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). A few weeks ago I noticed on the console that the Wind Direction was locked onto due south (180 degrees). Wind Speed is working OK. The Envoy was showing the same on WeeWX. The Console and Envoy have an offset configured for 180 degrees because the anemometer is pointing South instead of North because I want the solar panels pointing North as I am in the Southern Hemisphere. After checking connections, etc and finding no issues, I bit the bullet and bought a new anemometer. To my disappointment, the problem persisted with the new anemometer. I spoke to Davis and they said it must be the Transmitter Board so I reluctantly purchased a new one from them. I have installed it and the problem STILL persists. After ringing Davis again, they tried to blame the Raspberry Pi which makes no sense as the Console is not connected to the RPi. Since then I have tried various things - changing Transmitter channel, Firmware updates, unplugging all other sensors from the ISS - but to no avail. Very occasionally the Wind Direction does work, but not for very long. Other knowledgeable people I have spoken to (no knowledge about Davis Weather Stations though) said it's probably electrical interference. All the answers I can find is either a busted anemometer or a broken wire. I have replaced both the anemometer (comes with new cable) and also the Transmitter. There's not much else to replace. When I ordered the new anemometer, I gave the old one to a friend who is interested in building his own Weather Station from discrete sensors and micro-controllers. He was interested in pulling it apart and possibly fixing it. He said the anemometer works no problems. I'm at my wit's end. I have thrown a few hundred AU$ at this and have got nowhere. To really rub it in, my Envoy decided to die the other day. I don't have the cash to replace that so I have moved the data logger to the console and now running WeeWX off that.
