Altitude correction for air pressure display on own sensors #55

Open tom-r opened 4 years ago

tom-r commented 4 years ago

My own sensor reads and shows e.g. 909.654 hPa as air pressure. As I'm living on 980m above sea level this is unusable, to compare with official pressure readings (it should show something like 1023.9hPa) ... So I kindly ask for an attribute to (manually) input the altitude above sea level (-->980) and a calculated correction of the air pressure.

Maybe, we're going to add this feature in the future, indeed thanks for the feature request!

wiki link for the formula incl. temperature correction:

German version of this wiki is more detailed. The "Deutscher Wetterdienst" (equivalent to NOAA) suggests : barometric_formula
