Let's check what's going on in weewxd. 1. Set debug=1 in weewx.conf. 2. Run weewxd directly from the command line <https://www.weewx.com/docs/5.1/usersguide/running/#running-directly>, and post the output from startup through the first archive record. Make sure you post both LOOP and REC outputs. This will show us what values weewxd is processing. 3. For the same period of time, post the system log from the startup through the first archive record. This will show us internally what weewxd is doing.
