[homebridge-myq] This plugin generated a warning from the characteristic 'Model'
**Describe The Problem:**
Although not a functional issue, the log file is filled with warning messages about the characteristic 'Model', as per the log snapshot. This makes it challenging to diagnose other issues, e.g., with other plug-ins, due to unwarranted noise in the log. 

**To Reproduce:**
Configure required settings, leaving optional settings as default, i.e., empty. 

**Logs:**
Snapshot from log:
```
[homebridge-myq] This plugin generated a warning from the characteristic 'Model': [Model] characteristic must have a length of more than 1 character otherwise HomeKit will reject this accessory, ignoring new value. See https://git.io/JtMGR for more info.
```
