🔊 Speaker Group Card (`speaker_group`)

Group speakers together and set each one's volume, Sonos-style. One row per speaker: tick it to join the group, untick to leave.

Works with any media_player that supports grouping in Home Assistant (media_player.join / unjoin): Sonos, and other multi-room integrations.

In the builder (since 1.2.9): pick the main speaker and the others from your devices, name and reorder them.

✨ Features & Possibilities

The master first, with a speaker icon. The others join its group.
Tick a speaker: it joins the master right away (media_player.join). Untick: it leaves (media_player.unjoin). No "apply" button.
Live membership: the ticks follow the real groups, even when you group from the Sonos app.
Per speaker: volume in %, a volume bar to tap or drag, and mute / − / + buttons.
