Hi, power consumption is max.750W, typically it's drawing 1A～3A.

I think current draw is not trigger of inturruption. I can't find certain timing or trigger.

status LED lights off and on quickly.(only once at a time)

It was occured several times and it's make me unconvinient, I'm swapped out my HS105 to Switchbot smart plugs...but I'm using other devices with Kasa, I want use HS105 again.

Hi, when you use the HS105 with other devices, does it work fine? When you use it with the computer, it worked abnormal, you can check the computer's instantaneous power, excessive instantaneous power of appliance can cause these problems.

If the plug works fine with other devices, it is suggested to use them together.

I am also having the same issue:

HS110 ver2.0

Firmware 1.5.10

It was connected to my computer and all of a sudden, my PC just turns off. Initially I though that it could be an issue with my PC, but after many troubleshooting, it was frustrating to find out that it is actually an issue with the smart plug.

The smart plug would randomly just turn off and on by itself. When I remove the smart plug and connect it to another outlet without connecting any appliances to it, it still does the same thing: randomly turns off and on by itself. It was working fine for months when my PC was plugged to it and this just happened suddenly. Seeing an average power draw of 100-200W.

@MikeP I am actually using the energy monitoring more as I would like to monitor my energy usage from my PC monthly. I have contacted TP-Link, hope I can RMA it since it's a known issue.

@chengfatt  My sons lamp does this and I thought the bulb was going bad until I noticed my TPLink in wall switches doing it also from time to time. My home security cameras picked it up. The lights on the top are on one smart switch while the lights on the bottom are on a seperate one. Any idea what this could be?   https://youtu.be/w52c-My8Uq4

@chengfatt seem to be a problem that tp-link dont want to give a sh..t..widespread problem all across the device. Have a bunch of unusable hs-105 ans hs- 103 that give random flash when on. 

Hello

I have the same problem 2 device HS110 firmware version 1.0.5, HW 4.0
about three to five times a day, both of these drawers oscillate at the same time. It is always quickly switched off and on again, approx. 0.5 seconds.
I have a fridge permanently connected to one socket and an LED lamp connected to the other, oscillation is always observed on both devices at the same time.
Is there a solution to the problem? My impression is that the device oscillates based on some signal from the cloud.
