hassio not seeing newly installed system

All, 

I just got my  system in the mail.  Hooked it up and configured the wifi.  I added the "konnected" section in the configuration.yml with the last 6 digits of the mac address and restarted hassio which is running on a PI3.

I don't get any errors in the home_assistant.log and I configured ngix, and am able to connected without https.  

Should I expect to see the devices themselves in home page or do I actually need to hook sensor in before I see anything?  Wanted to make sure hassio sees everything before moving forward.
