So you have run WeeWX directly and are seeing all three WeeWX pressure fields. WeeWX field pressure is matching what is on your console exactly. Fields altitude and barometer are 'in the 32s'. By my rough calculations an absolute pressure of 29.9inHg at 2300ft gives a barometer value of about 32.5. So on the face of it it would appear that the driver is providing data (whether it is right or wrong) in field pressure and WeeWX is calculating fields barometer and altimeter as expected.

The 28xx driver takes the pressure value displayed on the station hardware and feeds that to WeeWX as the WeeWX field named pressure (after which WeeWX calculates fields barometer and altitude). Do you want the driver to instead take that pressure value displayed on the station hardware and feed that to WeeWX as the WeeWX field named barometer (after which WeeWX calculates fields pressure and altitude)? That can be done but it requires modification of the driver code, I would not being doing that lightly, someone did not roll a dice and randomly decide to put the pressure value from the 2813 in field pressure, it was done for a reason. I was looking for a 2813 manual and the only manual I could find was for a WS-2813U-IT weather station. On page 14 it talks about setting a 'Relative value pressure reference setting' based on a value from a weather service, airport etc. Is that your station and have you set that correctly or if not your station is there a similar setting?
