Openthread border router support

Configuration
37

Has anything changed here? I’m trying the set-up mentioned here:

I’ve got the latest official otbr image working: When adding the otbr integration it seems to connect to http://[ip]:8081. I also activated the Thread integration and the /node/dataset/active endpoint returns:

// 20240208082610
// http://192.168.1.6:8081/node/dataset/active

{
  "ActiveTimestamp": {
    "Seconds": 1,
    "Ticks": 0,
    "Authoritative": false
  },
  "NetworkKey": "E18B36ECBA28F4A2666CDFD18B944E24",
  "NetworkName": "home-assistant",
  "ExtPanId": "47BDCE848AF31219",
  "MeshLocalPrefix": "fd12:7168:b07:8092::/64",
  "PanId": 2900,
  "Channel": 15,
  "PSKc": "AD98CEE09E2F1207608C9E25E832CD57",
  "SecurityPolicy": {
    "RotationTime": 672,
    "ObtainNetworkKey": true,
    "NativeCommissioning": true,
    "Routers": true,
    "ExternalCommissioning": true,
    "CommercialCommissioning": false,
    "AutonomousEnrollment": false,
    "NetworkKeyProvisioning": false,
    "TobleLink": true,
    "NonCcmRouters": false
  },
  "ChannelMask": 134215680
}

And the Thread integration shows my home-assistant network with a borderrouter called BorderRouter. But this border router disappears after a couple of minutes (seemingly randomly).

Any clue why this might happen?
