**Anything special about the device?**
Using the same method of adding Mi Door and Window Sensor 2, the plugin was able to identify all device types correctly but stated as Not Supported in HomeKit. These device types supports native HomeKit feature like temperature sensor, submersion sensor, etc.

Based on helpful thread here #442, I manage to expose the (not-yet-supported on the plugin) Qingping Door/Window Contact sensor the same way as Xiaomi's ones.
