ITead's "Sonoff Zigbee 3.0 USB Dongle Plus" (model "ZBDongle-P") based on Texas Instruments CC2652P +20dBm radio MCU now sold for $19.99

FYI; @leonschenk posted now in OpenHAB community forum here Discussion about Texas Instruments Z-Stack 3.0 and CC2652 and CC1352 Zigbee Coordinator adapters with openHAB ZigBee Binding - #4 by leonschenk that he now picked up the development where @t-8ch left it, forking his branch of the zstack driver with Z-Stack 3 support to GitHub - leonschenk/com.zsmartsystems.zigbee at zstack/initial in order to continue the work of adding initial support for CC2652/CC1352 based adapters with Z-Stack 3.x.0 Zigbee Coordinator firmware https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator/Z-Stack_3.x.0/bin so hopefully once he feels it works good enough for review he will create a new pull request to the com.zsmartsystems.zigbee ZigBee Cluster Library Java framework/libraries GitHub - zsmartsystems/com.zsmartsystems.zigbee: ZigBee Cluster Library Java framework supporting multiple dongles that the OpenHAB ZigBee Binding ZigBee - Bindings | openHAB and other projects depend on.
