I got an issue with door sensor, it works fine when item type is string, when door open/close, I can see it on habpanel it’s status, but if I set it as CONTACT, it couldn’t change from OPEN to CLOSE, It only change from NULL/CLOSE to OPEN.
Please tell me why, in http://docs.openhab.org/concepts/items.html, it should suit with it.
I got error below
