Showing up as contact sensor in the Home app
Thanks for the plugin, however I've run into 2 issues.

When running Homebridge through 'sudo systemctl start homebridge', it does not show the device in the Home app.
If I just run 'homebridge', it adds an extra device and I can see it start/stop scanning, ie:

start new round of scan
[2018-12-20 10:22:55] [Temperate & Humidity] Stopped scanning.
[2018-12-20 10:22:57] [Temperate & Humidity] Start scanning.

However, the device it adds in the Home app shows up as a contact sensor 'ContactSensor_ContactSensor_feaa' ?

Not really sure where to go from here?
Here's my config file:

```
{
  "bridge": {
    "name": "Homebridge",
    "username": "CC:22:3D:E3:CE:31",
    "port": 51826,
    "pin": "031-45-154"
  },
  "description": "HomeBridge RPI",

 "accessories": [
     {
       "accessory": "Hygrotermograph",
       "name": "Temperate & Humidity",
       "timeout": 15,
       "temperatureName": "Temperature",
       "humidityName": "Humidity",
       "fakeGatoEnabled": false
     }
 ],

 
  "platforms": [
     {
       "platform": "MiAqaraPlatform",
       "gateways": {
         "7811dcb7df05": "71D0E9E78A2E4A07"
       }
     },
        {
            "platform" : "yeelight",
            "name" : "yeelight"
        }
   ]
}
```

Any help is much appreciated. Thanks!
