Running as root
I'm trying to run homebridge-amazondash. It requires homebridge to be run as root to work, so I cannot get it to work with this docker image. Any thoughts on how to get this one working?

I'm getting the following in my log. I tried looking for alternative plugins but they all require root.
```
