yes, there is a way
you need to delete those repeated flat lines
in the WD logfile
then convert the log file to data file (and then also recreate the last 31 days data file ) (see under action)
make sure windows is not set to power down (select suspend) the USB, I do have a you tube video about windows power settings
I have added in a check for flat lines like this, so that WD stops updating the data. but not for the wmr300, but I could do that
re WU, yes, the data history that is caught up on start up is sent to WU (make sure you have a recent version of WD)
