Home Assistant integration for StormAudio processors

Home Assistant custom component integration for StormAudio, Focal and Bryston processors.

Supported devices

Integration supports the StormAudio family of processeors that use the published TCP/IP API (port 23, firmware 4.6r1 or later) platform as of August 2026:

• StormAudio ISP and ISR series
• Focal Astral 16
• Bryston SP4

Focal and Bryston branded units share the same API with one documented exception that Front Panel Color) aren't available on those brands.

This is the most feature rich, and robust Home Assistant integration for StormAudio.

Entities

• media_player - main device control (power, volume, mute, source, sound mode)
• switch
  • Mute, Power
  • Dim, Dolby Virtualizer, Dialog Norm, Center Spread, LFE Dim
  • Per zone: Mute, EQ, Binaural Mode
  • Per trigger: on/off
• select
  • Source, Source (Zone 2), Preset
  • Dolby Mode, Auro Preset, SphereAudio Effect, Loudness
  • DRC, IMAX Mode (on/off/auto)
  • Front Panel Color, Front Panel Standby Delay
• number
  • Volume Level
  • Center Enhance, Surround Enhance, LFE Enhance, Bass, Treble, Brightness, LipSync
  • Auro Strength, Dialog Control
  • Front Panel Standby Brightness, Front Panel Active Brightness
  • Per zone: Volume, Bass, Treble, LipSync
• sensor
  • Surround Mode (+ engaged attribute), StormXT
  • Video Resolution, Video Encoding, Video Refresh Rate, Video Input, Video Sync, Video Copy Protection, Video Color Space, Video Color Depth, Video Mode (one set per HDMI output - see Notes)
  • Active Speaker Config, Sample Rate, Stream Type, Channel Format

Per-zone and per-trigger entities are created dynamically based on what the StormAudio device reports at startup (its zones.list / trigger.list broadcasts). If you add or rename zones/triggers on the unit itself, restart the integration (or Home Assistant) to pick up the change.

The protocol client (stormaudio_telnet/) is vendored directly in this integration rather than pulled in as a separate pip dependency.

Notes

• Video info is read for every HDMI output listed in HDMI_OUTPUT_IDS (stormaudio_telnet/constants.py) - HDMI OUT 1 and OUT 2 by default. The HDMI OUT 1 sensors are enabled by default. The HDMI OUT 2 sensors (named ... Video Resolution (HDMI OUT 2), etc.) are created disabled; if your display is on HDMI OUT 2 or you run dual displays, enable the ones you want from the entity's settings (Settings → Devices & Services → StormAudio → entity → gear icon → Enable). No code change or restart config is needed. If a future unit exposes more than two HDMI outputs, add the output number to HDMI_OUTPUT_IDS and the client and sensors pick it up automatically.
• Zone sub-controls (mute/bass/treble/eq/binaural mode/lipsync) rely on the StormAudio device resending its full zones.list broadcast whenever any zone field changes (per the API doc) rather than parsing each zone's individual per-field echo separately.
• Some controls require licenses/hardware to be present (StormXT, SphereAudio) - when not licensed, the StormAudio device returns error, which shows up as unavailable for the corresponding sensor/select rather than a numeric value.
• For Bryston/Focal-branded units, Front Panel Color isn't available; these devices do not respond to that command so the entity will always show "unknown".

Installation

This integration is not in the HACS store, so install it as a HACS custom repository (recommended) or copy the files in manually.

HACS (recommended)

1. Go to HACS → ⋮ (top-right menu) → Custom repositories.
2. Add this repo URL - https://github.com/Ltek/StormAudio - with category Integration.
3. Find StormAudio in the HACS list and click Download.
4. Restart Home Assistant (Settings → System → Restart).
5. Add the integration: Settings → Devices & Services → Add Integration → search for StormAudio, then enter your processor's host/IP and a name.

Manual

1. Copy the integration folder to your Home Assistant config directory so the files land at: /config/custom_components/stormaudio/ (i.e. /config/custom_components/stormaudio/manifest.json, .../__init__.py, .../media_player.py, .../stormaudio_telnet/, etc.)
2. Restart Home Assistant (Settings → System → Restart).
3. Add the integration: Settings → Devices & Services → Add Integration → search for StormAudio, then enter your processor's host/IP and a name.

NOTE: restart is required after installing or updating it - a config-entry "Reload" will not pick up new code.
