Hi
Using the Rest API I get a reading of 842.8mb which translates to 24.8907 in/HG. I have a second, inexpensive weather station that validates this is the correct reading. However, when I open up the SmartWeather app on my iPad it tells me the pressure at my house is 30.34 inHg.
On the other hand, the temperature data exactly matches between the rest api and the app so I know the app is up to date in the data it is reporting.
Thanks
