I have an Acurite 6045 feeding data via SDR to my weewx (3.9.2 with the 4.0
database schema) on RPi4 setup. It's working fine, but I'd like to fine
tune what goes into the database a little. The 6045 sends the last
distance recorded with every packet, even if there haven't been any new
strikes. I want to set distance to null in the database if there aren't
any new strikes. The strikes that go into the database
(lightning_strike_count) are derived from the delta of strikes_total
reported with each loop, as configured in the driver's section of
weewx.conf (below). Is there a way to tell either the driver or StdQC to
override distance based on the derived lightning_strike_count field?
Something akin to "if lightning_strike_count < 1 then lightning_distance =
null else lightning_distance=distance.0027.AcuriteLightningPacket"? Or is
this going to be as involved as the whole wind direction when no wind speed
topic? I'd like to try and put the right data into the database rather
than scheduling a nightly sqlite update to correct the distance field. TIA
for any suggestions.
