# Light Switch Example

This test code shows how to configure Zigbee Coordinator and use it as an HA on/off_switch

## Hardware Required

* One development board with ESP32-H4 SoC acting as Zigbee Coordinator (loaded with HA_on_off_switch)
* A USB cable for power supply and programming
* Choose another ESP32-H4 as Zigbee end-device (see [HA_on_off_light](../HA_on_off_light/))

## Configure the project

Before project configuration and build, make sure to set the correct chip target using `idf.py set-target esp32h4`.

## Erase the NVRAM

Before flash it to the board, it is recommended to erase NVRAM if user doesn't want to keep the previous examples or other projects stored info using `idf.py -p PORT erase-flash`

## Build and Flash

Build the project, flash it to the board, and start the monitor tool to view the serial output by running `idf.py -p PORT flash monitor`.

(To exit the serial monitor, type ``Ctrl-]``.)

## Example Output

As you run the example, you will see the following log:

```

## Light Control Functions

  * By toggling the switch button (BOOT) on this board, the LED on the board loaded with the `HA_on_off_light` example will turn on and off.
