Useful links

All programs are based on examples from the Arduino ESP32 library (there is a Zigbee subfolder). However, this library is largely dependent on the parent esp-zigbee-sdk. The subdirectory components/esp-zigbee-lib/include/ contains many files that define, for example, cluster and attribute settings for the various devices.

Another useful source of information is provided by the Espressif documents with the Zigbee API description.

If you are working with devices from the Chinese developer Tuya, you should take a look at the documentation, e.g. a technical overview of a Smart Plug energy meter.
