paul,
thank you for the detailed problem description. you need to set the
accumulator for the lightning database field. as of weewx 3.7, you can do
this in the weewx configuration file, like this:
[Accumulator]
[[LightningStrikes]]
extractor = sum
[[LightningStrikesTotal]]
extractor = sum
you probably want 'REAL' instead of 'INTEGER' for the 'LightningDistance'
field (that will require re-creating the database, or manually modifying
the schema in sql)
