Lightning 2000 example file

We’re having major thunderstorms around and my detector reports hundreds of lightning strikes.
The RPi logs every stroke in the log file. Today there were about 450. But the WD only reports 214.

Are there any other fields that need to be populated in the nowcast.txt file? Or do I need to adjust the update frequency?
I log a file every 60 seconds (python script in RPi), WD downloads this file from RPi (web server).

It’s not a major issue but if it worked I could write down nice how-to how to integrate own lightning detector with WD. Hobby boards is not available anymore so one alternative would be welcome.
