@Royston_Vasey_No1 I was wrong. The meter adds the standing charge into the daily costs, which are then reflected onto the IHD display. I believe this takes place at the start of each day, so the IHD "so far today" cost should always include the standing charge
@“Eleanor at Bulb” you were right both times
You can scroll through to see the standing charges for both gas and electric, and the currently active unit rates.
Then, as you say, the standing charge is also added on to the cumulative cost. One my SMETS1 display, the standing charge gets added to the “so far today” screen at midnight, or within a few minutes afterwards.
Yes, I am the kind of person to have stood there watching it at midnight to see what happens … :#
My tariff info is currently wrong in any case, so it’s not particularly useful. The tariff cost was first pushed to the meter at the point of registering the 3 rate tariff. But after that, there’s no way to update the prices other than registering a full tariff change. Trying to rewrite the tariff with the same tariff in order to push new tariff prices gets rejected. It sounds like the only way would be to push a change back to the single rate, and then push the 3-rate again at which point the new prices would be updated, which would likely cause all sorts of confusion. Ah well.
