The brand new replacement unit they sent is now crashing--light stays solid white but none of the buttons do anything while in the crashed state. Looks like they replace broken units with even more broken units. Good stuff.

@Robautomator This is not looking too good.

I am also experiencing random power cycle events on a variety of HS300 devices I have around the house. It will be very disappointing if I have to migrate to some other solution...

@bcrefugee 

Good day,

Thank you very much for your time and patience.

Sorry for the delay.

May I know where are you located and how long have you had the devices?

We had several feedbacks recently and our senior engineers are working on it; and we also would like to collect some sample devices for further analysis.

Thank you very much for your understanding and support.

@Brook If you wish to have some samples for your engineers then they can have both of mine.  Just let me know how you wish to proceed.  I am located in Madison, WI.

I have two HS300 power strips.  Purchased on March 20, 2019 and November 29, 2019.  They both randomly restart themselves.

Extra info: I have 7 of the HS110 power outlets and none of them restart themselves.  I do have a KL130 light bulb that randomly takes quite some time to connect to turn on or off.  I use only an Adriod app.

If you could replace these HS300 strips with multiple HS110 power plugs as a replacement.  That would be great but not required.  I was about to buy more power plugs since the power strips are a problem.

I chatted with L2 support today and they advised the following changes:

-Updating primary DNS to 8.8.8.8 and secondary DNS to 8.8.4.4 in your router settings. (How to do that varies by your router model.)

-Changing your wifi Control Channel to 1, 6, or 11, which usually reduces network interference.

-Deleting unit from app, factory restoring by holding the first outlet button (closest to USB ports) for 10 seconds, then reinstalling unit to the app.

No restarts as of the past hour or so, but will continue monitoring.

@Robautomator 

Thanks a lot for sharing.

Please feel to update here with further news.

Thanks a lot.

@MikeP That was my thinking--the solutions seem like a workaround for a firmware bug that causes a crash upon certain situations of lost connectivity. Cautiously reporting that I haven't had any restarts on either device (one original and one new RMA device) since implemeneting the advised changes.

@socon I bought 2 of these power strips and they both have random power cycling issues.  Which makes them unusable for anything important.  So, I replaced them with single Kasa smart plugs.  The 2 Kasa power strips are now disconnected and sitting unused in the corner.  Maybe TP-Link will come up with a solid update/fix someday???  Or, if they are listening, maybe a replacement for some Kasa single smart plugs.
