+For grouping HEOS media players together for synchronous playback you can use the `media_player.join` service. With the example service data payload down below you'll expand playback of `media_player.office` to the `media_player.kitchen` and `media_player.bathroom` players. Please note that all of the media players need to be HEOS players.

 ## Notes
 
-- HEOS groups are not currently supported.
 - Receivers with multiple zones are represented as a single media player. They will be turned on when playback is started, but cannot be turned off by the integration at this time.
