LeeDQ_EONNext. So, I have been doing some digging.
I now know the answer to my question. I know how the tariff data gets, or doesn’t, to the meter.
First the components. We know about the HAN already, as we’ve seen the lights for the HAN flashing on the meter. However, what I didn’t appreciate was that there are local ‘undefined’ communications hubs that each Smart meter connects to. These HuBs , located probably on local power line poles, communicate with each other, with the Smart meter and with a ‘central, Uber hub that acts as a master repository. This is collectively what the HAN is and it is used by all household electrical suppliers. The plan is that other household appliance companies can subscribe to the HAN and download and upload data. The HAN doesn’t touch the internet anywhere. It is entirely separate.
As such the HAN is a single thing and is not operated by the utility company. Each utility company subscribes to it and is allowed to put data in at the front end, provide the serial number of the meter and, bingo the HAN delivers it to the meter. Likewise in reverse with the meter readings.
Now we get to the interesting bit. The HAN is effectively a national asset. As such it is run by an organisation called the DCC. The DCC is, wait for it, actually run by Capita. Now it all makes sense. In my career I had many dealings with capita and they are without doubt the most useless organisation I have ever had the mispleasure of dealing with. Totally impenetrable, not interested in customer service and totally driven by the need to obtain as much profit as possible.
Now I understand why this is so hard for EON and everyone else; they have no control. It’s entirely driven by Crapita who have a monopoly and therefore no incentive to perform. In the words of Private Fraser, “we’re all doomed”. I can safely now predict that this will all remain broken; Capita run it.
