It’s a BT (EE) Smart Hub 2. The “bridge” bit is just a functional element of the router. I think it’s either called modem mode or bridge mode so the router doesn’t do any of the routing.
What do you mean by “terminal”? And why is the service level I’ve signed up for relevant?
Ultimately, I am at a point where I know that I can’t (without a lot of faffing around) use the BT Hub just as a modem. My goal at this stage is to fix the Nabu Casa issue.
Unless you did something else, HA being hooked up to the router or the unify shouldn’t matter as long as it has internet access, as HA initiates the connection to Nabu Casa.
