For us to better assist you, please use code fences and other principles found here

If you are new to openHAB try installing the stable version first (2.2). You’ll have less changes of anything going wrong. Once you gain experience the start playing around with the SNAPSHOTS.

thank for information, I will use the requirement template in later post

thanks Vincent, I install 2.2, works.
