Hello
I was looking for this kind of node red programam, for that I thank you
Albeit I am not able to get it to work.
Am using the node Sonos ver 4.1.0 , and it does not recognise the http link.

Anther question is that if I connect the output of the wavenet, for sure using the change node as per your exemple, I cannot get my sonos working either.

The erro is not in the configuration of the nodes, because i got the mp3 file from wave net and also manage t get the status of the Sonos.

I suspected that could be the syntax out of the node you called tts + reset volume
i have tested

I think the Sonos node syntax has been changed since I made the flow. Still works with the old Sonos node.

Will try updating my Sonos nodes and see if there is anything I need to change.

Should work with the latest version of node-red-contrib-sonos-plus now.

Shall I use the same flow ?

…
