Weewx looks in your database for the last timestamp, then downloads everything from the Vantage after that time. So, your last data record must be just before 2017-03-19 17:30:00.
If you want to get everything, you could try using the wee_device utility with the --dump <http://weewx.com/docs/hardware.htm#vantage_dumping_the_logger_memory> command <http://weewx.com/docs/hardware.htm#vantage_dumping_the_logger_memory>. This will dump *everything*, including data you already have, so expect a lot of "duplicate key" warnings in the log. -tk On Sun, Mar 19, 2017 at 10:27 AM, <[email protected]> wrote: > Hi everybody! > > I just finished installing and configuring weewx on a RPi3 with my Davis > Vantage Pro2.
