Use Case 2 – Presence monitoring with movement detector – Luxury hotel room
Instead of a key card holder, the motion detector mini basic together with a KNX power supply with IP interface takes over the presence detection. The power supply is operated by the communication objects of the KNX push-button interface 4-gang Secure. This can be used to trigger light scenes and operating modes (e.g. air conditioning, underfloor heating, etc.) in hotel rooms, for example:
A. Light scene 1: with 50 % light in the bathroom, 100 % light at the bed; operating mode 1: "Comfort"
B. Light scene 2: "All Off"; operating mode 2: "Eco".
In addition to the hotel room, further applications are also possible in offices, conference rooms, public washrooms as well as corridors and passages.

When a person enters the room for the first time (First Entry - door contact is activated), a "Welcome" scene is triggered. The lighting is switched on dimmed (additional dimming actuator required).
If the presence detector detects presence within the activation time, the "Comfort" operating mode is activated, the blind is moved to its upper end position (this requires an additional blinds actuator) and additional lighting is dimmed.
A different scene is also triggered if the presence detector does not detect presence within the activation time: the lighting is switched off ("All Off").
A "Night Light" scene is triggered when another person enters the room (door contact is activated again): the entrance lighting is dimmed to minimum brightness.
If a person leaves the room and no more presence is detected after a delay time, an operating mode is transmitted. The operating mode "Standby" can be activated in this way, for example. A "Goodbye" scene is triggered after the activation time, thus switching off the lighting.

PRESENCE MODE |
|
The presence mode describes the state when a door contact is detected, although there is presence in the room. |
|
If trigger 1 is activated again and no presence is detected within a configurable time period, the lighting is deactivated and the room controller switches to "Comfort" or "Standby" mode. |
|
If a presence is detected, "Goodbye" will be aborted. Trigger 1 must be activated again to start the "Goodbye" loop again. |
