Where you'd use it
Door and Window Entry Alerts
Fit the BLU Door/Window Black to a side door or ground-floor window so an unexpected opening triggers an instant notification or automation scene.
Tilt-Window Ventilation Checks
Use the tilt angle measurement on a tilt-and-turn window to tell whether it's been left ajar for ventilation rather than fully opened, so security automations don't misfire.
Light-Aware Curtain Triggers
Combine the built-in luminosity reading with the open/close state to trigger blinds or lights automatically when a window is opened in a dark room.
