Thanks for the debugging info. You've obviously looked through the source code to see what the calculation uses!
A few questions: What hardware are you using? Did you set windrun to "software" in [[Calculations]]? Or, something else? Are the "zero" values truly zero, or are they null? It's a pretty simple calculation. Hard to see what's going wrong. One thing you could try is to insert a couple of temporary print statement in the code to see what values it is using and what logic it is following. -tk On Fri, Dec 29, 2017 at 1:35 PM, Michael Hornsby < michael.d.horn...@gmail.com> wrote: > Thanks Tom > > I enabled windrun in weewx , added the fields to the database.
