Hello all. I have a bunch of HS200 switches around my home. Last Friday/Saturday, I installed 3 new HS200's. These all came in a 3 pack and are hardware version v5.26. All of the other HS200's I have are v5 or older.

They were fine upon install and were working normally. Overnight Tuesday, something happened. I'm assuming they did a firmware update. They are now on version 1.0.2, but I'm unsure what version they were on prior. Here is what is happening.

1. In the morning, I got into my home office (Where one of new HS200's are, controlling my fan) and noticed the automation for my fan from Home Assistant didn't work. I logged into home assistant and found that the switches were showing offline, and new switches with the same name had appeared in the same room. I rebuilt my automation for the *new* devices and just assumed it was something weird with home assistant.

2. I noticed that homeassisant now has trouble turning the switches on and off. It sometimes takes 3-5 seconds to work.

3. I've noticed the 3 HS200 v5.26's now all go to either orange or red LED status. Like they're not connected to the internet. (Wifi is very strong, I have multiple access points in the home). When they're either red or orange, they sometimes will appear in online in the kasa app and work normally. Sometimes they show offline. For instance, right now my office fan switch is Orange. But it works fine in the Kasa app. And via home assistant (However home assistant is sometimes slow).

4. In all cases, if they are orange or red, I can click the reboot button at the bottom right and the switch returns normally. But it goes orange or red again sometime later (Perhaps 30-45 minutes?).

5. Only the v5.26 switches are doing this. All other HS200's, and the few HS200M's (Motion) that I have, are all working perfectly normal.

6. Sometimes when the switch is orange or red, and offline in the Kasa App. I can see it's still connected to my wifi access points. I can "kick" it to force it to reconnect. When I do this, It will not reconnect unless I reboot the switch by pressing the bottom right button.

Best I can tell, something happened Tuesday night that made these switches really unstable. Is there anything I can do to help TP-Link investigate this? They all worked fine before Tuesday night / Wednesday morning.

Please note, I guarantee this is not a connectivity issue. I'm a network engineer by trade and connectivity was the first thing I looked at.
