Here's a relevant section of the log which shows the Acurite Atlas
lightning sensor sending the last distance (10) reading over and over.
This is expected Acurite Atlas behavior, and the reason we have to put the
"if > 0 else None" statement in our [[Corrections]] section.
Referring back to the 5.64705882352941 value seen in my database:
I wonder if weewx isn't expecting a decimal reading to be in
lightning_distance?
And that sends it into confusion?
