Try uninstalling the ZHA integration and instead install the Zigbee2MQTT integration. This allowed my nonworking ZigBee device with an exterior “TY-ZigBee” label, to finally expose it’s controls and internal information and work!
Manufacture: Tuya
Zigbee Manufacture: TZE284_fzo2pocs
Zigbee Model: TS0601
Back story: I have a high awning window that I wanted an automated opener for, but ZigBee window openers are hard to find!
I finally found this one, a ZM90E-DT-250N/A300 for about $105 which shipped directly from China. It came slowly, and with very poor documentation, and which talked about Wi-Fi rather than ZigBee. 
So after a failed internet search for the correct information, I finally guessed at how to pair it with ZHA (Zigbee Home Assistant), (I think by pressing the button 3 times, but this might have been after holding the button in for a long time).
ZHA is the default ZigBee integration for Home Assistant Yellow and easy to use, but once paired it wouldn’t show any entities.
So I started reading, and now after a week I finally got positive results.
First I read about how to fix a device with Querk code. But fortunately before I headed down that rabbit hole, I noticed that there are actually two ZigBee integrations, not just one.
So long story short, I uninstalled the ZHA integration and instead installed Zigbee2MQTT to give it a try. Installation instructions are here: GitHub - zigbee2mqtt/hassio-zigbee2mqtt: Official Zigbee2MQTT Home Assistant add-on
However, when using the Home Assistant Yellow, the ZigBee radio is not a USB device, but rather connected as an internal serial port. So you have to configure the serial section by entering this:
adapter: ezsp
port: /dev/ttyAMA1
baudrate: 115200
rtscts: true
