Hi this one looks really nice! It would be so nice of you if you could post or send me some more instructions how you did it such as diagram.
Best regards

These are the connections between IKEAs Zigbee controller and Raspberry Pi GPIOs:
COLOR FUNC GPIO PIN WiringPi
RT VCC 3.3V 1 –
SW GND GND 39 –
GR RESET GPIO2 3 8
GE COLOR GPIO3 5 9
WS DIM+ GPIO26 37 25
OR ON/OFF GPIO19 35 24
BR DIM- GPIO13 33 23
Then you use WiringPi to control the GPIOs, e.g. to DIM+
gpio toggle 25 //toggles from 1 to 0
Delay 50
gpio toggle 25 //toggles from 0 to 1
Delay 50
