JD said that he “suspects” that would be the right change. It would help if you tested it, but be prepared for it not to work or break the driver. Save the original version of the file, and restart weewx after changing it in order to load the new version. The location of the driver can

Re: [weewx-user] Re: Mismatch Between Hardware and weeWX Data

well if it is hard coded for pressure then the station adjustment made by the OP should be to set his station to a known sea level pressure and subtract a correction for altitude (2.6 for 2300 ft I think) and all should then be ok On Monday, 17 February 2020 07:09:35 UTC+2, ln77 wrote: > >

Setting those that way won’t fix the problem. Those settings are hints to weewx about what to use when the weather station hardware provides multiple values. The WS28XX driver is hard-coded to interpret the data from the station as weewx “pressure,” and that is the only pressure-related datum

Re: [weewx-user] Re: Mismatch Between Hardware and weeWX Data

OK… The “pressure” that your station is displaying is what it should be displaying: the ambient air pressure, correct for your altitude. In weewx, this is called “barometer” because that is what weather stations report for barometric pressure. “Altimeter” is basically the same thing; there

Re: [weewx-user] Re: Mismatch Between Hardware and weeWX Data

It is likely that I am mis-using the terms altimeter, barometer, and pressure. I'll clarify what I mean here. What I previously defined as 'correct' pressure is that the pressure reported by my station (LaCrosse WS-2813U-IT) matches the National Weather Service barometer reading (

Re: [weewx-user] Re: Mismatch Between Hardware and weeWX Data

What I am defining as 'correct' pressure is the barometer value that matches the local reading from the National Weather Service (NWS) for my area. In other words, the pressure on my weather station (LaCrosse WS-2813U-IT) matches what the NWS is reporting as Barometer (

Re: [weewx-user] Re: Mismatch Between Hardware and weeWX Data

I would expet you to be reporting barometer = sea level pressure which is pressure adjusted for temperature and altitudebecause weather stations always report sea level pressures. Is what you call 'correct' pressure the raw pressure of the instrument or a pressure which you have set. Does the

If you have a LaCrosse WS28xx station then according to the hardware guide the station outputs PRESSURE in weewx terminology - regardless of what LaCrosse call it - and weewx should calculate barometer and altimeter settings. If pressure is incorrect then it can be adjusted as you specified -
