G'day folks,

Just chiming in to add to the list of people dealing with this. I've just had my first one die in the same fashion discussed by others here. Started with the occasional click and after turning it off last night and back on this morning it is now in rapid clicking mode. This is one of the older KP115 Kasa plugs that I have four of, with a bunch of Tapo P110's and P100's dotted about the house that I have purchased over the past 12-18 months.

I will likely be switching these units out to use on less critical appliances and gradually replace them as they die. I certainly won't be buying any more of them though.

  @thewatcher 

im having the same problem with my EP25 plugs from Kasa. Rapid continuous clicking with light flashing, 3 or 4 clicks per second, nothing plugged in, factory reset doesn't work. Has T-P link commented on or addressed this?

  @GordonFreeman  I have had exactly the same issue. It started yesterday a day after a firmware update clicking every minute or so, then got progressively worse until it's now clicking continuously. I thought I had a problem with my smart TV then remembered I had it plugged in via a KP115! So annoying.

  @keypickles  I've just lost 2 115s in as many week, constant clicking turning off and on, I bought 4 of them about 3 years ago. So I've replaced one of them with a brand new 105, well it's been boxed up on my self for 2 years, so will see if that' will do any better. One of the 115s that failed wasn't even used but it was plugged I. .

We can add another to the list as I discovered this happening to one of my Tapo plugs this morning (P110).

I have 5 Kasa plugs and 2 Tapo plugs. I don't know if there is any similarity in hardware between the brands because I've had no problems with the Kasa plugs, and now both Tapo devices have failed.

The first one is permanently on now and will not cut power, regardless what the switch is set to (it still toggles but makes no difference). I discovered the second doing the behaviour described above in my office this morning. It appears it could have been ticking on and off continuously for nearly two days which is worrying because it powers three devices (power to one device then two others running via USB). I'm just hoping no damage was done.

Really disappointed in TP-Link who I've used for various networking products over the years. Let's hope the Tapo lights I have are a bit more robust.

  @thewatcher holy excel sheet!  I just have to share my situation here.

I have been using my Tapo P115 (240V 16A EU version) plugs with Home Assistant since April 2024. Everything was working just perfectly fine until today, when all of a sudden during midday I started to hear rapid clicking noise and located it into the one of my P115 plugs. The plug in question has had a Intel NUC (~15 W consumption) connected into it this whole time straight and nothing special happened when it started to fail operate - no power outage or anything else and it's been connected into grounded schuko wall socket.

Reading this thread takes out all trust into these totally away  I have six of them already and just last week ordered ten more  Seems like I should not have replaced my half cheaper Chinese Cozylife smart plugs with these since they worked without any issues for a year now, just wasn't Home Assistant compliant and consumption metering wasn't that accurate, but got the job done someway.

This makes me sad and deeply disappointed because I have bought during the current year two WIFI routers, several security cameras and these plugs all from TP-Link for usage with Home Assistant, because I thought they would work seamlessly together, which they do, but now starting to fall apart. My enjoy of this recent setup has come to it's end since now I have to worry all the time when next item gives up

And to avoid unnecessary and possibly stupid questions; yes I have tried to troubleshoot this every possible way known to man. Automatic firmware update is scheduled to 04.00 - 06.00 and failure occurred around 12.40. So just to clarify, nothing happened when it died and there is nothing to do to bring it back to life.

Best regards,
SNAFU

P.S. TP-Link, get your sheets together, pls!

It doesnt matter if the device only cost 10 bucks, the issue is the manner in which it fails and the damage it can cause to equipment connected to it. Its failure mode is a design choice.

  @Hylian Can I ask how long you have had these before the issue happened?

I'm having the same but they have been operational for a couple of years. Trying to decide if I could have expected more from a 10 dollar device and make a deal out of it. 

  @LOSFO 3 years almost to the day, now two of original 4 I bought have failed, on opening them it is the same electrolytic capacitor that has failed that others have reported

  @SamDom Yep my experience also

  @vjbutt Hi, exactly same problem with two so far of my KP105 Smart plugs and exactly the same electrolytic has failed in both cases.  i did contact my local RMA but they wanted all sorts of registrations and I'm expected to pay the postage for return, not sure the effort is worth it.  While its within my expertise as a retired ElectroTechnical Officer to do the repair, I don't think I'll bother as any further failure that caused say a fire would allow TP to lay the blame at my door..  Frankly very poor cutomer service.  They MUST know by now from the numebr of threads on here that there is a failure mode problem with these plugs.  As you rightly say, most likely under specified components so they should be offering replacements without all the rigmarole..   I am considering contacting Trading Standards here in UK and will be making these problems known on the Which forums.  Thanks for your input. made getting them apart quite easy.  Cheers!!
