Where you'd use it
Arrival Lighting
Fit one to the front door so the moment it's opened your hallway lights and heating scene switch on automatically, with no need to reach for a switch.
Tilt-Window Ventilation Check
Mount it on a tilt-and-turn window to distinguish between fully open and vent-tilted positions, so heating can pause only when the window is properly open rather than just cracked.
Unattended Room Alerts
Get a push notification if a shed, garage or spare room door opens while you're out, using the built-in light sensor to also flag if a light's been left on inside.
