TCP Timeout after 15000ms - "emeter":{"get_realtime"
deleted home bridge by accident, but also switched home bridge to a new router. 
moved to DSM 7 on Synology NAS that runs home bridge and now getting a number of these errors from various things. Noticed it when I was looking at my router settings as I switched from AC to AX router, but ended up going back to old router, still seeing issues. I assume this might be a DSM 7 issue with the DSM 6 home bridge 1.x copied to home bridge for synology 2.0. 

### Expected Behavior
not to throw codes, and cause home bridge restarts
### Current Behavior
Throws tons of these codes
### Steps to Reproduce (for bugs)
<!-- Please add a series of steps to reproduce the problem. -->

### Versions
<!-- Please run commands and include versions below. -->
- **Node**:       `node --version`
- **Homebridge**: `homebridge --version`
- **OS**:         <!-- The version and architecture of your operating system -->

### Configuration
{
    "name": "TplinkSmarthome",
    "addCustomCharacteristics": true,
    "deviceTypes": [
        "plug",
        "bulb"
    ],
    "platform": "TplinkSmarthome"
}

```
