Denon HEOS
Controls Denon HEOS multi-room audio over the HEOS CLI protocol. One connection reaches the whole system, and each player is addressed by its player ID — so every HEOS room shows up as its own device.
Connection
Section titled “Connection”- Network — HEOS CLI over TCP port 1255. A single persistent connection serves the whole household.
- Host — the address of a HEOS player to connect through.
Each player is addressed by its playerId, and the driver bridges those out as individual room devices.

Reports playback and volume state per player. It carries the audio, media.player, and bridge traits — the bridge trait is what turns each HEOS player into a separate child device.
