Testing the PIR Sensor Functionality

After creating all three automations, the PIR sensor functionality should be tested.

For easier testing and diagnostics, it is recommended to mark all participating KNX group objects with a common tag, for example pir. This allows filtering all relevant objects in the Objects tab of the Configurator.

In your controller, open Configurator > Objects and filter the object list using the selected tag. This view displays all input and output objects involved in the PIR control logic.

In this view, you can manually set values of input objects, for example to simulate PIR sensor activation or toggle button operation. Changes to output objects are displayed in real time.

Functional Overview

The behavior of this example should be as follows:

When the PIR sensor is triggered (input object 31/1/4 PIR toccata – Occupancy input is set to true), the light is switched ON:
- to high level (100 %) if the current time is between 06:00 and 20:00,
- otherwise to low level (25 %).
If no occupancy is detected and the PIR timer expires, the light is switched OFF.
If the toggle button is pressed (input object 32/1/22 PB 22 is set to true), the light is switched ON independently of the PIR sensor state. The scene PIR high or PIR low is selected according to the current time.
The light remains ON until the toggle button is pressed again (input object is set to false).

Possible Improvement

The group object 32/1/22 PB 22 can also be used in an Output device / Binary output connected to an LED in the push button. This provides visual feedback about the current state of the toggle button.
