Homebridge stops after config.json update
Hi

The plugin seems to not work at all on my homebridge. Could very well be my fault, but still I hope someone here might be able to help. 

The issue is when I update the config.json with the following:

```
{
    "bridge": {
        "name": "Homebridge",
        "username": "CC:22:3D:E3:CE:30",
        "port": 51826,
        "pin": "123-45-568"
    },

"platforms": [
        {
            "platform": "XiaoMiAcPartner",
            "devices":{
                "<myip>":"my-token",
            }],

"accessories":[
                  {
                    "name": "Ac Partner",
                    "type": "climate"
                  }
            ]
}
```
After I make the change, homebridge stops running. 

Not sure what I am doing wrong

Thanks
