Read data of a Sonoff SNZB-02 with a Sonoff Zigbee USB Dongle Plus

Hello,
I need some help.
I would like to read and evaluate the data of a Sonoff SNZB-02 with a Sonoff Zigbee USB Dongle Plus.
Node-red-contrib-zigbee is installed and the devices have been detected.

I created a very simple node to see data. Unfortunately nothing arrives.

[{"id":"6e2ef515.42a62c","type":"debug","z":"427fc89b.e34038","name":"","active":true,"tosidebar":true,"console":true,"tostatus":true,"complete":"payload","targetType":"msg","statusVal":"payload","statusType":"auto","x":420,"y":620,"wires":},{"id":"1127628c.6201d5","type":"zigbee-converter","z":"427fc89b.e34038","shepherd":"69d62f4.628ecd","name":"","topic":"zigbee/${name}","settopic":"zigbee/${name}/set","gettopic":"zigbee/${name}/get","device":"0x00124b0022cf7747","attribute":"","payload":"json","x":220,"y":620,"wires":[["6e2ef515.42a62c"]]},{"id":"69d62f4.628ecd","type":"zigbee-shepherd","name":"zigbee Holger","path":"/dev/ttyUSB0","baudRate":"115200","rtscts":false,"channelList":[11,15,20,25],"led":"disabled","adapter":"zstack"}]

Does anyone have an idea how to extract data from the SNZB-02?

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)

I suggest using zigbee2mqtt and mqtt nodes rather than that node. Particularly as the readme says that it is work in progress and has not been updated for nearly a year. Zigbee2MQTT is what most use and you will find no difficulty get help with it.

Thanks Colin, it sounds like the best way. I'll it.
