Trend of ambient pressure

Tak79 over 4 years ago

Hi,

I want to display the ambient pressure with an icon that will indicate the trend.

In order to do this I have to compare with the latest from PressureHistory?

Thanks

Hi,

It is how I do, I compare the first and the last entry with SensorHistory.

When I try to display Sensor.getInfo() .pressure I have an error that the watchface doesn't have permission to use Sensor, even in manifest.xml the Sensor is there

Sensor is only available to watchface apps when running in the background.

That is why I wrote SensorHistory ans not sensor.

A watchface can deal with SensorHistory

I'm trying to find out what the pressure was three hours ago.

An error occurs when trying to retrieve data.

What am I doing wrong?

if ((Toybox has :SensorHistory) && (Toybox.SensorHistory has :getPressureHistory)) {
    var p = new Time.Duration(10800);
    var previuosPressure = Toybox.SensorHistory.getPressureHistory({:period => p, :order => 1}); // An error occurs
}

Hi,

Does someone can share the codes to make like the Suunto : 3 and 6 hours history trend and display only if the difference is >2 hPa/3hours.

Best regards
