Hey Nick!
No errors. But once the speech has finished the music doesn't resume. Even if I try and start the music manually i.e. via the Sonos app there is no audio (though the track progresses etc. so everything seems fine).
Also, did you add the method so that speech can be created in python i.e. dynamically?
Great stuff though - much appreciated
Cheers
BTW the custom states all ;'filled' in once the speech ended but were still blank before even though track was playing.
