User manual, how to use zigbee function

Zigbee OnOff Light(End Device)

Arduino IDE Tools：

• Tools -> Board: ESP32H2 Dev Module
• Tools -> Erase All Flash Before Sketch Upload: Enable
• Tools -> Flash Size: 2MB
• Tools -> Zigbee mode: Zigbee ED (end device)
• Tools -> Partition Scheme: custom

Zigbee On Off Switch(Coordinator)

Arduino IDE Tools

• Tools -> Board: ESP32H2 Dev Module
• Tools -> Erase All Flash Before Sketch Upload: Enable
•  Tools -> Flash Size: 2MB
• Tools -> Zigbee mode: Zigbee ZCZR (coordinator/router)
• Tools -> Partition Scheme: custom
• Zigbee ZCZR 2MB with spiffs

Awọn igbesẹ lilo 

1. Ensure that the coordinator is running and creating a network, burn the On Off Light code to the terminal node device.
2. After the device is started, it will automatically search and join the network, and On Off Switch will send light switching instructions at regular intervals.

Zigbee Scan Nẹtiwọọki

Arduino IDE Tools

• Tools -> Board: ESP32H2 Dev Module
•  Tools -> Erase All Flash Before Sketch Upload: Enable
• Tools -> Flash Size: 2MB
