If you bind your service to loop rather than record then weewx will build an archive record at the archive interval, with the value being the average value for the period
if you specify use loop for hilo in weewx.conf then weewx will populate the max and min from the loop data and the archive record will contain the average value for the archive period if you do not specify to use loop hilo then min and max will be the highest archived value for the day or the lowest archived value for the day does this answer your question though?? oh yes, the min and max times will always be on archive boundaries unless use loop for hilow is specified since the source of the data is of course the archive record. so the way to specify the times of the max and min is for the data to be in loop packets rather than rec packets On Wednesday, 5 September 2018 07:30:35 UTC+3, Thomas Carlin wrote: > > Good evening! > > I have extended my weewx instance with several sensors build on the > ESP8266 platform with help from many in this community.
