If you are not on OH2.2, then you have an old version of the binding, which could explain why you are having issues. If you are on OH2.2, you have a pretty recent version of the Zigbee binding. But it is still very much in development, so I suggest you start using the 2.3 snapshot version of the binding. For a lot of good info and to learn about new functionality when it is added, you can find out about it in this thread…
