I think the Wiim app on Chromecast and Android TV would be great, I know you are able to stream to Chromecast as I use it to get a now playing screen on my Google nest display, but I find this can be fairly unreliable and often have to restart the screen to get it to show the now playing screen.
The group I formed to play to ie Wiim pro and Nest display is not always available to stream to.
