Hi. I’m using the example app on the tags (two of them). Since I was interested in very high accuracy (at least within the unit, ie if I move it from place to place it shows the change), I installed RuuviTag Scanner from https://lab.ruuvi.com/android-app/ since the screenshot shows decimals in use, unlike the default weather page.
However, in practice the app seems to show ,00 values for both of my tags(eg 995,00 and 996,00), any idea why? I found that from some API description that the tag itself should output the pressure in single pascals instead of hehtopascals.
Any ideas besides RuuviTag Scanner of how I could read the values more directly.
Or is the rounding just indicative that even though RuuviTag technically can output single pascal differences in numbers, the sensor itself only works in bigger steps and has roughly accuracy of 100 pascals or so?
Update (since I didn’t post this right away). Now both show 950,56 hPa (=95056 pascals) which should be wrong because one is outside the house and one is inside the house, and there should be at least a couple pascals difference. Again, is this indicative that the real sensitivity of the sensor is more like around 100 pascals than 1 pascal?
