DALI-2 standards allow for devices to now contain instances. Instances are input devices (sensor, switches, etc) that share the same short address as the parent device.
4 Button switch panel can have one short address but with 4 (switch) instances.
The zencontrol PIR sensors consists of two instances, PIR and Lux level sensor sharing the same short address.
Instances can be configured with scene validity which allows the input device to work only when the target is in specific scenes. By default it is configured so that the device is enabled for all scenes. This can be changed so that it can work in a particular scene or multiples scenes.
Each instance application in the grid view has a scene column which when opened will display a checkbox for each scene as well as buttons to clear all checkboxes and select all checkboxes. This allows you to pick which scenes the input device will be enabled in.
