The further I go, the more complex it is getting. First, yes I have a WS-2813U-IT and yes, I did set the relative pressure to match the local weather service.
I don't want to muddy the waters any more, but how is it that I stopped the wewx service but it is still reporting? I'm still trying to understand this thing.
