@Glovej 

Good day,

Thanks a lot for your time and patience.

May I know the model number of your home router?

How long have you had the device and when did this issue start?

And I could see from the cloud server that there are several HS200 and HS210 under your TP-Link ID, was HS220 the only one who had this issue?

What is the model number of the lamp controlled by the HS220 and can I have a link of the product overview about the lamp?

Thank you very much.

I have the exact same problem, same switch (HS220 V2.0 on 1.0.3 firmware). I have 3 of them and they all do the same problem. They are on like they should, but suddently turn off for a split seconds, then back on.

@Glovej  Having the same problem with one 3way switch, but no problem with another. Light flashes on then immediately off. (never off then back on) Using Orbi mesh RBK50, satellite less than 30 feet away and direct line of sight.  HS 210 v.2 firmware 1.1.4.  MAC ending 43:25. Switch connected to basic incandescent light wall fixture with plain bulbs

I just bought these and have 3 dimmer switches installed replacing my current non smart dimmers.  I have the same issue on 1 of 3.  I have my lights on and suddenly it goes off for a split second and comes back on quickly.  .  This has been going on for the last 2 days.

Model HS220

Hardware Version 2.0

Firmware Version 1.0.4

@Glovej I have 3 HS200 switches that randomly turn off then back on too. They don't happen at any apparent interval, just randomly a few times throughout the night. Curious to know if you were able to resolve the issue?

Hello, I am having what seems like the exact same issue but with my 2x HS200 (non-dimming) wall switches.  Several times throughout the day, the connected lights (2 banks of fluorescents) will turn off for a split second and then turn on again.  From where I sit in my office, it appears that they both do the same "flicker" at the same time.  I have several computers and other devices in the rooms and they aren't affected as if it was a power flicker from the breaker box or grid.  I don't see any particular pattern or timing of the flickers, they will be fine for hours and then flicker off and on.

Both HS200 units are HW v3.0, FW v1.1.4, and are connected to my 2.4ghz WPA2 wifi network.  They are properly installed with neutral-wire connected as per the instructions.

Please let me know what can be done to further troubleshoot.

I'm experiencing the off/on, and on/off as well. I have single pole, 3 way, smart outlets, dimmer, and power strips and I have seen all of them exhibit this behavior. I have somewhere between 60-70 tp-link smart devices, and if I have another night like last night I'm going to rip all of them out! From 2am - 5am my Master Bathroom light would turn on and then off every 7 minutes!

It's almost like the switch is resetting on it's own. I've seen it happen and immediately looked at the switch. The Wifi light is flashing green like it's searching for Wifi.

There isn't a pattern to this either. I can go a couple days without it happening, and then I can have a day where there is a switch somewhere in the house doing it every few minutes.

I use the Kasa app to manage them, and also have that app linked to my Amazon Alexa app.

All have current firmware, and all apps are up to date.

I should add that I've used tp-link switches for years and this behavior just started happening to me a few months ago.
