Z-wave repair is not going to help in this case since most of his sensors are zigbee but sounded like a range issue. Try power off your hub for about 20 minutes with batteries removed. That will help repairing your zigbee mesh. To be sure it’s a range issue. Also move the sensors closer to the hub for testing or relocate your hub to a different location if the power off didn’t help.
It doesn’t take too much for the vibration sensor but it should not report as OPEN, instead it will say something like it was ACTIVE. I’m beginning to think there might be something wrong with your hub. Another possibility might be WiFi interference which can sometimes be problematic if the hub is too close to your router or your WiFi channel overlaps ZigBee channel. Read this article:
my router and hub are next to each other, may be that might be an issue, i will move my hub to other location and see if that helps. or i will change my WIFI channel to 1 or 6 as it does not overlap with zigbee n/w
I’m not sure what else to suggest. The only other thing is that the sensors may be faulty or something is interfering with the signal to them. Try taking them off the window/door and test them right near the hub.
one part of sensor is little low to the magnet. i added some extra stickers back and made it equal to magnet part, hope this might be the issue. but i wonder why it worked all these days and caused issues since 2 weeks with out any changes,
