The get-metar-conditions-inc.php script is used to parse that (for both the dashboard and the wxmetar.php page). It may be that some funky METAR codes are emitted by the AUTO station submission. I'd need to see that raw METAR string when the issue is present to diagnose further.The manual for the hp2003n sensor on page 2 has a (typical, not guaranteed ) long term drift of +/-2mbar after 1 year.Thanks for the specs!. I always wondering how our sensors performed and I have to say, I winced more than a few times in reading the numbers.
If we consider this drift linear in time ( it is not specified, so it is only a supposition ) we have a drift of +/-3mbar after 18 months and a 0.3mbar variation for the height difference.
So the variation you measured seems to be within specs/to be expected.
This may mean that these 'things' do not stay calibrated for long.
P.S.
For comparison the ( high resolution/stability ) bmp390 ( gszlag is referring to in this post ) has a drift of only +/-0.16hPa after 12 months )
