Ecowitt-Client pressure calibration problem

[Wojtek Jakieła]

Hello.

I have problem with pressure calibration.

I'm using Ecowitt-Client. When i put altitude 2m (above the ground) i see ~980mbar, when i put altitude 427m (above the sea) i see ~1021mbar. Correct pressure is ~1016mbar.

How can I calibrate this?

I recommend that you calibrate at the console (GW1000) and not with WeeWX. 

Go to WS View and enter 49.8 hPa for Relative Offset. This corresponds to 427 m

Then adjust your Absolute value to cause what shows up as relative pressure to match METAR.
