Home Automation Project

Hi,

As my final project at college, I want to develop an Android app that controls two xbee modules for home automation purposes, I think I need a ethernet shield Aldo...

I only need some help with the project idea, what I want to do is use the app to send information to the ethernet shield via internet, and then the Arduíno receive those commands from the app and can switch relays and etc via xbee, is that possible? Anyone hás any material to help?

Thanks in advance!
