To connect a Kasa smart plug to Alexa, you first set it up in the Kasa app, then link Kasa to Alexa so the plug shows up as a controllable device. Once linked, you can turn the plug on and off with simple voice commands like “Alexa, turn on the lamp.”

What you need

  • Kasa smart plug (TP-Link Kasa series, like HS105 or similar).
  • A 2.4 GHz Wi‑Fi network (Kasa plugs do not use 5 GHz).
  • Smartphone with:
    • Kasa Smart app installed and logged into your TP-Link/Kasa account.
* Amazon Alexa app installed and logged into your Amazon account.
  • An Alexa‑enabled device (Echo, Echo Dot, Echo Show, or Alexa on your phone).

Step 1: Set up the Kasa plug in its app

  1. Plug the Kasa smart plug into a wall outlet and wait until its LED blinks (setup mode).
  1. Open the Kasa Smart app on your phone.
  2. Tap the “+” or Add Device , then choose Smart Plug and the correct model (e.g., HS105).
  1. Follow the on‑screen steps:
    • Connect your phone to the temporary Kasa Wi‑Fi if prompted.
 * Select your home Wi‑Fi (must be 2.4 GHz) and enter the password.
  1. Wait until the plug shows as online and the LED turns solid (often blue).
  1. Give it a clear name like “Living Room Lamp” or “Coffee Maker” in the Kasa app.

Once this step is done, the plug is on your Wi‑Fi and can already be controlled inside the Kasa app.

Step 2: Link Kasa to Alexa

You can link from either the Alexa app or sometimes directly from Kasa; using Alexa is the most common.

  1. Open the Amazon Alexa app.
  2. Tap Devices (bottom menu), then the “+” icon, then Add Device.
  1. Choose Plug (or Kasa Smart if you see it), then pick Kasa Smart / TP-Link Kasa from the list.
  1. When prompted, tap Enable to Use or Link.
  1. Sign in with the same Kasa/TP-Link account you used in the Kasa app and grant permission so Alexa can access your Kasa devices.
  1. After authorization, Alexa will confirm the Kasa skill/account is linked and start Discovering devices.
  1. Wait for Alexa to finish discovery; your Kasa plug should appear as a new plug under Devices.

If the plug does not appear automatically, you can say:

“Alexa, discover devices.”

or tap Discover Devices in the Alexa app’s Add Device flow.

Step 3: Name and organize the plug in Alexa

Once Alexa finds the plug:

  • In the Alexa app, open Devices → Plugs , tap your new Kasa plug.
  • Rename it to a short, clear name like “Bedroom Lamp” for better voice recognition.
  • Optionally:
    • Add it to a Room/Group (e.g., “Living Room”) so you can say “Alexa, turn off the living room lights.”
* Include it in **Routines** (e.g., at 7:00 AM turn on “Coffee Maker”).

Step 4: Test voice control

Try a few voice commands near your Echo or using the Alexa app:

  • “Alexa, turn on Bedroom Lamp.”
  • “Alexa, turn off Bedroom Lamp.”
  • If grouped: “Alexa, turn off living room.”

If the plug responds correctly, your Kasa smart plug is successfully connected to Alexa.

Quick troubleshooting tips

If something doesn’t work smoothly, these are common fixes:

  • Alexa can’t find the plug
    • Confirm the plug works in the Kasa app first; if not, redo setup in Kasa.
* Make sure both Echo and plug are on the **same home network** and that the plug uses 2.4 GHz Wi‑Fi.

* Disable and re‑enable the **Kasa skill** in the Alexa app, then run **device discovery** again.
  • Plug is offline in Alexa
    • Check that the plug’s LED is on and your Wi‑Fi is stable.
    • Restart the plug by unplugging and plugging it back in.
* Reopen the Kasa app to verify the plug is online, then refresh devices in Alexa.
  • Voice commands not recognized
    • Shorten or simplify the device name (“Lamp” instead of “Cute Fairy Room Lamp”).
* Avoid having multiple devices with nearly identical names (e.g., two different “Lamp” devices).

Mini FAQ and extra context

  • Do I need both apps?
    Yes. The Kasa app handles the plug’s Wi‑Fi setup, while the Alexa app handles voice control and routines.
  • Can I control the Kasa plug when away from home?
    As long as the plug is online and linked, you can control it remotely via Alexa or the Kasa app, and use routines and schedules.
  • Is this still the right method in 2026?
    Recent guides from late 2024–2025 show the same basic flow: set up in Kasa, add the Kasa skill in Alexa, sign in, then discover devices.
