Cumulus Support

Cumulus was connecting to my weather station without a problem for about 3 months, then it stopped without warning. It went about a month without logging any information, then all of a sudden it downloaded all the saved data in the weather station, but then stopped downloading again about a day later. Now it is not working and I would like to figure out why. My computer recognizes that the ambient ws-2080 is connected. Please let me know if you need more information.

Thanks,

Please zip up the diags folder and attach it.

here you go

It looks like your station needs a reset (remove batteries and USB cable), the memory locations aren't showing expected values:

7/14/2013 09:28:38.004 : EWUSB: EW startup data line 01 55 6F 00 2D 00 5E 00 2D
7/14/2013 09:28:38.004 : EWUSB: EW startup data line 02 00 7F 00 2F 00 1E F5 FF

7/14/2013 09:28:38.035 : EWUSB: EW startup data line 04 85 7F 00 CB 06 00 A0 6D
7/14/2013 09:28:38.035 : EWUSB: Bad startup block 0, discarding. Byte 0 = 55 Byte 1 = 6F

There also seems to be a USB connection problem:

If you don't want to reset the station, or it doesn't help, you can disable the check on the first bytes of memory by adding a line to the [Station] section of cumulus.ini:

EWdisablecheckinit=1

You may find that you get bad data readings if you do this, though.

By the way, you are using an old version of Cumulus which is no longer supported. It's quite possible that the setting I described above doesn't work in that version.

I updated to the new version of Cumulus and added the line that you suggested and everything is working great! I was worried that I would have to reset my weather station and loose all the data that was in it but I did not have to do any type of reset.

Thank you very much for your help!
