I have the Opple 6 button controller. It is Zigbee 3.0. It pairs, but a press of button 2 turns everything Zigbee in your home ON and button 1 turns everything Zigbee OFF. It’s not a good scenario when one of those things happens to trigger your alarm and it’s early in the morning. 
This issue is known by others and SmartThings has the same result. There’s no driver and it’s not believed there will be a fix for that particular problem. I’m using it with the Aqara HomeKit hub which is not Zigbee 3.0 and syncing it via Homebridge. It works great that way, and I’m using rule machine to give me toggle capabilities, which HomeKit doesn’t support.
The T1 devices are indeed Zigbee 3.0, but I don’t have a need for them so have not purchased any.
