The interface is now hooked up! I also got data logging working for humidity & temperature - something I was not expecting to get done by the Aug 20th deadline. I also rewrote large parts of the node.js app to make it way more reliable.

I did some simple range tests & am very impressed. With the spoke at one end of my house and the hub at the other, there are very few packets that fail - meanwhile, my wifi signal struggles to reach that far.
