@caywilliams,
If you add one, or more, of the following speakers to your Sonos setup (devices listed in no particular order)…
- Roam/Roam SL
- Move 2
- Era 100
- Era 300
Then you can Bluetooth stream the TT audio to any of these listed newer speakers and whilst they are connected over the local network (wired, or wireless) to your Sonos One’s & Sonos Move’s you can either group all, or some, of the speakers together to playback the playing TT audio received from that TT. This however cannot be achieved with your current hardware until you add one of the listed newer devices to your Sonos system.
I’m not sure how reliable the grouped setup would be, it’s a case of trying these things to see how well they may work with your local network.
