the connections are solid. Give them a tug to make sure the caps have held the wires in place.
  • Installing the Smart Switch: You will have to neatly fold the wires to ensure the Smart Switch can fit into the enclosure. This is probably the most tedious step which can take a few minutes. Be patient. Take your time. You’re almost done!
  • Line up the Smart Switch with the mounting holes. Use the provided screws to secure the Smart Switch to the lighting enclosure. The Smart Switch should now be fastened securely to the wall.
  • Power On: Go back to the electrical panel, and turn on the circuit breaker. The Smart Switch should be blinking Orange and Green. Once done, the Kasa App will then request your WiFi credentials and connect to the Kasa Smart Wi-Fi Light Switch.

Setup the Kasa Smart Wi-Fi Switch with Kasa Smart App

The Kasa Smart App should now connect your device. You will be provided a list of the device with it’s MAC address. In my case, it was the only Kasa Smart Light Switch. The Smart Switch will require a software update. Once that is done you can then see the device in your Kasa Smart App. You can then label your device as ‘Christmas Lights’.

Once this is done you can then login to Alexa, Google Home, Samsung SmartThings, IFTTT, or Microsoft Cortana to integrate into the Smart Home ecosystem of your choice.

I hope that this Setup article for the Kasa Smart WiFi Light Switch was useful for you. You can do it. You can install the Kasa Smart Light Switch and benefit from the power of automation and energy savings. Enjoy.
