Why is my Kasa Light Unresponsive to Alexa?

Your Kasa Light is most likely unresponsive to Alexa due to a connectivity issue. Other possibilities are Kasa app malfunctions, issues with the Alexa device or app, or physical interferences between the light and Alexa device.

Connectivity issues can happen due to Wi-Fi network discrepancies, weak Wi-Fi signals, or router overload, and if your connection is fine, your Kasa or Alexa app may be outdated or incorrectly configured. 

Too much distance or physical obstructions between your Kasa Light and Alexa device are other possible reasons. Lastly, though that happens rarely, there may be some issues with your Kasa or Alexa device.

Once you’ve identified the root cause, resolving the issue becomes straightforward.

Moving forward, we’ll break down these potential causes and give quick and easy solutions. 

Troubleshooting and Fixing the Kasa Light Not Responding to Alexa

Understanding the problem is half the battle. Let’s explore the common reasons for the unresponsiveness and how to tackle them.

1. Connectivity Issues

More often than not, when your Kasa Light becomes unresponsive to Alexa, it’s because of a connectivity issue. There can be a number of scenarios.

Connectivity Issues

Wi-Fi Network Discrepancies: 

Both the Kasa Light and Alexa need to be connected to the same Wi-Fi network for seamless communication. If they are connected to different networks, they won’t be able to interact with each other.

Therefore, make sure your Alexa device and Kasa Light are connected to the same Wi-Fi network. To do so:

  • Open the Kasa app on your phone.
  • Tap your Kasa Light from the list of devices.
  • You’ll find an option to view network information under Device Settings.
  • Make sure the device is connected to the correct Wi-Fi network, especially if you have multiple networks at home.

Weak Wi-Fi Signal: 

If your Wi-Fi signal is weak or unstable, your Kasa Light and Alexa device may intermittently lose connection. As a result, there may be communication breakdowns between the two– leading to unresponsiveness.

To fix this, you can Reboot the Router in the following way:

  • Turn OFF the router and unplug it.
  • Wait for 30 seconds and plug it back in.
  • Turn ON the router and wait for all lights to stabilize.
  • Reconnect your devices and see if they’re back in sync.

Router Overload: 

Sometimes, if there are too many devices connected to a single router, it can become overloaded and might not allocate sufficient bandwidth to each device, causing connectivity issues.

Router Overload

If that’s the case, you should take some load off your router and disconnect devices that are not in use. After doing so, you can also try rebooting your router, as explained above, for better results.

2. Kasa App Malfunctions:

Alternatively, your Kasa app may be malfunctioning due to the following reasons:

Outdated App Version: 

If the Kasa app is not updated to its latest version, it might have bugs or compatibility issues that prevent it from communicating effectively with Alexa.

Follow these quick steps to update your Kasa App:

On Android phones:

  • Open the Google Play Store on your smartphone.
  • Tap your profile icon on the top right corner.
  • Select the Manage Apps and device options.
Manage Apps and device
  • Now, tap See details under the Updates available section, find the Kasa app, see if an update is available, and update it.
  • Alternatively, you can just tap Update all and let Google Play automatically update all the apps, including the Kasa app (if an update is available for it).
just tap Update all

On iPhones:

  • Navigate to the App Store > tap your Profile icon on the top right.
  • Scroll down to find the list of installed apps on your iPhone.
  • Find the Kasa app and tap the Update button next to it.

Note: If it shows the Open option instead of Update, the app is already up to date.

And now, your Kasa app will be up to date. But if you still continue to face issues with the app, you can uninstall and reinstall it.

Incorrect App Configuration: 

The settings within the Kasa app must be correctly configured for integration with Alexa. If there’s a misconfiguration, it can lead to the light being unresponsive.

Here are a few things you can do to configure the Kasa app correctly:

  • Launch the Kasa App on your device.
  • Once inside the app, you’ll see a list of all your Kasa devices. If you don’t see the device you’re having issues with, it might not be added or properly configured.
  • Select the device that’s causing issues.
  • Tap the gear icon (on the top right) to see the settings.
  • Ensure that the Remote Control setting is enabled.

This allows you to control the device when you’re away from home and is essential for integrations with other smart platforms.

  • Also, ensure that the configurations are consistent across both platforms– Alexa and Kasa. For instance, the device name in Kasa should match what’s in Alexa.

Remote Control Disabled: 

For Alexa to control the Kasa light, the remote control feature must be enabled within the Kasa app. If it’s disabled, Alexa won’t be able to send commands to the light.

Here’s how to enable remote control on the Kasa app:

  • Open the Kasa app on your phone.
  • Find and tap the problem device from the list of connected devices that appear on the screen.
  • Access device settings by tapping the gear icon on the top right.
  • Now, enable the Remote Control setting if it is disabled.

This way, you will be able to control your Kasa Light from a distance by using your mobile phone or digital assistants like Alexa.

3. Alexa Device and App Issues:

Your Kasa Light might not respond to Alexa because of problems with the Alexa device or app. Here are a few things you can do to troubleshoot and solve this issue.

Outdated Alexa Software: 

Just like the Kasa app, the Alexa device’s software needs to be up-to-date. An outdated version might have compatibility issues with newer Kasa light models or features.

The Alexa app typically updates itself. But here’s how you can update the Alexa app on your phone manually:

On iOS:

  • Open the App Store on your iPhone.
  • Navigate to the top right and select your Profile.
  • Now, scroll down to Available updates, and if you see Alexa in the list, update it.
  • Or else, you can just tap Update all and get all your apps updated at once.

On Android:

  • Launch the Google Play Store.
  • Navigate to the top right and tap your Profile.
  • Now tap Manage apps and device.
Now tap Manage apps and device
  • Under the Updates available section, you can either choose to See details, find the Alexa app, and update it (if an update is available).
  • Alternatively, you can just tap Update all, and Google Play will automatically update all the apps that have updates available.

Device Discovery Issues: 

Alexa needs to discover smart devices before it can control them. If there’s an error during this discovery process, or if the Kasa light wasn’t properly added to Alexa, it can result in unresponsiveness. 

To make sure Alexa correctly discovers the Kasa Light and connects to it, do the following:

  • Open the Alexa app.
  • Go to Devices and delete the Kasa light.
Discover Devices option
  • Use the Discover Devices option to re-add the Kasa light.

4. Firmware Issues with the Devices

Outdated Firmware: 

Both Alexa and Kasa devices operate on firmware that needs periodic updates. Outdated firmware can lead to compatibility and communication issues. To fix this, simply update both devices.

Outdated Firmware

Here’s how to update firmware on Echo/Echo Dot (any generation):

  • Make sure your Echo or Echo Dot is turned on and connected to the Wi-Fi.
  • Say: “Alexa, look for software updates.”
  • Give Alexa a moment to check if there is any update available.
  • Alexa may confirm to update the device software if it finds any updates available.
