     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)
