HS110 power consumption no showing
Hi guys, 

I don't know if it is me that not configuring the plugin correctly, but my Eve App doesn't shows power consumption of my HS110 plug. I can see that the plugin is correctly getting informations on the Homebridge console instead. 
This is my configuration for my plug in the config file: 

```json 
{
            "platform": "TplinkSmarthome",
            "name": "PLUGS",
            "broadcast": "255.255.255.255",
            "devices": [],
            "deviceTypes": [],
            "macAddresses": [],
            "excludeMacAddresses": [],
            "pollingInterval": 1,
            "addCustomCharacteristics": true,
            "inUseThreshold": 0,
            "switchModels": [
                "HS110"
            ],
            "timeout": 15
        }
```
If you could help me, I bought this device especially for power consumption.. bad luck if it is not shown on the app. 
Thanks
