The short answer is “no”. Zigbee HA devices need coordinator to communicate with each other. This is what ST hub essentially is. You can use another compatible Zigbee coordinator instead of ST hub, but you absolutely need one.
After set Xbee module to be coordinator, smartthings sensor’s 64-bit address is found.
but response about some api command from smatthings sensor does not well recieved.
I want smartthings sensor to be controlled by microcontroller with zigbee without smartphone application,
So I will try it by referring to the article below.
Thanks to your advice, I was able to create a switch & sensor application using the S2C module + MCU as an End device.
And I have noticed that the S2 (B) module and the Smartthings HUB are not making good ZigBee connections.
Can you tell me the documentation that describes the F / W constraints for this problem?
