You would be "making up" data, which is very much against the philosophy of WeeWX. Nevertheless, if you really want to do this, it is possible. Basically, you do a database look up for the previous record. If you are using a 60 second archive period (very short, BTW), it would look something like this (NOT TESTED):
#set $now = $current.dateTime.raw #set $then = $now - 60 <p>The temperature now is $current.outTemp; for the previous record it was $current(timestamp=$then).outTemp </p> On Mon, Apr 1, 2019 at 1:02 PM <[email protected]> wrote: > My vantage vue station and weewx are set that they save the meteo values > every minute. > > I there a way to "remember" a value from a previous iteration? e.g., say > that windDir is N in the n-th data set, I want to use it in the next > iteration, the following minute.
