Wind Speed graph is flat lined....all of a sudden

[geewizard]

My station windspeed graph has flat-lined for some reason. I haven’t changed any settings. Any ideas how to fix it?

I don’t know the Tempest station, but are there any batteries that might need to be replaced?

The same thing happened to me last night. Low battery!

I don’t think it’s a low battery in my Tempest…but I could be wrong. Note the battery voltage from Cronweatherflow:
