Supported Targets ESP32-H2

Light Switch Example

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This test code shows how to configure Zigbee end device and use it as a light switch

Hardware Required

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

Configure the project

Before project configuration and build, make sure to set the correct chip target using idf.py set-target esp32h2.

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 light bulb example will be on and off.
