These are smart power sockets which you can link direct to Google Home or Amazon Alexa without needing extra bridges/hubs/hardware like the Xiaomi range.
Some notes I gathered from previous deals:
* These are rated up to 2000W (instead of Aus standard 2400W), so high power appliances like heaters/AC will not work with these.
* Native Google Home, Alexa and IFTTT integration and can be flashed to support MQTT
* These are technically Chinese sockets which are upside down compared to ours - keep in mind when deciding where to use it
* They have not been tested for Australian safety specs. That said, teardowns and user reports state decent build quality.
I ordered one of these last time around and found they are a bit fiddly to setup for my Google Home at first, but once they are connected they are awesome. I have mine powering my bedside lamp in the bedroom. Google turns it on for me before I even get there.
