This suddenly started again.  Its been a year.  Nothing changed to cause it.

Is weewx going to offer a solution internally considering how many of us use davis pros?

Perhaps if you worded your question with a much less demanding tone you might get some answers....

Look at your previous posts in https://groups.google.com/g/weewx-user/c/iGR21sLZ7VM/m/BOMROMWDAQAJ in which you had the same issues and seem to have solved it then.
