temperature fluctuations on the graph

[Simbor]

I haven't idea about the probable cause
Occurs occasionally without apparent cause.

Before restarting Cumulus, the fluctuations are so intense that the line is similar to a single block "thickness" about 1,5/2,0 ° C.
Restarting Cumulus, it looks like a picture.

On the EasyWeather's graph, it not appear.

Presumably you're not running Easyweather and Cumulus at the same time, so EW only has the logger data, which won't show fluctuations so much. This is the same as what happens when you restart Cumulus, because it only has the data from the logs to plot. The rest of the time it's using 'live' data, and almost certainly accurately recording the readings from your station, which is the source of the fluctuations. I seem to remember someone else with a Fine Offset station posted a graph recently which showed the same thing.

Hi Steve and thanks for your support.

Cumulus is always ON, on the Server.

EasyWeather is only opened after closing Cumulus.
Yesterday I opened EW to compare the graphs, but usually it is always closed.

My setting's station:

I use Cumulus for over 5 years and has always been perfect . I had never given these problems.
That is the fault of the weather station?

PS: My calibration

Cumulus just records the values that it gets from the station. Have you looked at the temperature on the console and compared it with Cumulus while this is happening?

Your temperature spike removal setting is very low, a change of 0.7 degrees is not what I would call a spike. You may cause Cumulus to discard valid readings with that setting. But normally that would cause the readings to 'flat line', and if you don't get that then you're probably OK.

Unfortunately, no.
It always happens at times when I sleep or are at work.

Since there is such a setting (spike removal), it has always been 0.7 and it never gave any problems.

If I remember correctly, these fluctuations happening even with the previous weather station (WH1080).

PS: in the meantime, just not to miss anything, today it stopped working the light sensor

[Super-T]

Was it particularly windy at the time of the spikes. I have found that I get more temperature variations when windy.

[Spider-Vice]

The wind connector has to do with the temperature sensor in the FO circuitry. But that's all I know, I'm sure someone more enlightened will come here and explain.
