Why I Chose Kasa Smart Switches

Many of us already have Kasa Smart Light Switch HS200P3 here / HS220P3 here.

For those who prefer a HomeKit/Matter enabled switch here, and the Kasa Matter Smart Dimmer here is another great option.

Bringing Kasa Switches into Apple HomeKit

If you’re new to Homebridge, don’t worry—it’s not as complicated as it sounds. I already had Homebridge set up (if you don’t, check out my Homebridge setup guide to get started), so I jumped right into adding the TP-Link plugin to bridge my Kasa switches into HomeKit.

Step 1: Install the TP-Link Plugin for Homebridge

Method 1: Using the Homebridge UI (No Command Line Needed!)

  1. Open Homebridge UI in your browser (usually accessible at http://homebridge.local or your device’s IP address).

  2. Click on Plugins in the navigation menu.

  3. In the search bar, type homebridge-tplink-smarthome.

  4. Click Install on the plugin entry.

  5. Wait for the installation to complete and restart Homebridge when prompted.

Method 2: Using the Command Line

Alternatively, if you prefer the command line, you can install the plugin manually:

sudo npm install -g homebridge-tplink-smarthome

Step 2: Configure the Plugin

Once installed, the plugin needs to be configured.

  1. In Homebridge UI, go to Plugins → Homebridge TP-Link Smarthome → Settings.

  2. Click Add Accessory and follow the on-screen prompts to detect and add your Kasa devices.

  3. Click Save and Restart Homebridge.

Alternatively, if you’re configuring via config.json, add the following:

{
  "platforms": [
    {
      "platform": "TplinkSmarthome",
      "name": "TplinkSmarthome"
    }
  ]
}

Restart Homebridge:

sudo systemctl restart homebridge

Step 3: Add Homebridge to Apple Home

The final step was to add Homebridge to Apple’s Home app:

  1. Open the Home app on my iPhone.

  2. Tap Add Accessory and scan the Homebridge QR code (found in the Homebridge UI).

  3. Boom! My Kasa smart switches appeared in HomeKit!

My Experience with Kasa + Homebridge

Within just a few hours, I had transformed my living room, dining room, and kitchen with a mix of HS220 dimmersand HS200 switches. Now, I can:

  • Control lights with Siri: "Hey Siri, dim the living room lights to 50%."

  • Create automations: My lights turn on at sunset and off at bedtime.

  • Use the Home app: Everything works just like a native HomeKit device!

The best part? No more jumping between apps—everything is in Apple’s Home ecosystem!

Final Thoughts

If you love Apple HomeKit but don’t want to overspend on HomeKit-native devices, Homebridge is a game-changer. With Kasa Smart Switches and Homebridge, you get all the benefits of smart home automation at a fraction of the cost.
