…. the choices seem to include: 1. Use weewx database and make your graphing package do the smoothing (in the way I presume wview does) 2. Use weewx database and weewx graphs - rather than making your own graphs 3. Increase archive interval to ensure every archive record contains at least one reading for each sensor - I think some sensors only output every 15 minutes (=900 seconds) 4. Explain what you feel to be wrong or 5. Return to wview
As a further point you seem to be jumping around many different station types and drivers. Stations of different types emit different data and weewx will cope with each. However the config file needs to be set up for each station type with regard to hardware/software preferences, archive interval, hardware/software record creation etc. HOWEVER - it is overriding within weewx that an archive record contains the average value for a reading during an archive period. If there is no reading there is no value to store. In the hgardware manual there is information regarding each station type - and for example the config options for a fine offset station would involve periodic polling at about 60 second intervals (no point in more frequently as station does not emit any faster) and software record creation rather than hardware …. and so on. The options to use for fine offset are not the same options you would use with a davis station, so it is not possible to just change drivers when changing station types. My FineOffset has run for several years without issues.
