two recommendations:
- instead of the stock Edge drivers, try community developed Edge drivers such as https://community.smartthings.com/t/edge-driver-mc-zigbee-drivers-for-motion-open-close-moisture-smoke-co-sensors-and-others-devices/231689
- if still experiencing issues… power off your hub for 30 minutes which will cause the zigbee network mesh to go into panic mode and rebuild when hub is powered back up or something to that effect.
