Case 3 - mixed configuration¶

Having Thread network configured and operational, you can start KNX IoT device configuration and testing. One device must be configured as an Actuator and one as a Sensor.

Perform configuration/mapping of buttons built in to KNX IoT sensor to control LEDs built in to the KNX IoT Actuator - one button to multiple LEDs. It is achieved by setting KNX Actuator nRF52840 DK to receive events from multple groups.

Configure Actuator device by adding entries to Actuator’s Group Object Table.

uart:~$ knx got add 1 /p/1 22 [1,2,3,4]
uart:~$ knx got add 2 /p/2 22 [2,3,4]
uart:~$ knx got add 3 /p/3 22 [3,4]
uart:~$ knx got add 4 /p/4 22 [4]

Set a device installation identifier and a device individual address for the Actuator device.
```
uart:~$ knx dev iid 1
uart:~$ knx dev ia 1
```

Configure Sensor device by adding entries to Sensor’s Group Object Table.

uart:~$ knx got add 1 /p/1 22 [1]
uart:~$ knx got add 2 /p/2 22 [2]
uart:~$ knx got add 3 /p/3 22 [3]
uart:~$ knx got add 4 /p/4 22 [4]

Set a device installation identifier and a device individual address for the Sensor device.
```
uart:~$ knx dev iid 1
uart:~$ knx dev ia 2
```
Devices are configured. Use one of the Sensor’s buttons to control one or many of the assigned Actuator’s LEDs. The interconnections between buttons and LEDs are presented in the following table:

Control button (Sensor)

Controlled LEDs (Actuator)

BUTTON1

LED1

BUTTON2

LED1, LED2

BUTTON3

LED1, LED2, LED3

BUTTON4

LED1, LED2, LED3, LED4

Control button (Sensor)	Controlled LEDs (Actuator)
BUTTON1	LED1
BUTTON2	LED1, LED2
BUTTON3	LED1, LED2, LED3
BUTTON4	LED1, LED2, LED3, LED4
