Where you'd use it
Tilt-and-turn ventilation logic
Mount on a tilt-and-turn window so the sensor's tilt angle measurement tells your automation the difference between 'cracked for airflow' and 'fully open', only pausing heating for the latter.
Alerts on rarely-used entry points
Fit to a side door or utility entrance to get an instant notification if it's opened, using the Zigbee link where BLE range alone wouldn't reach reliably.
Arrival lighting after dark
Combine the open/close detection with the built-in light sensor so the hallway light comes on automatically when you come through the front door after dusk.
