Out pins 9 + flow
  • flow v15.0.0
  • device object v15.0.0

    The full device: id, name, room, type, capabilities, current state.

  • device id value v15.0.0

    Stable platform id, e.g. zigbee:0x00158d0007e1a2b3.

  • name value v15.0.0

    The device's friendly name.

  • capability value v15.0.0

    Which capability changed, e.g. occupancy, contact, power.

  • value value v15.0.0

    The new value.

  • previous value v15.0.0

    The value before this change, empty on the first report.

  • at number v15.0.0

    Unix seconds the device reported.

Start-of-flow trigger for occupancy specifically. Equivalent to sensor activated with sensor_type=occupancy, and exists because it is the single most common automation. Fires on the false->true transition.

The most common automation there is. presence detected fires on the false to true transition of occupancy in the hallway, so somebody standing still does not re-run it. Its device id feeds get device state, which reads the illuminance the same sensor reports; < compares that against 30 lux and branch only lets light on run when the room is actually dark.

Studio canvas example for the presence detected block: motion, but only after dark.
