I accidentally unplugged my Vantage Vue from my PC and it was a couple of hours until I noticed. When I plugged it back in, Cumulus continued to report a communication error until I restarted it. However although Cumulus started recording data from this point on, it did not transfer the historical data which had been gathered by the logger but had not been transferred yet to Cumulus. Is there a way to make it do that?
The data file Apr14.txt contains copies of the readings that were gathered at the point where the cable got unplugged, for every successive ten minutes until I restarted Cumulus - so the graphs are flat lines for that period.

Re: Retrieving missed data from Davis Vantage Vue (USB unplu
You can force Cumulus to download 'old' data as described in the FAQ, here: http://wiki.sandaysoft.com/a/FAQ#I.E2.8 ... er_station
An alternative way (which doesn't involve editing any files) is to use the files from the latest backup taken by Cumulus before the problem occurred; it takes a backup each time it starts and just after midnight (or 0900/1000). Stop Cumulus and copy all of the files from the chosen backup folder into the data folder. It will then download data from the logger from the time of the backup to the current time.
