Hi @Mik, unfortunately, the TTS (Text-to-Speech) feature is not available on the Sonos speakers any more after the Sonos integration update late last year. So any 3rd party integration will not be able to send text for Sonos to announce except the SmartThings app at this point. The workaround from SmartThings community is to host the audio mp3 file somewhere and have Sonos to play it as the announcement.
