Sealevel pressure calculation seems to be incorrect

1st of all, thanks for this amazing application. (I m using Cumulus MX release - v3.0.0 build 3036)

I have noticed, that there seems to be some error while calculating sea level pressure. Program shows exactly 10 hPa more, than it should.

I have WS-0101 meteostation (http://www.conrad.com/ce/en/product/672 ... er-Station).

My settings:
Station type: Fine offset
Altitude 300 meters exactly.

Readings at the meteostation (at the moment of writing)
absolute pressure: 968.5
temperature 3.2 celsius
==> this shall give 1005.0 hPa at 300 m level of altitude. Instead Cumulus MX reports 1015.0

I had to set altitude in settings to 400 m (100 m more) to get the sea level pressure correct..

Is it a bug in algorithm or I m missing some settings?

Cumulus doesn't calculate the sea level pressure, it reads it from the station. You need to set your relative pressure on the console (and then restart Cumulus). There should be instructions in the weather station manual.

Ok, thanks for the answer. I have read the link before posting, non of the points applied, but I figured out why.. (my stupidity of course:)

I adjusted the relative pressure on the meteostation, but cumulus doesn t read the data correctly until restart of the application (meanwhile I also adjusted the altitude, so I thought it might be involved somehow).

So for everyone - if you adjust relative pressure on meteostation, you need to restart cumulus to make it read the data correctly..

Thanks!
