Right at the bottom of the docs there’s a section about disabling auto-discovery and specifying the IP addresses of the speakers - have you tried that?
You’ll need to give the speaker a reserved IP address on your router if you want to make this a permanent solution.
thank you.
I installed HA on a container
Do you know where the configuration.yaml is located?
I found this path in internet /usr/share/hassio/homeassistant/configuration.yaml but it seems that is not valid
thanks
