D|o make sure that you are, as matthew said, comparing apples with apples. What is the time interval in use on the weather smart system, and what is the archive interval in the console itself? I still do not see how you managed to obtain records for the same time period into two different systems. I suspect that for the weewx run you should have looked only at the REC entries, and not the LOOP records. The REC records would/should match the archived records in the console, and the weathersmart system when it started up would retrieve the same records from the console.
