7 Ways To Fix Kasa Light Bulb Not Working With Alexa.

Connecting Kasa Bulb to Alexa is very common among people who want to increase home comfort and take control of the lamp using their voice.

This combination helps users integrate the Kasa bulb with the rest of smart home devices and manage them from a single platform, as well as create routines and schedule when the light should be on and when to turn it off.

But one of the most common issues is that sometimes the Kasa bulb stops working with Alexa, which is a problem for those who are used to controlling this gadget from this third-party app.

So, in the next sections of this blog post, I will give you all the tips and tricks that you can use when the Kasa Smart bulb stops working with Amazon Alexa.

How Do I Fix Kasa Light Bulb Not Working With Alexa?

There are many causes that can prevent your Kasa bulb from working with Alexa, including connectivity issues, outdated firmware or apps, or a problem with your router or Echo devices.

In this article, you will find 7 solutions that you can try to fix this problem, so keep reading.

One: Turn On The Wall Switch.

If your Kasa bulb is connected to a traditional wall switch and someone uses that switch to turn the lights off, this may be the main cause of the problem as it will cut all power to your lights, which means that your bulb will not communicate with your mobile or router (also the Alexa app) until you turn the switch back on.

The solution here is to tell all your family to not turn off the bulb from the switch, but this rule will not be respected when a guest comes to your house and he used to turn off the lights from a switch, so you can use a light switch guard to completely hide it.

You can also change your traditional wall switch with a smart one like “Lutron Smart Lighting Dimmer Switch”, which will completely solve this problem.

Two: Power Cycle Your Router & Your Echo Devices.

If you notice that the source of your problem isn’t coming from the switch, you can power cycle your router and the Echo device you’re using to control the Kasa bulb.

Power cycling your router may fix the problem if it’s caused by connectivity issues, this process will clean out the device’s short-term memory and allow the router to re-select the least crowded channel for each frequency, which means a stronger connection to your device.

Power cycling your Echo device will increase the performance of the device and fix issues that are caused by the software, so you can try it to resolve your issue.

Some people use their smartphones and tablets to control the Kasa Bulb from Alexa, if you are one of them try restarting your phone and tablet as this will increase the performance of the OS and also fix errors in the Alexa app that you may be facing right now.

Three: Update The Kasa Bulb Firmware & The mobile apps.

An update is necessary to keep your devices and apps running smoothly and avoid issues like the one you’re facing right now.

So make sure to update the firmware of the Kasa bulb and the Echo device you’re using to control the bulb, updating the phone OS is also recommended to improve apps performance.

I also suggest that you update the Alexa app and the Kasa Smart app to fix the existing bugs that might be causing your problem.

Four: Reduce Wifi Frequency interference.

As we mentioned earlier, your Kasa bulb may stop working with Alexa due to connection issues, and one of the causes behind this problem is Wifi frequency interference.

This interference may be caused by equipment in your homes such as wireless speakers, baby monitors, walkie-talkies, and garage door openers.

This problem can be solved by including better placement of access points, balancing traffic between the 2.4 GHz and 5 GHz bands, beamforming, and turning off devices that may cause interference like the ones we mentioned before.

Note: The Kasa light bulb work only on the 2.4 GHz channel, so make sure to connect it to this frequency.

Five: Expand Your Wifi Signals.

Another cause of internet connectivity issues is that your devices, including the Kasa bulb, aren’t receiving good signals from your home Wifi router.

Here I suggest extending the signals by moving the router to a place where it can broadcast its signals to all home devices, or you can use a Wifi range extender, or set up a mesh network if your house is large and contains more than one floor.

Six: Reset the Kasa Bulb & your Echo Device.

Factory reset is often done when an electronic gadget gets into trouble and is considered an effective tip to fix common issues. So I recommend resetting your Kasa smart bulb when it’s not working with Alexa.

To reset your bulb you need to turn the light switch controlling the bulb to the OFF position, then flip the light switch on and off 3 times, 5 times, or 10 times depending on the model you have.

You can also implement a factory reset on your Echo device if you’re controlling the Kasa bulb from an Amazon Echo speaker or display and you suspect that they’re the source of the problem.

To reset Echo Dot (2nd Generation):

  1. Press and hold the Microphone off and Volume down buttons.
  2. Wait for 20 seconds until the light ring turns orange.

To reset Echo Dot (3rd or 4th Generation):

  1. Hold down the Action button for 25 seconds.
  2. The light ring will pulse orange, then turn off.
  3. Wait for the light ring to turn back on and turn blue.
  4. The light ring then turns orange again and the device enters the setup mode.

Here’s how to reset the Echo Show:

  1. Press and hold the Mute and Volume Down buttons until you see the Amazon logo (about 15 seconds).
  2. When prompted, follow the on-screen instructions to set up your device.

Seven: Factory Reset Your Router.

The last solution I recommend is to reset your router, this will restore them to factory default settings and can fix connectivity issues and improve speed and signals while maintaining a reliable internet connection at all times (this can help your Kasa bulb to easily connect and communicate with Alexa).

Reset the modem:

  1. Ensure that your router is on.
  2. Use a paperclip and hold down the reset button for 30 seconds.
  3. Release the button and wait for the router to power back on.

Final Words.
