@DebF_EONNext - even more interesting is that the tariff rate timings picked up from the meter (via the DCC) are 00:30 to 07:30 and not midnight to 07:00 as expected (although the billing is done from midnight to 7)

@geoffers so what we have been told is that the IHD will only show 1 rate it won't show 2 as I mentioned above but I am not sure if this is interchangeable as in if it shows the day rate during the day and night rate at night, it's not something I've ever been asked to look into before so leave this with me so I can get a clear answer on this as this would make so much more sense!

The latter part I can explain!

When you are on 2 rate meter you are billed from 00:30 - 07:30 rather than 00:00 - 07:00 - this was due to some of our customers having issues with heating and hot water not coming on at the allocated time as it somehow interfered with the time switch when they were set to switch at 00:00.

We were having to arrange emergency call outs to get people's hot water etc back on so it was trialed with 2 rate meters to start 1/2hr later and it stopped the issues with the timers. It was changed then so that customers who have a 2 rate meter will see their off peak start at 00:30 and end at 07:30 instead. It is easier to manage as a blanket everyone on the 2 rate starts at the same time rather than individual accounts billing at different times.

Also the good news is that the IHD now appears to be correctly showing the true costs based on the two tariff rates (this is all done on the meter I think and just repeated by the IHD)

I checked what the IHD was saying my costs were at 7:45 this morning and it said 95p

Checking the ½ hourly data from the meter ... I'd used 3.44kW at 6.7p and 0.14kW at 24.36p plus the 68.12p s/c this comes to exactly 95p - Result!🤓

So the essential requirements are:-

To have the correct right tariff data sent to the meter by Customer services, and

Not setting one's own tariff data on the IHD, so allowing it to pick up the correct usage and pricing data from the meter.

Is that a correct summary? Anything else?

Sounds good - I think that now that EOn has got their act together they are automatically uploading both tariffs for Next Drive (and presumably E7 etc but I have no knowledge of how that works)👍

As I said in an earlier post, my previous attempt at getting both tariffs uploaded to the meter resulted in just the midnight to 7 tariff being loaded as a "single" tariff, and this then got switched back to the daytime rate when my tariff changed - so at that stage EOn didn't seem able to upload both tariffs, even though the meter was perfectly capable of storing them.

You can't set your tariff on the IHD itself, as that picks up the value from the meter.

However you could override the (single) tariff value read from the meter on the Bright/Ivie apps ... that is now unnecessary since both tariffs appear to be on the meter and are picked up by Bright
