HS103 and KP400 smart plugs "flashing" (resetting) for 1 second randomly
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
For several weeks now, I experience a strange new issue with a few HS103 smart plugs and also with a KP400 exterior smart plugs where the plugs seem to quickly reboot and cut power for like 1 second, so obviously it makes the lights (or any device) to turn off for like 1 second. I clearly hear the relay inside the smart plugs who "trig" and make the clicking noise.
I am working myself in IT for like 20 years now and I am trying to understand what could be the condition where the HS103 and KP400 relay will "trig" for a second randomly? Obviously it doesn't have nothing to do with the power because in the same room that the HS103 I also have a smart battery UPS who monitor the power and it doesn't detect any power variation.
Is there any Wi-Fi relay condition where the relay inside the plugs can "click" for a second? I have a TP-Link Omada mesh Wi-Fi system at home and one thing I can suspect is that the HS103 and the KP400 smarts plugs may "roam" from one AP to another for any reason... but I am not sure if any Wi-Fi signal issue can make the relay to trig a second...
I have more than a dozen of HS103, HS105 and HS200 but only 2x HS103 and 1x KP400 are affected by this problem yet... but they are not in the same room, nor on the same electrical circuit as well.
Any suggestions???

Created this account to say I'm having the same issue with all 5 HS103's I purchased last month. They will randomly flicker off then on. Real pain in the butt when I used one to control the power to my 3d printer and it killed the print halfway through.
I might still be able to return these back to Amazon and get some Wyze ones if there isn't a fix for this :(

@bugbbq I am using many TP-Link Kasa products since 2017 without a single issue, they are extremely reliable and the Kasa App is really well done, I had several other brands of smarts plugs/switches over the time and sold them all to replace with more TP-Link Kasa devices. My personnal advice would be to keep them and hopefully TP-Link will find the solution soon... I am exchanging email with them almost every days for the past few weeks and they really want to find the solution of this issue.

Thanks for the encouraging words. I'm hoping for a fix, but I'm also a little worried about the lack of response I'm seeing from TP Link about this issue.

@bugbbq well I have pretty regular follow-up from TP-Link on the issue, however the thing is that they actually can't reproduce the issue inside thier test lab and they suspect that the issue is caused by something in the customer environment, such as another peripheral connected to home network than may send a command over the network that could cause the HS103 to "crash" and reboot but that doesn't affect other TP-Link Kasa products such as older smart plugs (HS105) and also wall switches are not affected.
I am currently trying to use a network packet sniffer (capture utility) on my own home network to log packets sent over the network by other peripherals and see if I can track something specific at the exact moment that the HS103 are crashing and rebooting. But it's not that easy to do because I capture a few millions packets per hour on my home network (I have a LOT of devices) and sometime the HS103 will take several hours to crash/reboot.
