Re: [weewx-user] Davis Vantage Pro2 Wind Direction Issue

[Peter_F]

Thanks for the tip Thomas.  Yes, it is a wireless VP2.  I had tried moving 
the console before but I gave it another go and it made no difference.  I 
do get good signal strength with rxCheckPercent close to 100%.

Re: [weewx-user] Davis Vantage Pro2 Wind Direction Issue

[Thomas Keffer]

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?

[weewx-user] Davis Vantage Pro2 Wind Direction Issue

[Peter_F]

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.

Anyone have any ideas?

- Peter
