The archive period you refer to, is that the value set in the weewx.conf file? I have reduced that to 240 or 3 minutes. If I understand you correctly, the average is over the 3 minute period until the next write is done to the database. If I run weewxd directly, (sudo weewxd weewx.conf) the LOOP values are correct. Then I assume the values read (poll_interval is 2.5 seconds) in the 3 minute period is averaged and written to the database, is that correct? I'll monitor the readings over a few days to see if I can make any sense out of this.
