DRoberts,
I think I've managed to confuse you. Your barometer was not high before. You were probably spot on. I think the part that confused you is when I said your CWOP barometer was too high. That just means that the Altimeter pressure was too high....but this was a fault of the WiFi Logger not your calibration on your console. Now that the WiFi Logger has a new firmware you need to upgrade the firmware to this new version.
Using this menu item in the WiFi Logger:
https://www.wxforum.net/index.php?topic=34312.msg370329#msg370329After you do that your Altimeter pressure would have been automatically corrected. Only CWOP needs Altimeter pressure and it wasn't being provided.
I mentioned that you later calibrate to KHLC but you need to calibrate the console with the Sea Level Pressure numbers not the first number you see which is Altimeter.

Also you'll notice that Sea Level Pressure is report in mb and not inHg. Only Altimeter gets reported by the METAR in inHg. So there are two thing you can do to use the METAR Sea Level Pressure.
1- You can temporarily change your console to display the barometer in hPa (hectopascals) which is the same as mb (millibar) that you see in the METAR. I like this method because dealing with hPa for calibration is more precise. Later after you are calibrated if you prefer to see inHg you just switch the console to show you inHg.
2- You can convert what you see in the METAR for Sea Level Pressure to inHg using a number of websites...this one is just as good as any other:
https://www.convertunits.com/from/hpa/to/inhgThis site converts either way back and forth.
Then you can know what inHg to enter into your console for calibration. But this method is less precise.
* It isn't the hPa is more precise it is that when you use hPa consoles tend to use one decimal place for hPa and they use 2 decimal places for inHg and because of the conversion hPa is more precise with just one decimal place. If inHg was used with 3 decimal places well then it would be more precise than hPa that is expressed with 1 decimal place. Forget this technicality. You don't need to know this. This is just here for those that want to know more. Put another way 0.1 hPa = 0.003 inHg. So if you enact a change of 0.01 inHg then you've actually changed hPa by 0.3. So it is more precise to use hPa.
