Yes, the price you pay for using software record generation. Also, I forgot about no_catchup being introduced in 3.9.1. That changes the logic during a startup catchup, now software record generation will also get caught up in the 'timestamp less than final' issue unless you set no_catchup = False. But then, as you say, you will miss out on any catchup records in timea when you do not have corrupt station memory.
Guess that's why I have a UPS as well :) Gary On Thursday, 17 October 2019 09:35:21 UTC+10, Thomas Keffer wrote: > > Immune, yes, but you also won't get any archive records stored on the > logger while your computer is down! > > On Wed, Oct 16, 2019 at 4:33 PM gjr80 <[email protected] <javascript:>> > wrote: > >> One other thing to keep in mind; the de facto standard mode of operation >> of a Davis station under WeeWX is to use hardware record generation, in >> other words WeeWX obtains and stores archive records from from the >> console/logger.
