@natec007 - This is fantastic. Can’t wait to back your project on Kickstarter!
What ZigBee radio IC are you using, and is it a module with integrated RF circuit, or are you designing the antenna yourself? Any thoughts on the FCC certification process (if needed)? Are you going to have to purchase a OUI from the IEEE Registration Authority? I am asking because those are the things that I am still unclear about with my own project.
