Announced at Google I/O this past year Google told us all Google Home devices were getting bluetooth streaming. Now it’s finally rolling out as users are seeing it show up in the Google Home App.
Google Home has always supported streaming audio, but that was as a Chromecast target. Your app needs to have Chromecast support baked in. Casting also requires an internet connection for most apps because the target is just reaching out to grab the feed. It’ll work just like any other Bluetooth audio device; when connected, all media audio will be routed through the speaker in Home. Also depending on your version of bluetooth it might drain your battery a bit more then casting.
This feature is rolling out silently to devices so open your Google Home app and look to see if it’s there and if not don’t worry it will be there soon!
