Is this trend or change in pressure relative to the last hour or last 24 hours?

I am posted the change for the last hour, in this example, -0.02 InHg.

When I look at the Yowindow display, it shows -> or steady.

Am I missing something?

Thank you in advance.

YoWindow indicates pressure rise/fall if pressure has changed during an hour more than 0.233 hPa
Probably this is the case.
As fas as I see you are providing the pressure trend correctly.
How much is 0.02" merc in hPa? :)

Thanks Reinhart,
it's 0.6772 hectopascals
There must be something wrong with WUHU -> YoWindow communication.
Heath, is the problem still there?

Par,

I am afraid that there is still a problem.

With:

<pressure value="30.14" trend="0.23" unit="inchMerc"/>

The pressure remains steady. 0.23, that is 7.79 Hpa (InHg * 33.86388158 = Hpa). Lesser values (<0.23) will also cause a steady pressure.

It is necessary to have:

<pressure value="30.14" trend="0.24" unit="inchMerc"/>

That would be an equivalent HPA of 8.127, In order for the trend to show a rising pressure trend.

If you do correct this issue for PWS, can you please give the pressure on the main screen a 0.01 precision when English units are used?

Thank you.
