Lightning showing in history

No lightning is around.
Not showing on weather app.
But history the past week or so is showing numerous strikes, sometimes in the 100s!

Station ID 33935

Perhaps some local electrical “static”/interference?

Is this new behavior?

It is but the unit isn’t actually detecting anything whether sferics or manmade. It’s just showing phantom strikes in the history page. No alerts sent through the app.

The Tempest unit is on top of a tower far from any manmade EMI sources. It has not restarted in many months and the firmware is out of date. Perhaps it needs a restart?
