HomeKit to MQTT bridge 🏡📱

Depends on HAP-NodeJS by KhaosT, all credits belong to him.

This project follows the mqtt-smarthome architecture. I'm using this to control a multitude of MQTT-connected "Things" in my home automation through Siri and with HomeKit apps.

Prerequisites:

• Debian, Ubuntu, Raspbian or macOS
• Node.js 6 or higher
• If you're running on Linux, you'll need to make sure you have the libavahi-compat-libdnssd-dev package installed: sudo apt-get install libavahi-compat-libdnssd-dev

sudo npm install -g homekit2mqtt --unsafe-perm
homekit2mqtt -v debug

Usage: homekit2mqtt [options]

Options:
  -v, --verbosity   possible values: "error", "warn", "info", "debug"
                                                               [default: "info"]
  -m, --mapfile     JSON file containing HomeKit Services to MQTT mapping
                    definitions. See Readme.                           [default:
           "/usr/local/lib/node_modules/homekit2mqtt/example-homekit2mqtt.json"]
  -n, --name        instance name. used as mqtt client id and as prefix for
                    connected topic                         [default: "homekit"]
  -u, --url         mqtt broker url. See
                    https://github.com/mqttjs/MQTT.js#connect-using-a-url
                                                   [default: "mqtt://127.0.0.1"]
  -s, --storagedir  directory to store homekit data
  -h, --help        Show help                                          [boolean]
  --version         Show version number                                [boolean]
  -c, --pincode                                          [default: "031-45-154"]
  -a, --username                                  [default: "CC:22:3D:E3:CE:F6"]
  -b, --bridgename                                      [default: "MQTT Bridge"]
  -p, --port                                                    [default: 51826]
                                            
                                                                 

You have to create a JSON file that defines devices and mappings from MQTT-topics and payloads to HomeKit-characteristics.

See example-homekit2mqtt.json.

Every Accessory is represented like this in the JSON file:

  "TemperatureSensor": {                                    // Unique Name - used to generate the accessory UUID
    "service": "TemperatureSensor",                         // HomeKit Service Type (see below)
    "name": "TemperatureSensor",                            // Display Name
    "topic": {                                              
        // ... MQTT Topic Configuration ...
    },
    "payload": {
        // ... MQTT Payload Configuration ...
    },
    "manufacturer": "Generic",                              // Additional Accessory Infos (optional)
    "model": "TemperatureSensor"                            // Additional Accessory Infos (optional)
  }
