Unfortunately, now everything returns because the whole system is too unreliable.
For Door Sensor:
From my perspective, the sensors "Window" and "Motion" really meaningful only.
Although the "Door Sensor" reports in connection with "Motion" a decent "Homecoming" and also reports a hard shake at the door as "alarm". But first, I think the distinction between "Homecoming" (only the door, then the movement in the corridor) and the simple motion detection and / or door opening unnecessary. Secondly, a burglar will rarely occur with brute force the door. He cracks also the castle's anyway not "Door" alarm. Then better like the Door, Windows or Motion Sensor to alert and / or the siren off (Holiday mode). Door also reports no tipping. And the wind, or the neighbor's child skin the door to a false alarm there.
The "Window sensor" on the other hand works reasonably reliably. Also clearly preferable to patio doors to the Door Sensor (false alarms, tilt so) ... But sliding doors can thus be actually not saved. Also slow tilting movements are sometimes not recognized.
The "Motion Sensor" works perfectly and reliably - especially also because it ignores our cat and paused to avoid about 20 seconds mass messages after each location.
Summary: As usable as intrusion sensor hardly need the "Door Sensor" only when one event "Homecoming" (ie the coincidence of events "door was open" + "door was shorted then" + timely motion detection in the hallway necessarily a special push message wishes by "Motion") as such on the mobile phone. So I would always advise to further expand the "Windows" sensors because they are more flexible use
Addendum: Which sensor Anyway: The entire system is too unreliable - unfortunately now all return.
