Octopus Flux rates both right and wrong

[kirmonkey]

Hi all,

I'm on an Octopus Flux tariff with cheaper rates between 02:00 and 05:00. This is correctly reflected in the 'plan' page of Predbat:

However, the rates chart and Energy rates pane seem to indicate a large deviation at 02:00 every day (up to -60,000 pence p/kWh):

I've set up Predbat with the Octopus Energy integration as the 'source of truth' for rates and I've had a mooch around both this project and Bottlecapdave for an answer, but don't seem to be able to find the root cause.

This is playing havoc with predicted savings:

As I don't think it's a bug, I've posted here in the discussion section (Well, the bug is in the operator - me)

I'm still running Predbat in monitor mode at the moment.

Could anyone point me in the right direction/ask me the right question to flag up where I've gone wrong?

Regards.

Richard.

You don't mention what version of predbat you are on, but I think it is a bug.

The problem is in the hourly pence per kWh figure when the rates change and I think comes from price divided by time interval and when the time interval is small around a rate change, the figures go screwy

I never look at this chart, but do see the same on Octopus Cosy (Predbat 8.25.14):

I'm going to move this to an issue.

Can you add your logfile please to the issue
