There appear to be a number of issues.
The IHD shows the E10 off-peak time starting at 1330 for example, but the active register on the meter only swaps from peak to off-peak at 9 min 31 seconds later. This delay happens for every change. I understand there is an offset applied on smart meters but I can't seem to find the official offset displayed anywhere. The only way to find out is to sit and watch the smart meter until the active register changes!
The daily cost on the IHD seems to be incorrectly calculated using the 1330 time and not the time the registers swap over.
What happens with my bill? It's all seeming a bit fishy. If I think I am cheap rate at 1330 and start charging my car I am billed at the expensive rate for the first 9 minutes. This is not advertised anywhere on the unit or the paperwork. The IHD even shows me as on the cheap rate at 1330 despite the main meter waiting for the offset time to swap from peak -> off-peak .
Also I cannot view the whole tariff at once on the smart meter or IHD. I have to stay up to all hours of the night to see each tariff change. The smart IHD v3 is not very smart and only shows the currently active register. It doesn't show a break down of the registers ie day/night or whatever they may be labelled as. My Smets 1 meter could do all these things. The whole set up doesn't seem that open to auditing/keeping an eye on the tariffs loaded.
I guess I'm not hugely impressed with my foray in to the smart meter world. It started with a previous company trying to fraudulently charge me £1700 after swapping the day night registers. Now I have a new SMETS 2 and I can't easily keep an eye on the figures.
