I have a bunch of Xiaomi zigbee sensors (door/window, temperature, and water leak) connected to my SmartThings hub -- You just need to install a device handler and they will work fine (though from what I've heard Xiaomi devices don't work well with most repeaters -- these are pretty much my only Zigbee devices so they are connected directly to my hub and work great).
I don't trust Xiaomi for anything connected directly to my network, but zigbee devices connected through something that I (kind of) trust works for me.
