Disappointing to see one of my Tapo smart plugs has now failed.

  @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 I had mine for 3 years, that is since 2021 August. 3 have died,and its has been almost 3 years to the dot.

only a few months ..... plug was attached to a heatmiser smart heating controller box. The heatmiser box was rendered inop... probably as a result of the smart plug failure   @LOSFO 

  @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!!

  @SamDom Yep my experience also

  @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

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.

  @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!
