Window, door contacts and motion sensors
When planning the SmartHome, the integration of various sensors was on my list right from the start. They can be used not only to secure and protect the building from intruders but also for future presence detection.
Window and door contacts
Here, I decided for a solution with integrated window and door contacts, which are connected via simple KNX universal interfaces. Each time they open or close, they send a message which is available in openHAB and can be further processed with its own rules.
In addition, there are in house KNX motion sensors which also send messages that can be further processed by their own rules.
Rules and more
All this data are immediately sent via push notification to my mobile phone.
Furthermore, I had also experimented with conventional motion detectors. However, these did not prove to be so exact and were therefore replaced by the KNX variant.
