Light Switch Sensor
###################

This sample demonstrates KNX IoT Point API device with one or four Light Switch Sensor basic Functional Blocks.
Each of them is built with a single Switch On/Off input Datapoint (Datapointype ID: 1.001, Name: DPT_Switch).

Supported devices
*****************

The sample supports the following development kits:

+--------------------+----------+--------------------------+------------------------------+
| Hardware platforms | PCA      | Board name               | Build target                 |
+====================+==========+==========================+==============================+
| nRF52840 DK        | PCA10056 | nrf52840dk_nrf52840      | ``nrf52840dk_nrf52840``      |
+--------------------+----------+--------------------------+------------------------------+
| nRF5340 DK         | PCA10095 | nrf5340dk_nrf5340_cpuapp | ``nrf5340dk_nrf5340_cpuapp`` |
+--------------------+----------+--------------------------+------------------------------+
| Thingy:53          | PCA20053 | thingy53_nrf5340_cpuapp  | ``thingy53_nrf5340_cpuapp``  |
+--------------------+----------+--------------------------+------------------------------+

Building and running
********************

This sample can be found in the :file:`knx/samples/light_switch_sensor` directory.
Build it by following the steps in the `Building and programming an application`_ page.

Testing
*******

Complete the following steps to test and debug the sample in the nRF Connect SDK:

1. Follow `Testing and debugging an application`_ guidelines.
   After successfully building the sample and flashing manufacturing data, the sample is ready to use.

#. To refresh the logs, restart the program by pressing the :guilabel:`RESET` button on your development kit.
   You should see the output similar to the following:

OpenThread configuration
========================

The application starts the Thread interface automatically, and either joins an existing network or creates a new one.

A mesh network uses the following configuration:

+------------------+-------------------------------------+
| Parameter        | Value                               |
