Loading 0 accessories
I have a similar issue like this one https://github.com/plasticrake/homebridge-tplink-smarthome/issues/47

When loading homebridge, the platform load fine, but it could not find my lightbulbs:
```
[2019-1-26 01:21:43] [TplinkSmarthome] Initializing TplinkSmarthome platform...
[2019-1-26 01:21:43] [TplinkSmarthome] homebridge-tplink-smarthome v3.11.0, node v8.11.3, homebridge v0.4.44
[2019-1-26 01:21:43] Loading 0 accessories...
```

I also tried to run `tplink-smarthome-api search` and got no output only:
```
$ tplink-smarthome-api search
Searching...
startDiscovery({ discoveryInterval: 2000,
  discoveryTimeout: 10000,
  breakoutChildren: false })
```

here's my config:
```

        "bridge": {
                "name": "Homebridge",
                "username": "CC:22:3D:E3:CE:30",

        },

                                {

                                },
                                {
                                        "host": "192.168.0.210"
                                }],
