They just add up the incremental ½ hourly kWh readings for your night-time usage and the ½ hourly kWh values for your day-time usage, which as you say gives you your separate day and night kWh totals, to which they apply the relevant tariff value.

I don't know if this is how the Smart-Eco7 billing is supposed to work, but it seems logical to me that they just need to apply the relative ToU tariff to the actual time of use, without needing any meter readings - that's how the NextDrive tariff works for non Eco7 meters.

Have you downloaded your CSV data from Bright/Glowmarkt yet to see if this compares to your billed totals?

I'm still investigating the Bright Glowmkt thing. I'm just trying to tie up the meter readings with billings!
The issue you've raised there is that the so called smart discount periods could be different to the eco7 periods.
However if every half hour theyre reading the day meter and the night meter they can just attribute the tariffs correctly to the day night meter readings

It's probably worse for people with a single rate meter and a random rate smart charger which starts and finishes 30 minutes after the tariff change
