"Interpolate values" looks weird about dwd_weather

[FL550]

I'll have to look into this. Thanks for reporting!

As this only occurs in specific points in time, I think it might have something to do with an update of the forecast data.

The algorithm I use is a linear interpolation, so nothing special. I'll have to further investigate.

Hey @FL550,

Thanks for looking into it.

If I look at the graph it looks to me like there's a shift of half of the interval forward of the interpolated values.

So half of the interval gets no interpolation, then the second half of the interval gets the first part of the interpolation and then the new value creates a 100% gradient in the graph.

Hm, I can't confirm this with my setup. I only have a step one time a day, at 11 o'clock. Here is a closer look of one day but this is the same for me for other days:

Can you please have a closer look at your data so we can track this down?

@RubenKelevra any update on this?

[RubenKelevra]

Hey @FL550, this graph doesn't look like it's the same one I'm having troubles with.

I'm seeing the issue especially on the solar radiation one.

Can you check this graph on your end? Maybe the issue is limited to this one?

[RubenKelevra]

Well, I think it's also visible on the "cloudyness" graph. But it's so much random data, I'm not sure about it.

Solar radiation however should be smooth, but it's stepped with smoothed out parts in between:

@RubenKelevra very strange, I don't have this in my sun irradiance sensor, only a slight step at 11:00 which is due to a data update:

Can you please tell me your station id, so I can have a closer look?

My temperature (and also the other values) graph looks very strange, too. Interpolation ist activated.
