Hi All,
This issue is on an existing system running with multiple Kasa HS200 devices which are working without problem. I’ve added another TPLink Kasa HS200 switch which is a newer version: hardware (ver 5.20) and firmware (ver 1.0.3). The Thing adds correctly but it never comes on-line, instead it is failing with a connection refused error. An examination of both the log file and a Wireshark capture of the nic traffic show an issue during initial handshake.
This is the Thing:

Here is the logfile capture

It retries four times.
This is an image of a Wireshark capture which basically confirms the connection refusal. This exchange happens first:
And a few tics later this one confirms the refusal. This is repeated for each subsequent retry:
The switch does install correctly in the Kasa app and all switches are accessable from the app. I’ve tried this using the 4.2.2, 4.3.0, and 3.4.5 versions of OH with no difference. I’ve also reduced the variables and configured a test private network containing only the switches, OH server and my router. Also to no avail.
Has anyone else seen this? What am I missing something?
Perplexed,
