Original GitHub issue: https://github.com/OpenEPaperLink/OpenEPaperLink/issues/442

Describe the bug

When using the dayahead prices on my tags, i get a strange error. In the bottom of the graf is says the hours, and it starts right with f.eks 12-14-16 etc, but after 22 it goes 0-8-16-0-8-16-0-8-16-0

To Reproduce
Steps to reproduce the behavior:

Use the dayahead on a tag
Wait until you have the price for two days, instead of hours in the bottom it just repeats 0-8-16-0

Expected behavior
A few days ago this was working as intended.

Screenshots

Those times are returned by the api call to ENTSOE. They regularly have disruptions, and also some countries are switching to 15 minute timeframes instead of hourly, but I don’t know how that change will look.
See https://newtransparency.entsoe.eu/news?id=67b72ba9fc0da26e7b5fbce4 for the status page.
The problem will resolve by itself most of the time. If not, let me know, so we can reopen this issue and I will have a detailed look. In that case, also tell which country it involves.

This is still a issue. Country is Norway, zone is NO1.

The prices looks to be right, it is the hours and the line showing the current hour that is wrong.

The returned data is changed: it indicates an interval of 15 minute instead of 1 hour, but only every 4th value is returned so in effect it's still hourly... I will fix the google apps script to handle this.

@TylonHH commented on GitHub (Jan 24, 2026):

can the interval be set to 4 or something? 5 hrs is really odd, altought its starts with 10-16

optional question to cheap block hours: in the settings it says "Number of hours for cheapest consecutive block (e.g., 3 for dishwasher, 2.5 for 2h30m). Set to 0 to disable. Shows up to 2 non-overlapping blocks."
In my screen I only see one. How do I see two blocks?
