Re: Pressure Trend
See the Wiki, search on <#presstrend>.
Pressure (Tags)
<#press>: The sea level pressure
<#presstrendval>: The average rate of pressure change over the last three hours. Trend = (pressure_now - pressure_3hrs_ago) / 3 (Fixed from version 1.7.7 5th March 2008)
<#presstrend>: The pressure trend in words - values can be set in the 'strings.ini' file
<#presstrendenglish>: a singe word description for the pressure trend - Rising/Falling/Steady (for use by HTML, javascript etc, values can't be changed). From version 1.8.8 1st December 2009
<#PressChangeLast3Hours>: Badge vMx.png Available from version 3.11.1, Total Pressure Change since 3 hours ago
<#altimeterpressure>: Altimeter pressure. Pressure corrected to sea level using the station's altitude only. Same as sea-level pressure for non-Davis stations.

Re: Pressure Trend
I followed the Wiki years back, that's why I am here..
<#presstrend> has always worked; ie "Falling Quickly"
But it doesn't work anymore, it just returns "Pressure Trend"

Re: Pressure Trend
My only thought is you have overridden the default strings in a copy of strings.ini?

Lazyness? I'm here to report something that was working fine, but now it isn't. Spare me the lecture.

Re: Pressure Trend
No idea what is going on, but the api call still returns:
Even after updating to the latest version.
I don't use a strings.ini either, so i have no idea.

Re: Pressure Trend
OK, with that capitalisation I have found it.
Do you have "Cumulus pressure names" enabled in Station Settings => Common Options
The Davis does not provide pressure trend strings. But if your station type is set to Davis VP2, that should automatically use the Cumulus pressure names no matter what that setting value.

That's something I have never enabled, as I haven't needed to.

Re: Pressure Trend
If you are using the VP2 or WLL station then you should not have to, that will override it.
I'll have to setup my test rig as a VP2 and look at this (the WLL is working OK), that bit code hasn't been changed afaik since Steve stopped developing it...
