Sounds like you're having a bad week! I assume this is a wireless VP2? I once had a similar experience that was cured by moving the console. The RF reception between ISS and console was so poor it resulted in a wind direction that was wrong, or didn't change.
As an experiment, can you try moving the console closer? -tk On Thu, Aug 15, 2019 at 7:01 PM Peter_F <peter.fere...@gmail.com> wrote: > This may be the wrong forum for this but I have Googled this to death and > no apparent answer. > > I have had my Davis Vantage Pro2 for over four years and have had no > issues (Console on my desk and an Envoy with data logger plugged into RPi > running WeeWX).
