Yes it definitely seems to be a cloud problem. I also have a bunch of smart plugs that turn off and on at random, but always simultaneously.

If it were a hardware problem it should happen independently for each switch.

I was in doubt whether it was a TP-Link problem or a Google integration problem, but it looks like it's all on TP-Link given the posts from others.

The above solution is very complicated and I do not intend to readjust everything and hope that it will help.

I am currently testing smart products from Sonoff and I must say that they are very successful and these suction cups do not have this problem. Their big advantage is that you can define what should happen after a power failure - so you define the state of the relay after a power failure. Which in my case of using the Fridge is exactly what I was looking for.
Although you write that you do not recommend using smart sockets on devices such as refrigerators and others, then what is a smart home for when you can't create your own comfort !?

I assume that your problem will be solved in some future firmware. Until then, I will not use these devices where I need them to be on for most of the time.

@Edwardon Good day, 

We appreciate your feedback, sorry to hear that its looks a bit complicated, the major troubleshooting is to create a Guest Wi-Fi on router, and connect smart device to that Wi-Fi and see if is gone or not. If the issue is gone, connect phone & other devices to that Guest Wi-Fi one by one and see if any certain device will trigger this issue. 

We will update on this thread if there is an update for this issue, kindly keep an eye on this thread,  thank you for your understanding~

I have over 30 HS103 smart plugs at home and at my business. They ALL flicker on and off at the same time since I bought them. In both locations. 

I have contemplated replacing them all but it takes a long time to replace 30, plus the cost. 

I have kept up to date on this post, I have literally tired everything. I thought it maybe a bad batch but I bought them at different times and different places.

I know its not the router because this is happening at 2 different locations. 

I have 2 different usernames, one for home and one for business. But both flicker. 

All up to date firmware.  Ive called tplink and they gave me the run around, like every response they gave on this post.  

Its the product 100%... Im wondering when TP-Link is going to replace these trash plugs. A good company would be honest about the issues and make it right. :(

@Ryanskel22 Good day,
