TP-Link Kasa Communication errors OH 4.0.4

Since moving to OH4.0.4 and applying all current updates, I am starting to see many TP-Link communication errors. They are random on both device and frequency. They may be offline for 2 minutes or 10 minutes. It is totally random. It was working great on OH4.0.3.

Thank you.

Same here.

There were no changes in the binding, so not sure what might be the issue. I haven’t tested 4.04. yet, so can’t confirm. Do you have ip address configured?

I had this same issue before moving to 4.0. I rebuilt my servers as OH4.0 instead of upgrading. At that point things cleared up and I had very few comms issues on TP-link. My logs were looking very clean. I did all the updates as they came out and things were still good on 4.0.3. Since moving to 4.0.4 with all the current updates, I am seeing a lot of comms errors.
All 42 of my TP-link devices have static IPs. No pattern to the errors. Some devices are inside, some outside, some near, some far.
I do hope that one day the binding will be updated to include the new Matters devices. I am holding off on adding any of them for now.
I do have a 4.0.3 backup that I may try to see what happens.

Have a look over here : [TapoControl] - Control Tapo Smart WiFi-Devices with Openhab - Official Support Thread - #357 by Dadobam

That works for the Matters devices, but that is low priority for me. This comms error is more important.

Sorry I often confuse TP Link and Tapo.
I have no issue at all with my TP Link devices. But I had your error on my Tapo devices that had been automatically updated (firmware)

I switched back to OH4.0.3 and have not had a TP-link comms error since.

I have since noticed a number of errors even on 4.0.3. I have since changed back to 4.0.4. I rebooted a couple times and still had this issue. Two days ago, I rebooted my routers, and the problem seems to have improved. I am down to just 1 or 2 devices going offline maybe once or twice a day.
