Hi, Data is great but logs are better :) Quite possible you have corrupt station memory (have a look here <http://weewx.com/docs/usersguide.htm#html_generated_but_not_updated> in the User's Guide), not uncommon when disconnecting/interrupting power to a Davis station. If you want to take a punt and don't mind losing any records in your station memory, you can clear the console memory using wee_device <http://weewx.com/docs/hardware.htm#vantage_clear_console_memory>. If you don't want to take such drastic action you can check the logs first, in weewx.conf you set debug=1, save weewx.conf then stop/start weeWX. Let it run for a couple of archive periods (appears you have a 30 minute archive period from your data) then post the log.
As an aside, if you want an archive interval somewhat less than 30 minutes, use wee_device to set the archive interval <http://weewx.com/docs/hardware.htm#vantage_archive_interval46> as required. Note that any use of wee_device must be done with weeWX stopped. Gary -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
