Mho: my setup is containerized and I suspect there is no communication possible between the IP’s in use by the container and my regular network. But how to solve this is out of my league 
I want to use the HA local file storage because the NAS goes to power save. It takes up to 30 sec’s to start. That is too long for playing a doorbell sound that is required instantaneous play.
So from here I continue on the HA forum; thats why I created the table to have a nice starting point
Thanks for the continuous support.

OWK
