Supported Targets	ESP32-H2	ESP32-C6

Light Bulb Example

This test code shows how to configure Zigbee end device and use it as a HA color dimmable light bulb

Hardware Required

• One development board with ESP32-H2 SoC acting as Zigbee end-device (loaded with HA_color_dimmable_light example)
• A USB cable for power supply and programming
• Choose another ESP32-H2 as Zigbee coordinator (see HA_color_dimmable_switch example)

Configure the project

Before project configuration and build, make sure to set the correct chip target using idf.py --preview 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-].)

Example Output

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

Light Control Functions

• By toggling the switch button (BOOT) on the ESP32-H2 board loaded with the HA_color_dimmable_switch example, the LED on this board loaded with HA_color_dimmable_light example will change the color from red, green to blue and also light level will change.
