The archives doesn't include the value 0 because with the 2.7 version, I add a minimum of limitation in weewx.conf to 0.001 mm due to rain error calculation. I also did the same thing with the wind. In the xls file, all the empty lignes are fill as '*NULL*' in the recorded data and archives.
Normally, I get only one instance of weewx. Weewx is running on a raspberry. I already reboot the system. Do you know how see all programs are running?
