What is the Zigbee model/manufacturer of the device that you received? GiEX may now be selling a device from a new manufacturer; in this case, automatic detection will not work until the new fingerprint is added to the driver code. You can try to manually set this device group :
if you click on the 'Ping' button, do you see the RTT (Round-Trip time) attribute updated or you get a 'timeout' error?
In case of a timeout, you may have a Zigbee 3.0 pairing issue... Try this workaround.
Update: TS0601 _TZE200_myd45weu is the already supported device.
