What it’s for

  • Security: a phone alert or a siren when a door opens while nobody is home.
  • Saving heat: Home Assistant switches off the heating or A/C when a window is open.
  • Convenience: the hallway or pantry light turns on as soon as you open the door.

How to choose

All sensors that detect opening are also in the filter Sensor → Door/window opening in the Sensors category.
