My station is a Davis Vantage Pro2 and it's got the correct elevation of 7300' entered (hence my low pressure reading).
Your high elevation is not a reason for low pressure if you have properly calibrated for sea-level pressure equivalence. Sure I would expect a low pressure for your location at your high elevation if you were reporting your QFE (station pressure also called Absolute pressure)...but nobody does that. We are only concerned with Sea Level pressure which is a number we reach because of your elevation adjustment.
Your 7300 feet almost matches what I see using FreeMapTools of 7329 feet.
https://www.freemaptools.com/elevation-finder.htmThat is enough to make 0.03 inHg difference. But I'm seeing a greater discrepancy than that...So being off by 29 feet is not the issue. It is just a small factor. There is something else going on.
Today my pressure is 29.72".
Today your pressure is 29.72 where? As in where did you pull that number from? Your VWS software, your Davis VP2 display? or Somewhere else? Because according to PWSweather you max for today only reached 29.56 at around 1:55AM (your time).
I have no offsets entered into anything since there is no official reporting station near me at my altitude for fine calibration.
Offsets or no offsets has nothing to do with stations near you at your altitude or not. I say this because I don't believe in any offsets in software. My recommendation is to make all those corrections and calibrations at the console which is the VP2 display console in your case.
VWS was getting pretty old, so I downloaded Weather Display software and the problem still exists.
I only see that you have uploaded to PWSweather. It would be helpful to see what happens when you upload elsewhere. I would recommend uploading to Weather Underground as a comparison. Helps to see if a site is manipulating your data or not.
I'm curious to hear you take a reading from 3 places at the same time and report what you see...
VP2 display console pressure reading:
PWSweather pressure: (mention which software uploaded; VWS or Weather-Display)
WeatherForYou pressure:
Weather Underground pressure: (yeah I threw this in as 4th comparison that would help, and mention which software uploaded).
It's reporting the corrected value to VWS as well as Weather Display and I Wire Sharked the packet it's sending and it's also sending the same elevation corrected value.
There's something going on with PWS Weather that's not occurring with WeatherForYou.
It would be interesting to see if VWS uploading to PWSweather is different than Weather-Display uploading to PWSweather. I think you mentioned you tried this and it didn't make a difference. But I'm not clear now from reading what you wrote if that is what you are saying. Just trying to see if the issue with PWSweather is there with both software. But it would be important to know how each software is getting the data. Meaning how is VWS getting data? Via USB logger? And when you configured Weather-Display did you then also use the same USB logger or is it pulling data from some other means?
I'm also wondering what firmware your console and logger are running?
And lastly ...just to be sure in VWS Calibration you have Barometer Gain and Offset set to 1.00 and 0.00 respectively?
