Re: [weewx-user] Show Relative Pressure instead of Absolute Pressure

I think I understand what you are asking. By default, the Fine Offset driver reports only absolute pressure. WeeWX uses this, as well as altitude and temperature, to calculate "altimeter" and "barometer". Relative pressure is not emitted by the driver at all. If for some reason you really want

Re: [weewx-user] Show Relative Pressure instead of Absolute Pressure

I believe that with your station absolute pressure is the pressure as seen at your station. relative pressure on your station you will have manually set in your station by adjusting for altitude (and will usually be a higher value). The station only outputs the absolute value to weewx - and

Re: [weewx-user] Show Relative Pressure instead of Absolute Pressure

Thanks for your reply Thomas, I had read this article and that's why I changed the names of sensors to try something. With relative pressure I want to say the absolute pressure plus an offset. (for example, the absolute pressure show 950hPa, and the relative pressure show 1011hPa, both in the

Re: [weewx-user] Show Relative Pressure instead of Absolute Pressure

Take a look at the Wiki article *Barometer, pressure, and altimeter *, and see if that answers your question. If not, perhaps you can tell us what you mean by "relative pressure." -t On Sun, Sep 22, 2019 at 5:43 AM Miguel

[weewx-user] Show Relative Pressure instead of Absolute Pressure

Hi, I have recently installed WeeWX v3.9.2 in my Raspberry Pi 2, with the PCE-FWS 20. All is working, but this station has Absolute and Relative pressure, and in the section Barometer, WeeWX show me the Absolute pressure and I want to see the Relative pressure. I have tried changing names of
