2000mm rain spike!

Earlier today at around 14:00 UTC the Meteohub agregate figures (and graphs) show my rain0 as having received 2000mm of rain.
According to Meteohub raw data the total that gauge has ever received is 142mm!

20080407132047 rain0 010 0 1390
20080407135033 rain0 010 0 1400
20080407155158 rain0 010 0 1420

I have recomputed twice, upgrading to 2.2e between the 2 recomputes.

Aggregate values still show the spike.

Any ideas?

Should I maybe try the new \"Cleanup Data\"?

I doubt that \"clean up\" will solve this. There must be something in the raw data.

To find it I usually start with a graph (min-max-bars), going down in the time scale until I have found the time it occured.
The I go to inspect the raw data. dont forget that raw data is in utc, so it might be an hour or two before or past the time you have spotted in the graph.

UTC! Of course.
Once I started looking at around an hour earlier than I had, it was obvious:

Code: Select all

20080407123433 rain0 010 0 1390
20080407123520 rain0 010 0 21390
20080407123607 rain0 010 0 1390
Thank you. :cheer:

Maybe someday when you allow for calibration & offset at sensor level ;) you can also allow for automatic handling of spikes (i.e. if data value jumps by more than a user specified value, ignore that data value).

We can all dream... :)
