With the recent Aqara smart home sensors a few people have been wanting Zigbee gateways to control the sensors so I've found one on AliExpress for a good price. This is the basic version of the Aqara hub so it lacks features found in the others like a speaker and IR blaster. The USB port is for power only.
Featuring Zigbee 3.0 with support for up to 128 devices, powered via USB, built in WiFi repeater (max 2 devices) that uses other Aqara sensors for extra range, connects with the Aqara & Xiaomi app for management and supports Apple Homekit, Amazon Alexa, Google Home & IFTTT.

AU$ based on current Mastercard rate, GST inclusive and stacks with Cashback / Socialgood.
why not use m1s alarm or g3 camera as the hub
