Expandable Zigbee Repeater Solution (With Temperature, Humidity, Pressure and Light sensors)

I have been testing Xiaomi motion sensor a child of this DIY module. It has been working stable in a last few days. It seems that TI Zigbee stack can help with problematic Xiaomi devices. I am looking for Xiaomi devices that had drop out problem to test. If you guys have experience with one, please let me know.
