Hi
Is there a way to get around the 160 character limit of the node-red-contrib-cast node?
Can you, for example, make the mp3 separately and then play that mp3?
Regards
Christophe

Maybe I didn't explain it correctly. You can put text in the cast node and it automatically converts it to mp3. The problem is that you can only do this with 160 characters. I want a way around that, so I was thinking to create the mp3 separately via another node, store that mp3, play it via the cast node and then delete the mp3.

Yes and with those msg properties you can play the mp3.
