The door sensors have, unlike the Window Sensors not tilt mode (display of the tilted state), but it should provide a break-in protection based on vibrations.
The Teaching the sensors on the system is also very simple as in the other sensors. At one meter only the link buttons on the sensor and the base must be pressed until the sensor has been detected. Then an update, the sensor Teach (opening and closing the door) and you're done. The sensor is clamped on a holding plate, which is glued to the door. This makes it the case that he should be re-trained at the base to bring problems back in the 1 meter distance from the base.
The status message on the respective doors (balcony door and self-locking aluminum entrance door) works well, the unlocking / locking itself is not reported by the sensor, but only the pure opening and closing. As our front door must be closed rather strengthens to activate the Selbstverrieglung, I had only doubts whether this triggers the vibration alert, he does not. Generally, this alarm is not triggered even with vigorous slamming of the door. Also banging on the closed door led to no alarm.
I therefore believe that the alarm function of the sensor unnecessary. In a slump would probably not have the necessary force expended on the door to activate the sensor. It makes sense, in my view here rather to monitor the interior with the motion sensors so that an intrusion is detected by this.
Regarding the status messages of the doors of the sensor but works quite reliably. In recent weeks, he has not yet forgotten the state and did not have to be trained again, here Gigaset seems to have improved. In conjunction with the motion sensors can also report a homecoming of trusting people, when the corresponding mode in element is activated. Whether you need this, everyone must decide for themselves.
Also I think the sensor for pure condition monitoring too expensive and bought it only addition since the closing of the door was ever forgotten what app is now seen in the Gigaset. Equips you all the windows and doors of a house with the Window and Door sensors from one is almost in the price region of semiprofessional alarm. The advertised burglar alarm, I think at this sensor for little use and thus Door is not necessary if you do not necessarily monitor the status of doors or a Homecoming want to get reported.
Update:
I had to teach the new sensors due to a self-inflicted reset the base. When removing from the holder actually triggered the vibration alert. The sensor is a high sound, the not too loud, however. Abschrenkend should not be and is not compared to Siren, which are an extension of the set a really uncomfortable loud sound. After renewed Teach at the base I could infect the way the sensor and re-arrange arbitrarily, without that the alarm was triggered. I maintain a burglary protection, these sensors in my eyes rather less.
