Installation

npm install -g homebridge-kef-lsx

Or search for "KEF" in the Homebridge UI.

Configuration

The plugin auto-discovers KEF speakers on your network. No configuration is required.

Optional settings in config.json:

{
  "platforms": [
    {
      "platform": "KEFSpeaker",
      "autodiscover": true,
      "pollingInterval": 5000,
      "speakers": [
        {
          "name": "Living Room",
          "ip": "192.168.1.100"
        }
      ]
    }
  ]
}

| Option | Default | Description | |--------|---------|-------------| | autodiscover | true | Automatically find speakers via mDNS | | pollingInterval | 5000 | How often to sync state (ms) | | speakers | [] | Manual speaker config (optional fallback) |

HomeKit Devices

Each speaker appears as two accessories:

1. TV - Shows power state, tap to select input source
2. Lightbulb - Volume control (brightness = volume, on/off = mute)

NFC Quick Switch (Bonus)

Want to tap your phone to switch to Bluetooth? Create an Apple Shortcut:

1. Shortcuts app → New Shortcut → "Get Contents of URL"
2. URL: http://<speaker-ip>/api/setData
3. Method: POST
4. Headers: Content-Type: application/json
5. Body:

{
  "path": "settings:/kef/play/physicalSource",
  "role": "value",
  "value": {
    "type": "kefPhysicalSource",
    "kefPhysicalSource": "bluetooth"
  }
}

Then create an NFC automation to run this shortcut when you tap a tag.
