Since it only has 4 controles it was easy to grab the IR codes with a IR reader made on a breadboard and an Arduino. For the IR receiver i just desoldered the IR receiver element. After reading the codes i extended the wires and attached the LED strip underneath the wall board of the stairs. I added two mini PIR sensors for movement detection and wired all to an Arduino for control. I just kept it simple and added a IR LED to the Arduino that it bound together with the IR receiver element to control the whole thing.
The LED strip has also a dim function and that will make it possible to fade-in and fade-out the light.
