# Light Bulb Example 

This example demonstrates how to configure a Home Automation on/off light on a Zigbee end device.

## Hardware Required

* One 802.15.4 enabled development board (e.g., ESP32-H2 or ESP32-C6) running this example.
* A second board running as a Zigbee coordinator (see [HA_on_off_switch](../HA_on_off_switch/) example)

## Configure the project

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

## 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-]``.)

## Application Functions

- When the program starts, the board will attempt to detect an available Zigbee network every **1 second** until one is found.

```

- If the board is on a network, it acts as a Zigbee end device with the `Home Automation On/Off Light` function.

- If the board receives a `On/Off` command from the joined network, the LED on the board will adjust accordingly.
