Hello, would you please tell us more details about the issue? When you set up the power strip on Kasa app, there should be an option for KP303( the same option for HS300).

 

What's the light status of KP303? Can you control them with the Kasa app? What appliances are connecting to the KP303? Are they under control? Have you done any troubleshooting before?

 

Good day.

I have the same problem.  I have three KP303 UK Power strips.  They worked fine for a few months.  But Now, all of them have the same issue each with 1 socket failure.  Three power strips have one socket is always ON (Usually the third one) even though I press the ON/OFF button the light go on and off. 

@TP-Link Hi, is the KP303 1 outlet failure resolve?  I have similar issue whereby my KP303

One socket middle plug is always ON (current flowing) no matter I press the ON/OFF button the light goes on and off.  Thanks

Hi, thank you very much for your kind reply.

Sorry for the delay.

We would like to forward your case to the senior engineers for further assistance.

At the same time, could you please help me check the following information:

1. When you said one socket is always ON (Usually the third one) even though I press the ON/OFF button the light goes on and off, did you mean it would always provide power for the device connected behind no matter it is on or off?
2. Could you please send me a private message about the SN number and MAC address of these 3 power strips?

Thanks a lot and wait for your reply.

 

I also have the same problem with a KP303 bought May 2021 (four months ago) - one socket permanently live. The indicator light goes on and off as normal and I hear a small click switching it on or off, but the socket stays live. I think it's a faulty relay. The load is less than 300W.
