I had the xFI Advanced Gateway (also known as XB6) for a couple of weeks with my Comcast gigabit internet service back in June before replacing it with a purchased third-party modem and router (Netgear CM1000 and R7800).
The short answer is yes, it will provide those services.This is Miio Gateway EU version implementation based on encyryption-less miio_client developed by 01 with custom miio_client integration for HA.
