The Homebridge Raspberry Pi image is just Raspbian Linux with Homebridge installed as a service.
If you are facing an issue that is not Homebridge related you should look elsewhere for support.

**Describe The Bug:**
The README declares the user should visit http://my-device-ip or http://homebridge.local to reach the running unit and neglects to provide the port number

**To Reproduce:**
Flash new image, connect rpi to ethernet, boot rpi, wait 5-10min and realize you cannot connect to the provided url. You can only connect when the 8581 port is provided in the url.
