Our verdict
Sonos's top soundbar: 9.1.4 Dolby Atmos from 14 drivers and the Sound Motion woofer, with HDMI eARC and AirPlay 2. It costs £949 to £999 before you add a Sub, so it only makes sense for a proper TV room. In HA it is the only Sonos device with a Dialog Level select, which is useful for a late-night preset.
What can Home Assistant control on the Sonos Arc Ultra?
| Control | Type | What it does |
|---|---|---|
| Media player | Media player | Playback, volume, grouping, play_media and TTS announcements; supports Sonos favourites as sources. |
| Bass / Treble | Number | EQ levels exposed for every Sonos device. |
| Loudness / Crossfade / Touch controls / Status light | Switch | Per-speaker toggles available on all devices. |
| Alarms | Switch | One switch per Sonos alarm; leave about a second between rapid updates or the speaker can drop offline until a power cycle. |
| Night Sound / Speech Enhancement | Switch | Home-theatre toggles for late-night TV; useful as a bedtime automation. |
| Audio input format | Sensor | Shows the incoming format (e.g. Dolby Atmos), handy for scene triggers. |
| Dialog level | Select | Arc Ultra only; switch dialogue enhancement from automations. |
Sonos integrates natively in Home Assistant over the LAN (local push, per the HA docs), with no cloud account needed for control. Media player entities handle playback, volume, grouping and announcements. Prerequisite: UPnP enabled in the Sonos app, and HA must reach the speakers on TCP port 1400 or it falls back to slow polling.

Frequently asked questions
- Does the Sonos Arc Ultra work with Home Assistant locally?
- Yes. The Sonos Arc Ultra is controlled locally in Home Assistant through a built-in Home Assistant core integration (sonos), so it keeps working if your internet connection or the Sonos cloud goes down. Control and state updates stay on your own network.
- Which protocol does the Sonos Arc Ultra use, and do I need a hub?
- The Sonos Arc Ultra uses Wi-Fi and Bluetooth. To pair it with Home Assistant you need no hub — it joins your Wi-Fi network directly; or a Bluetooth adapter on your Home Assistant host or an ESPHome Bluetooth proxy. Sonos's own hub is not required when you integrate through a built-in Home Assistant core integration (sonos).
