Zigbee supporting Esp32 module with Arduino

Ok, I get it now.

So this effort is to get an ESP32 to run zigbee directly, without Arduino?

Please correct me, but it seems like this was already done.

I'm still shocked that I can't buy a thermocouple zigbee/z-wave sensor off the shelf. All I ever get is: build one yourself with ESPxx, arduino, or whatever, which I can't/won't do.

Sorry for distracting.
