Is there anyway Meteobridge can determine Pressure trend?

can the "deltaxx" selector be used with Pressure?

Works for me.

Code: Select all

      <tr><td>Delta Pressure</td>
          <td>[thb0seapress-delta30=inHg.2:--] inHg</td>
          <td>[thb0seapress-delta1h=inHg.2:--] inHg</td>
          <td>[thb0seapress-delta60=inHg.2:--] inHg</td></tr>
Mousing over "Indoor press" / "Indoor seapress" on the Live Data tab I did realize (on the second try) that I needed two decimal places to see results.

Sorry, I meant by way of increasing or decreasing value, not the real pressure.

so as the wiki says
For sensors delivering cumulated values like "rain0total" and "sol0evo" the following selectors are defined:

sum1, sum2, sum3, ..., sum60, sum1h, sum2h, sum3h, ..., sum24h: selects summarized delta values from the last one to 60 minutes or one to 24 hours. This is useful to get amount of total rain in a certain time frame: "rain0total-sum60" is rainfall in mm of last 60 minutes.
delta1, delta2, delta3, ..., delta60, delta1h, delta2h, delta3h, ..., delta24h: selects difference between current value and value from one to 60 minutes or one to 24 hours ago. A positive number shows that value has increased, a negative number indicates the value has decreased. This is useful to do trend analysis over various time spans.
does this show a positive or negative value or the actual pressure?

As shown in the screen shot the Delta Pressure is 0.02inHg or 0.04inHg for the codes

Code: Select all

[thb0seapress-delta30=inHg.2:--]
[thb0seapress-delta1h=inHg.2:--]
[thb0seapress-delta60=inHg.2:--]
Try it and see what you get. For a test the screen shot columns are not correct for the "Delta Pressure" The columns are as the code shows delta30, delta1h and delta60. I wanted to see if delta60 and delta1h are the same.

Have you looked at Convertor "barotrend" or "enbarotrend"?

Thanks. I didnt see that... enbarotrend should fit the one I need.
