[SOLVED] Tradfri bulbs offline


I am new and using PaperUI / Windows. Added Tadfri binding and gateway is online. However when searching for Tadfri bindings in the inbox nothing appears. So I added manually and tried some code according to the manual : 0100. also others like around 30-45 (suggested in other conversations)

Bulbs stays offline. I tried another bulb but same story.
What am I doing wrong here ?



SOLVED. I thought for linking with openhab no Ikea remote was needed. Bought remote and is now working fine.
