Home Assistant integration for controlling Audac audio devices:
- MTX48 / MTX88 – Audio matrix (zone control)
- XMP44 – Modular audio system (SourceCon modules)
Communicates directly via TCP with the devices and ships with Bubble Card-inspired Lovelace cards.
- Direct TCP connection – Communicates directly with Audac devices (port 5001)
- Media player entities – Each zone is exposed as its own media player
- Zone control – Volume, mute, and source selection per zone
- Zone coupling – Link zones as master/slave (dropdown in options). Slave zones are automatically synchronized and hidden from the card. Linked zone names are shown next to the link icon

- Accent color – Freely configurable accent color in the card editor
- Accordion navigation – Only one zone expanded at a time
- Bubble Card design – Rounded corners, smooth gradients, fluid animations
- Card editor – Visual configuration directly in the Lovelace editor
- Auto-reconnect – Exponential backoff on connection loss (max 30 s)
