      Last week I sent my s9 baro back in Finland to fix the barometer that registered pressure between 8 to 11 hPa higher than weather station around me at the same height above sea level.
      Still waiting for an official response by Suunto assistance but I think some sensors are just defective.

        @zzmike76 nope. Suunto watches show sea level since they do know the altitude. You can add that to raspi I can help you convert it if you like

        I would check the local weather station for his sea level pressure

          @General_Witt I pressume you checked the weather station sea level pressure not pressure. Weather stations might and will report both

            You should be able to see the difference if you manually set reference altitude

              Of course. 3 different government ones. In one case I hiked till I was literally 1 meter away from the sensors. Still 8-9 hPa difference.

                @General_Witt very strange. WTF. Did you get the new unit back ?

                  Was the altitude correct?

                    @General_Witt @sartoric the altitude is correct in the watch (372 meters), but pressure always differs by at least 20/30 hPa, i guess the sensor has some issues

                      Hey @zzmike76 may I know the location and the pressure raspi and S9 reports. I can check online for you

                        @zzmike76 30hpa is a completly defective device. I do insist that one is looking at a different value.

                          @zzmike76 on the ambit3 you can go into a service menu, to show the absolut pressure. (Maybe you can check that too on the S9)
                          When I got the watch, it was absolut perfect calibrated. When I first time did a hike, with Baro Mode altitude, the sea level pressure difference was exactly the difference of the weather change in this time of the hike. But the absolut pressure is spot on.

                            I’m still in “received” status. They got the watch wednesday, I’m waiting for some response these days.
                            Anyway I tried both manual and auto altitude calibration with no avail.

                                        So for your place here is the current day value and prediction of SEALEVEL pressure not absolute pressure.
