Xiaomi new gateway will work with Mesh lights?

Hello!
I’m looking at this device https://www.gearbest.com/home-smart-improvements/pp_3005477209849496.html?wid=2000001 ( Xiaomi Mijia Smart Multi-Mode Gateway ZigBee 3.0 WIFI Bluetooth Mesh App Control Apple Homekit Hub ) in order to control Bluetooth Mesh Downlights. Will it work? And will it be possible to control lights over Google Home?

Yes, it’s a bluetooth mesh gateway and so it supports mesh lights.

Yes.

Is this the newest version of a mesh hub? Also will it work with amazon Alexa? I have mesh lights I need to automate.

I’d like to ask one question: “What’s bluetooth mesh spec on your Hub? SIG Mesh Standard or Properties Bluetooth Mesh”

Is it SIG mesh standard too??

I’m not sure what Sig mesh is but I think Yeelight BLE mesh is proprietary
