This logic group sends a message via PushBullet when
- No one is at home (input "Present/Absent" value "One")
AND
- one of the windows is opened (input "Status window" value "one")
AND
- The release of the http request element is given (week clock output value "one" - from 10:30 pm to 6 am).

Thus, the messages are reduced and only one message is sent if all conditions are fulfilled.
