I have, in the past, been able to import weight data from my Withings scale into SIDiary -- and the Withings scale is shown in the list of devices.
I don't do this regularly (alas), but when I tried to do it this evening, I kept getting error messages.   I've tried to manipulate it (for example to remove the time from the date column and put the time in a column all its own).  I was able to do that, but it left 0:00 behind in the date column, etc.
Here are the first dozen or so lines from Excel:
Date   Weight   Fat mass   Bone mass   Muscle mass   Hydration   Comments
12/16/2016 9:19   262.7   76.5   9.3   176.8   127.4   
12/15/2016 9:53   263.2   72.1   9.7   181.4   130.6   
12/13/2016 8:24   263.8   71.6   9.8   182.4   131.4   
12/12/2016 8:05   264.8   69.5   10.1   185.2   133.6   
12/11/2016 8:10   265.8   68.3   10.2   187.2   135.2   
12/10/2016 7:26   266.5   69.7   10.2   186.6   134.7

12/6/2016 8:04   264   87.8   8.7   167.5   122.4

12/3/2016 9:08   265.7   86.2   8.9   170.6   124.3   
12/1/2016 7:23   263.7   78.2   9.3   176.2   127.1   
11/30/2016 8:20   264   87.7   8.7   167.6   122.4   
It would be fantastic if I could import this date (weight data only) from the Withings site by simply downloading the .csv file from Withings, and uploading it into SIDiary.
Is that possible?
Or do I need to manipulate the file in some way?  It's currently a .csv file.  
Thanks for your help.  I appreciate it, as always.
