is it possible to configure a pa which will be used by HA? I have a line coupler in my system which filters telegrams based on source pa and target ga. So HA needs to stick on a physical address which do not change during restarts.
In xknx there is a own_address option, but this seems not work in HA.
Now it defaults to 15.15.250 - you can configure a dummy for this in ETS.
Or you use tunneling, then the tunnel server should provide a IA for the connection.
have a try! There have been changes to this behaviour recently, but I personally never used xknx.yaml.
Maybe try to configure the general and connection block in xknx.yaml and just the devices in HA.
Note: you will have to update your configuration with the next release of HA anyway, maybe then you can already configure the individual address from HA too.
