Using Home Assistant, my Konnected Relay outs stopped working on the update to HA Core 2021.3.0, but the sensors still work fine. I found I could revert to HA Core 2021.2.3 and things worked again, but I would like to eventually move to later core versions. I experimented with external_url and internal_url declarations as described in https://github.com/home-assistant/core/issues/47569 but could not get the konnected outs to work in 2021.3.0. I have always used NGINX so have an empty http: section in configuration.yaml.
Then I noticed from the error in the log output below that the ip address for the konnected device was not correct. In konnected.yaml, I had discovery to the default true and did not have host or port specified. (the port number below is correct, the konnected ip address is not correct). I changed my konnected.yaml to have discovery=false and specified the host and port explicitly (after setting a fixed IP address in the router for the konnected device). With this change everything worked fine on 2021.3.x.
My main question is why did discovery get the correct konnected IP address in 2021.2.3 but not in 3.x? And similarly how was discovery working anyway in 2.3 since I did NOT have the SSDP integration installed? I had been using Konnected without any problems since early 2019.
Here is the error I get in the log files:
> WARNING (MainThread) [homeassistant.components.konnected.panel]
