4. Install Audio Control

Download it from HACS

1. Click HACS in the Home Assistant sidebar.
2. Search for Audio Control and open it.
3. Click Download, then Download again to confirm.
4. Restart Home Assistant: Settings → System → ⏻ (top right) → Restart Home Assistant.

Or click this button to jump straight to it:

Add your amplifier

1. Go to Settings, then Devices & services.

   

2. Click Add integration (bottom right), type Audio Control, and click it.

   

3. Fill in the form:

   

   • Device — choose your amplifier's model from the list.
   • Connection — the USB adapter. Home Assistant usually lists it for you under Detected locally; it looks like /dev/serial/by-id/usb-FTDI_.... How to find it.

4. Click Submit.

That's it — each zone now appears in Home Assistant. Next, give them proper names: Names & settings.

Try it without the amplifier

Type demo in Connection to get a pretend amplifier. Everything works the same, so you can set up your dashboard first. Switch to the real connection later (how).

Finding the connection

Go to Settings → Connectivity → Serial. It lists the USB adapters Home Assistant can see. Copy the one that starts with /dev/serial/by-id/.

(Older Home Assistant versions: Settings → System → Hardware → ⋮ → All hardware, then search for "serial".)
