Homebridge not showing up in home.app
Hi there,

I'm not able to add homebridge in the apple home app : it does not appears at all. So far I'm using a pretty standard setup, running on a Synology NAS (with DSM 6.1.7-15284 Update 1). Here is my config files :

package.json:
```
{
  "dependencies": {
    "homebridge-dummy": "^0.2.0"
  }
}
```

config.json:
```
{
    "bridge": {
        "name": "Homebridge",
        "username": "CC:22:3D:E3:CE:30",
        "port": 51826,
        "pin": "031-45-154"
    },

    "description": "This is an example configuration file.",

    "accessories": [
    	{
          "accessory": "DummySwitch",
          "name": "My Switch",
          "stateful": true
        }  
    ],

    "platforms": [
    ]
}
```
DSM_HOSTNAME environment variable is tuned correctly.

Nothing strange in log files so far. Using a bonjour browser on my iPhone does not show any homekit capabilities from my NAS IP ... 

I have no idea on how to debug this. Do you have some suggestions? Thanks.
