[ESP32] How to read data from Zigbee sensors using ESP32-H2 and send to ThingSpeak?

Hi

I have built a small Smart Home in my flat based on Zigbee devices.

The system consists of a few Zigbee temperature sensors, a few Zigbee enabled sockets.

Everything connected to a Zigbee 3.0 gateway and managed by the Smart Life app on a smartphone.

In this configuration, everything works perfectly.

I would like to extend this system with the possibility of sending the measurement results to a portal such as ThingSpeak.

Just sending data e.g. from a DS18B20 temperature sensor to ThingSpeak I have already mastered and use ESP32 for this.

However, I have no idea how to connect to the Zigbee network and take readings from individual sensors.

I have found an ESP32 - H2 module that theoretically supports Zigbee networking, but I can't write or rewrite any code.

Can someone please help me?
