I can confirm 100% working after pairing via the IDE. The Network I’d found in the Event View from the hub showed the address and all I had to do is plug it into the New Device Network Id line.
I paired a Xiaomi Mi Smart Button and a Xiaomi Mi Smart Temperature/Humidity Sensor. The temperature sensor is highly sensitive to temperature changes (first observation).
The button works withe the generic button controller app.
