There's a variety of Consumer Access Devices (CADs) which talk to the HAN and provide data in whatever format they feel like (mostly uploading it to their own cloudy motherships, although one or two offer local access). The Octopus Mini is a CAD, but it's not the only one.
Using the Bright app and no CAD I did manage to get half hourly data with only a few minutes delay, so there does seem to be a way to get more timely data from the DCC. Only a CAD will give you live data, though.

Firstly, why would it, secondly, would it really matter if it did?
What are Octopus going to do with that information, even if they had it
- come rushing over, to make free use of my Internet? You don't suppose I might notice something making such an unauthorised connection?
And, with any decent router, you can have wireless devices, that don't need to interact with your normal home network, on a different VLAN - just as you can allow guests yet another VLAN.
An employee with access to that information could misuse it to carry out illegal activity on your network. It's unlikely, but the damage could be bad.
How would the wifi password help? Unless they drove up in a van and parked outside your house?
They already have a device on your network that has access to the internet, so if an employee is going to do bad stuff then they can do it through that. It's a very weedy device though, a bitcoin miner it ain't.
Putting such things in a separate untrusted network where they can only see the internet and not each other or your important machines is a generally good plan, though.

Do large outfits with many premises tend to have their own networks (internets) linking all their facilities, with just a couple of large pipes linking them to the Internet? Or does each facility tend to have a router connecting the building to the Internet. I am minded to wonder how it is that these people get hacked. ISTM that this applies in spades to such as Network Rail or National Grid. These people should certainly have all their stuff on their own private network (thats what 10/8 is for) and hard-nosed firewalls at the edge. That way they can quickly isolate themselves. But do they?
That was called an "intranet" at my work.
A generally bad idea.
And it works the way you would think. Can't access it from outside the company. Can only be accessed from inside company buildings. Only hackers can readily access it (or so we were told later on).
It's better to have departments siloed, for security reasons.
In terms of the span of the network, one of the nodes was in the middle of the Pacific Ocean. I don't know where exactly. But I expect a few employees like me, tested the ping to that one. That was likely our Beach Umbrella division :-)
