I have one or two that seem to flip true state open vs closed. Fresh batteries in all.
One sensor seemed to improve only with getting the magnet very close to the sensor.
I'm using only two Cree bulbs as repeaters, one at one end of the house on the main floor, the other near the opposite end in the basement ceiling. The office is on the 2nd floor, mid house location.
Maybe I need a few of those outlets?
If it helps, here's my zigbee routing:
