Strange behaviour after reset of WH1080

[phloks]

Hi,

The other day I saw that there were no more updates to my website.
This website gets it's info from a Rpi, that sends all necessary files through FTP to the machine my website runs on.
It was working fine, until a some days ago.
I switched to the Rpi, and saw cumulusmx saying something like unable to get data from station - maybe reset is necessary.

Although I saw no problems on the WH1080 console itself, except for the fact that memory was full, I went along and took out the batteries, and disconnected the usb cable.
After reconnecting and restarting cumulusmx, data is being shown on the site again, but not like it used to.
Especially the gauges page seems to be in error, i.e. the temperature gauge starts at -140 C and ends at 40 C. The temp displayed, however, seems to be correct. I can not say that of the rainfall gauge which is displaying 506 mm of rain.....
But the strangest thing is that most, but not all, gauges seem to start over every 5 seconds. That was not the case when I first started cumulusmx.

Questions:
1) Why do the gauges reload themselves every 5 secs (it did NOT do that previuosly, even though the time has always been 5 secs) ?
2) Where does those strange readings come from (temp gauge, rainfall...) ?
3) Can it be that Cumulus lost track when memory of my WH1080 went to full ?
4) Is there some procedure to follow after you reset the memory / console ?

BTW, if you want to look for yourself, please be my guest : https://www.hanslammerts.nl/cumulus/gauges.htm
Hope someone knows the answer.

Thanks
Hans

The gauges behave like that when you have an extreme invalid reading - you have a low apparent temperature of -121.6 at 16:21. Unfortunately, one of the side effects of resetting the console is that you can subsequently get invalid data, and this needs to be edited out. It's nothing to do with the memory being 'full'.

Do you have the correct station type selected? Having the wrong type selected is a good way to get wildly inaccurate data such as you got.

Hi Steve,

Thanks for answering my question.
Yes, I do have WH1080 defined as the station I use. Don't know why there has been an error, making CumulusMX unable to read data.
Maybe the extreme wrong data was written at the time the error occurred ?
Do these extremes also account for the reload behavior every 5 seconds, something I did not see before ?

Can you please tell me how I can "edit out" these extremes ?
Or is this just RTFM ?

Thanks again,
Hans

Yes, I do have WH1080 defined as the station I use.

There isn't a WH1080 setting. There is "Fine Offset" (the one you should be using) and "Fine Offset with Solar Sensors".

Don't know why there has been an error, making CumulusMX unable to read data.

It's a common problem with Fine Offset stations. Are you using the "synchronise Fine Offset reads" setting in Cumulus?

Maybe the extreme wrong data was written at the time the error occurred ?

Yes, possibly. Are you using the "spike removal" settings in MX?

Do these extremes also account for the reload behavior every 5 seconds, something I did not see before ?

Yes, as I said.

Can you please tell me how I can "edit out" these extremes ?

There's information in the FAQ and wiki about correcting data, but note that with MX you have to edit the files manually as it doesn't yet have any of the build-in editors for correcting data.
