Where you'd use it
Entry point alerting
Fit it to a side gate or back door and get an instant notification if it's opened while you're out, without needing a wired contact or hub-based sensor.
Heating pause on open window
Pair it with a smart radiator valve or heating zone so the system automatically pauses when a window is opened, cutting the obvious waste of heating an empty room with the window ajar.
Tilt-and-turn window position
On a tilt-and-turn window, use the tilt angle measurement to distinguish between 'cracked open for ventilation' and 'fully open', so automations can respond differently to each state.
