I have tried two brands of open/close sensors with the Ezlo hub. The one I am currently using is the Aeotec Door/Window Sensor 7 Pro.
I am able to add the sensor just fine to the hub, and for awhile, the hub shows its open/closed status as I move the magnet to, or away from the sensor.
However, after awhile, the hub stops responding to the sensor events. Meaning, the Vera UI no longer detects/shows a change, AND the hub no longer broadcasts a change event.
I’ve removed, and re-added the devices to the hub, same issue.
