Thanks Tom. I have already taken a look at the docs. What i actually want to know is if there's a possibility of adding some other sensor to my 13192-SARDs, apart from the on-board X,Y&Z accelerometers.
I'd start with the Freescale Zigbee product page, located here. There are links to documentation, data sheets, and development kits. This is a probably a good starting place to track down exactly what you want.
