We’ll talk about what causes your Kasa Smart Plug to click on and off and how you can solve the problem.

Why is my Kasa smart plug clicking on and off? 6 reasons

#1: You have poor WiFi connection

Smart plugs use WiFi to connect to the internet and your home appliances.

They need stronger signals with comprehensive coverage and the ability to penetrate walls.

As a result, these devices need 2.4 GHz WiFi with a bandwidth ranging between 50 and 70 Mbps.

If you live in an expansive home or one with several walls, the WiFi router might not be able to reach the smart plug. The same applies if other devices are using up the bandwidth in your home.

The first step is to check whether the WiFi connection is working and has enough strength for the Kasa smart plug by:

  • Opening a different app or website. Use your phone connected to the WiFi to open a separate app or website. If it opens, then the WiFi is working, and the problem might be coverage.
  • Shorten the distance between the smart plug and the router. Try bringing the router closer to the smart plug. The issue should resolve if the router was too far, causing poor connectivity.

  • Electrocution.
  • Damaged appliances.

Don’t use the socket if you notice it’s faulty. You can identify a defective socket by:

  • Visual inspection. Look for any signs of wear and tear, such as cracks, burn marks, frayed wires, or missing parts. If you see any of these, then the socket is faulty.
  • Checking for power. Put the plug into the socket and check if it’s receiving power by looking at the LED light. There might be an issue with the socket if the light doesn’t turn on.
  • Crackling sounds. A crackling sound indicates poor wiring, which is risky for your home. The National Fire Protection Association (NFPA) denotes that more than two-thirds of home fires result from poor wiring.

Therefore, you should get a qualified electrician to fix the socket if you notice any of these signs.
