I do not think you do fully realize what that N in NFC stands for. It is near as in 'centimeters'. I would not be surprised if someone cranked that up to miles by using a radio telescope at the other end of the connection and averaging signals over months, but I doubt you can get meters of range through walls in a package that fits inside your house.
Zigbee probably is the best bet for a wireless technology to use here.
