Sorry, I should have been more precise: you may need the latest hue snapshot binding (or the one from the milestone)
Sure: delete the binding in PaperUI, download the hue binding snapshot jar, put it in your addons folder.
You may need to restart openHAB or even clear tmp and cache folders to make it work.
Also you may need to manually install esh-io-transport-upnp:
I have a problem with the motion sensor, too. I first use the 2.4 hue binding (Openhab is 2.4) and saw all relevant things (light sensor as well). Temperatur and Motion are working correct but the light sensor give me always 0 as light level. I checked it under the web interface: http://bridge IP/api/UserName/sensors.
When I saw this thread I tried it out and deinstalled the binding and installed 2.5 snapshot, removed bridge and added it as thing again. But the light level is still 0. I have two Motion sensors but both show the same behavior. Im very thankful for any hint.
Thank you for your answer and sorry for my late answer. I followed your description and was disappointed that it doesn’t work, first. But a day later one light sensor works and some days later the second sensor works, as well. This delays are a bit strange but it works now, thank you for your help.
