Remote temperature and humidity sensor (Sodaq) - Receiver Help

i working on building remote temperature , humidity sensor displays data locally on oled screen , transmits wirelessly, via xbee, arduino oled via xbee.

i able display data locally, not sure how code receiver.

(i have set xbee's in @ mode , 1 coordinator , other router. can send "hello world!", extent of able do...)

your , guidance appreciated! 

below parts list , transmitter code (which resides on transmitter arduino).

2- sodaq kits
