Cumulus Support

Yes, I can see that from the files you uploaded. Perhaps the USB interface on your console has locked up - a common problem with Fine Offset stations. Presumably you are you using the ‘synchronise’ setting but this hasn’t helped? All I can suggest is the same as always, that you reset your console.

After restarting Cumulus again it connected to the station and the pressure value is correct.

I restarted Cumulus again and it connected to the station. Now the pressure values are correct.

Now the temperature trend graph is empty. If I delete tempdata.json on the site and update it from Cumulus to the site I can see the respective temperature graph but only for a while. The other trend graphs are from December 2. The file ftplog.txt has 307MB, the only date that it has is 2016-11-01 and it hasn't tempdata.json. I know that Cumulus has some difficulty to upload the files but it must have some other thing wrong.

The tempdata.json file that you delete, is it zero length?

Delete the ftplog.txt file and then turn on ftp logging.

The file temdata.json was not emty. I deleted the file ftplog.txt in Cumulusmx because I didn't find it in the site. As I didn't find a way to logging ftp in dashboard and I have logging=1 in [ftp site] of Cumulus.ini, I rebooted Cumulus.

Now I can see the temperature trend graph updated!

You were probably having ftp issues resulting in a truncated file.
