We have prepared a User Guide on how to work with Elelabs ZigBee USB with OpenHAB.
Does the USB version work on a RPi based openHab ?
Yes. It does.
Does it work with all zigbee profiles ?
The adapter itself can work with ZHA, ZLL, Energy measurement profiles, but to my understanding ZigBee OpenHAB binding supports only ZHA profile right now. Though it can still work with the ZLL devices, just doesn’t support all the features, ZLL offers.
Does it work with HUE ?
Yes. It does. At least tested with the bulbs. More devices are on the test list.
Does it work with IKEA lamp motion and switches devices ?
Lamp yes, motion and switches to be tested.
I read posts that are indicating (for other zibee USB devices) the commutation stops after x hours and openhab has to be restarted to get it working again. Its this device not having this issue ?
Have not seen yet. Would appreciate a link to the problem description to get a deep look.
what version of openhab did you use ?
The required support for Elelabs USB Adapter was added since 2.3.0 ZigBee binding version. So 2.3.0+
