 Movement Meta Event Injector:
     movement sensor (maybe threshold number movements within 5 minutes) -> Movement Passed Threshold
     no movement within 3 hours and movement within the last 6 hours -> Movement Absence Passed Threshold
+    asign confidence to metaevent
+    -> if few movement was detected before door closed -> lower timeout until no presence !
+    -> if a lot of movement was detected -> longer timeout until no presence
+    (e.g. confidence of SomethingReallyIsMoving{false} must reach level of SomethingReallyIsMoving{true} before presence switch is triggered

 Sensor Spike Event Injector:
     monitors sensor values and calculates running average mean, stddev over last hours,
     raises Event is value spikes, aka rised beyond mean +- stddev within 2 min (enables after 1 hour of collecting data)
   
+
+
+Use Cases to detect:
+* someone walks by the movement sensor towards the door. Closes it from outside with the Card and leaves -> nobody in room anymore
+* somone still works in the OLGA room while the last person in the main room leaves and closes the door behind him with the card
+
+-> best idea so far:
+ -> all doors closed and shut -> no movement for ~30 seconds after closing doors -> assume everybody left
+                                               -> movement within next ~30 seconds -> assume somebody is still here until SomthingReallyIsMoving{false} fires

+possible better Solution:
+  close door "differently" from outside if people are still inside (e.g. with buttonpress prior to closing with card from outside... or install a "CLOSE ONLY" event sending device which can be triggered through the glass)
