Sorry to steer this thread off-topic, @Matthew!
I will get it back on track by saying that I’d also love to see TTS support on the Hubitat hub, but this has already been asked on this thread, and @bravenel stated that it’s on their roadmap.
I don’t have enough know how to understand whether the addition of a textToSpeech() function alone will allow for TTS notifications to be forwarded to a DLNA media renderer, as is done with Ule’s solution, but that’s what will be necessary for your Fabriq Riff and Chorus speakers to work.
I also have a couple of DLNA MR capable speakers, not Sonos, so I’m in the same boat as you and @Cobra.
