So i am pretty sure somewhere along the line between the OPEN and CLOSED states the sensor is also reading a null state from somewhere. when done as a contact, and following along on the mqtt mosquitto server (using mqtt.fx) i can see when the sensor sees motion it posts a 1, when the time expires, it posts a 0, and the Contact icon changes along with it.

i would actually not have noticed this issue if i didnt check the openhab.log to make sure it all looked good, but now i cant seem to be able to stop the issue. Any ideas here?
