Home Assistant - ADAM Audio Control (A series)

Home Assistant integration for ADAM Audio A-Series studio monitors (A4V, A7V, etc.) via the AES70/OCA protocol over UDP.

Controls each speaker individually and provides a virtual All Speakers group device to control both monitors simultaneously from a single entity or dashboard card.

Features

Auto-discovery via mDNS (_oca._udp.local.) with manual IP fallback.

More alternative dashboard cards will be added soon.

Requirements

• Home Assistant 2026.3.0 or newer
• ADAM Audio A-Series speaker on the same local network as your HA instance
• HACS (for the HACS install path)

Installation

Option A — HACS auto (recommended)

1. Open HACS → Integrations
2. Search for ADAM Audio Control
3. Click Download
4. Restart Home Assistant

Option B — HACS manual

1. Open HACS → Integrations → ⋮ → Custom repositories
2. Add https://github.com/Perhan35/hass-adam-audio-control as type Integration
3. Search for ADAM Audio, click Download
4. Restart Home Assistant

Option C — Fully manual

1. Copy the custom_components/adam_audio/ folder into your HA config directory:

   config/
   └── custom_components/
       └── adam_audio/    ← copy here
   

2. Restart Home Assistant

Adding the integration

Auto-discovery (recommended)

If your speakers are on the same network, HA will automatically detect them via mDNS:

1. Go to Settings → Devices & Services
2. A notification banner should appear: "New device discovered: ADAM Audio"
3. Click Configure and confirm each speaker

Manual entry

1. Settings → Devices & Services → + Add Integration
2. Search for ADAM Audio
3. Enter the speaker's IP address (assign a static DHCP lease to each speaker in your router for reliability)
4. Leave default port at 49494 unless you know it differs
5. Repeat for each speaker

Dashboard Cards

Some custom Lovelace cards are included. They are automatically registered as frontend resources when the integration loads — no manual resource setup needed.

Add a card

Edit your dashboard and at the bottom the custom Adam Audio cards will display. Select the one you want to add. Or add a Manual card with the following YAML (replace entity IDs with your own — find them in Settings → Devices & Services → your speaker).

On Home Assistant 2026.6 and later, picking any entity from a speaker (e.g. its mute switch) in the card picker also surfaces the ADAM Audio cards as suggestions in the Community section, pre-filled with the rest of that speaker's entities.

All cards use the same configuration schema, so you can switch between them by changing the type field.

Cards available

• custom:adam-audio-card
• custom:adam-audio-backplate-card
• custom:adam-audio-backplate-card-alt (coming soon)

ADAM Audio Card (custom:adam-audio-card)

A modern UI-style control card with segment selectors, sliders, and status indicators.

type: custom:adam-audio-card
title: Left Monitor
entities:
  mute:     switch.{entity_name}_mute
  sleep:    switch.{entity_name}_sleep
  input:    select.{entity_name}_input_source
  voicing:  select.{entity_name}_voicing
  bass:     number.{entity_name}_bass
  desk:     number.{entity_name}_desk
  presence: number.{entity_name}_presence
  treble:   number.{entity_name}_treble

ADAM Audio Backplate Card (custom:adam-audio-backplate-card)

A card that visually replicates the physical backplate of an ADAM Audio A-Series monitor — dark metallic panel, green LED indicators, frequency response curves, XLR/RCA connector graphics, and round hardware-style buttons.

• Room Adaptation: SVG EQ curves visualize the frequency bands. Green LEDs indicate the current dB value for each band. Click the round hardware buttons below each band (Bass, Desk, Presence, Treble) to cycle through values.
• Audio IN: XLR and RCA connector graphics with green LED indicators showing the active input. Click the "Input Select" hardware button to toggle between RCA and XLR.
• Voicing: Green LEDs for Pure, UNR, and Ext. Click the "Voicing" button to cycle through voicing modes.
• Mute / Sleep: Header buttons that highlight red (mute) or amber (sleep) when active.

type: custom:adam-audio-backplate-card
title: Left Monitor
entities:
  mute:     switch.left_mute
  sleep:    switch.left_sleep
  input:    select.left_input_source
  voicing:  select.left_voicing
  bass:     number.left_bass
  desk:     number.left_desk
  presence: number.left_presence
  treble:   number.left_treble

All Speakers Group (exemple with Backplate Card Alternative)

All cards work with the All Speakers group entities (prefixed all_speakers_):

type: custom:adam-audio-backplate-card-alt
title: All Monitors
entities:
  mute:     switch.all_speakers_mute
  sleep:    switch.all_speakers_sleep
  input:    select.all_speakers_input_source
  voicing:  select.all_speakers_voicing
  bass:     number.all_speakers_bass
  desk:     number.all_speakers_desk
  presence: number.all_speakers_presence
  treble:   number.all_speakers_treble

Finding your entity IDs: Go to Settings → Devices & Services → ADAM Audio → your device, then click on any entity to see its full ID.

Automations examples

# Mute both speakers when Sonos starts playing
automation:
  trigger:
    - platform: state
      entity_id: media_player.sonos
      to: playing
  action:
    - service: switch.turn_on
      target:
        entity_id: switch.all_speakers_mute

# Wake speakers at 9:00 AM on weekdays
automation:
  trigger:
    - platform: time
      at: "09:00:00"
  condition:
    - condition: time
      weekday: [mon, tue, wed, thu, fri]
  action:
    - service: switch.turn_off
      target:
        entity_id: switch.all_speakers_sleep

Protocol Library

The AES70/OCA protocol layer is published as a standalone Python package:

pip install pyadamaudiocontroller

This library (lib/pyadamaudiocontroller/) handles all low-level UDP communication with the speakers and has zero dependencies beyond the Python standard library. It is used by both the HACS custom component and the HA Core integration.

How it works

Communication uses the AES70/OCA protocol over UDP — the same protocol used by ADAM Audio's official A Control app. No audio data is sent over the network; this integration is control-only.

State is tracked optimistically: the integration records what it has set and assumes the speaker accepted it. There is no read-back for most parameters in the OCA implementation the speakers expose. This means if you change settings via the physical knob or the A Control app, HA won't know until you restart or reload the integration.

A keepalive is sent every 25 seconds to maintain the OCA session.

Troubleshooting

Warning: Avoid opening the official ADAM Audio A Control app while this integration is running. Although you can open it, doing so will cause the speakers to reset their active commands to the ones sent by A Control, overriding any state set by this integration.

Note: Commands can take a few seconds to take effect on the speakers. This is expected behavior.

Development & Testing

Repository Structure

This is a monorepo that produces three deliverables:

More info, see CONTRIBUTING.md#repository-structure.

TODO

• Add translation support
• Full test suite: Add tests for all entity platforms, group entity logic, and coordinator update cycle.
• Fix auto-discovery: zeroconf auto-discovery doesn't seem to work all the time
• Add support for more ADAM Audio speaker models: tested with A4V only
• Propose this integration to HACS
• Extract protocol library to PyPI (pyadamaudiocontroller)
• Propose this integration to Home Assistant Core: ongoing
• Enhance connectivity and error handling:
  • add retry logic,
  • implement a proper keepalive mechanism,
  • better error messages
