 ZHA integration uses a hardware independent Zigbee stack implementation with modular design which means that it can support any one of the many Zigbee coordinator radio modules/adapters available from different manufacturers, as long as that module/adapter is compatible with [zigpy](https://github.com/zigpy/zigpy).
 
+Note! Zigbee 3.0 support or not in zigpy, depends primarily on your Zigbee coordinator hardware and its firmware. Some Zigbee coordinator hardware supports Zigbee 3.0 but might be shipped with an older firmware which does not. In such a case you may want to upgrade the firmware manually yourself.
+
+Some other Zigbee coordinator hardware may not support a firmware that is capable of Zigbee 3.0 at all but can still be fully functional and feature-complete for your needs. This is very common as many, if not most, Zigbee devices do not yet Zigbee 3.0. As a general rule, newer Zigbee coordinator hardware generally supports Zigbee 3.0 firmware and it is up to its manufacturer to make such firmware available for them.
