I found a workaround on youtube: OpenHab Tutorial 5.1 (Deutsch) Philips Hue
- Take your browser, open
<your-huebrige-ip>/debug/clip.html
- The Clip API Debugger opens.
- Enter
/api
in the url field - Enter
{"devicetype":"openhabhuebinding#openhab"}
- Press the pairing button on the bridge, then press “POST” in the debugger
A JSON answer will appear, containing the cryptic user name value. - Now take the username and enter it in the hue bridge configuration in PaperUI.
This will bring the bridge online in OpenHAB.
Hope this helps someone,
