Thanks.
Will buy one to try. 
Anyone founded a way to connect automatically Aqara sensor to best zigbee coordinator?
Having this issue now. For some reason the Aqara motion sensor placed all the way in the garage is losing range, and not detecting motion. Purchased an innr smart plug hoping to use it as a repeater, but having trouble getting it to sync up with the motion sensor. The door sensor however has synced up to it just fine. Anyone have any other suggestions in improving zigbee range?

Suggest buying one “IKEA Trådfri Signal Repeater” for each area to build a good baseline for the mesh:

Alternatively buy a few of ITead’s “Sonoff Zigbee 3.0 USB Dongle Plus” and flash them with Zigbee Router firmware → https://community.home-assistant.io/t/iteads-sonoff-zigbee-3-0-usb-dongle-plus-based-on-texas-instruments-cc2652p-20dbm-radio-mcu-now-sold-for-14-99/340705
Known limitation with Aqara/Xiaomi firmware. Only way is to manually re-pair device at final location.
