Variable tariff accounting (Intelligent Octopus)

Questions
#1

I’m on a tariff which varies in 30-minute slots throughout the day, depending on time and also whether my EV is charging.

As part of the 5-minute uploads I want to define whether the data is for peak or off-peak usage so that TOU and consumption data is correctly reported.

Has anyone found a way of doing this already?

#2

Use a tariff feed instead, which enables 5-minute tariff updates using Extended Parameters.
