No Commas

There are a set of tags where the decimal comma has been replaced with a full stop, where necessary, for use with gauges etc which do not like the commas. They all correspond to the same tag with 'RC' removed. 

<#RCdew> <#RCheatindex> <#RChum> <#RCinhum> <#RCintemp> <#RCpress> <#RCpressTH>

<#RCwchill> <#RCwgust> <#RCwgustTM> <#RCwspeed>

Parameters

Most date and/or time tags have an optional 'format' parameter, e.g: <#YearTempHT format=hh:nn>. This allows you to override the default display format for that item, using the format specifiers in the table below. Note that if your format has any spaces in it, you must enclose it in double quotes, thus: <#YearTempHT format="dd mm">. Note also that you can specify date formatting to times and vice versa, but this will not always yield a sensible result.

SpecifierDisplays
c Displays the date using the format given by the Windows Short Date format, followed by the time using the format given by the Windows Long Time format. The time is not displayed if the date-time value indicates midnight precisely.
d Displays the day as a number without a leading zero (1-31).
dd Displays the day as a number with a leading zero (01-31).

Cumulus Webtags available for Beta Version 1.9.3 Build 1058

Date and Time

WebtagPurpose
<#metdate> The current meteorological date. If using a start time of midnight for the meteorological day then this will be the same as the current date. If using a 9am rollover, then between midnight and 9am the <#metdate> will be the previous calendar day.
<#metdateyesterday>> The previous meteorological date. If using a start time of midnight for the meteorological day then this will be the same as yesterday. If using a 9am rollover, then between midnight and 9am the <#metdateyesterday> will be the calendar day before that returned by yesterday.
<#yesterday> Yesterdays date
<#DaysSince30Dec1899> Day count which gives whole and fractional part. Example: 41250.6523310301

History

There are a set of tags for 'Recent Historical Data', giving data values from 1 minute ago, up to 1 week ago in 1 minute intervals.

You specify how old you want the value to be by using parameters on the webtags for the number of days, hours, and minutes. For example, <#RecentOutsideTemp m=1> will give the temperature one minute ago, <#RecentOutsideTemp h=1> will give the temperature one hour ago as will <#RecentOutsideTemp m=60>, and <#RecentOutsideTemp d=1> will give the temperature one day ago. <#RecentOutsideTemp d=1 h=1 m=1> will give the temperature one day, one hour and one minute ago. All values supplied for parameters must be whole numbers.

Webtag Purpose
<#RecentOutsideTemp> Outside Temperature
<#RecentWindSpeed> Wind Speed
<#RecentWindGust> Wind Gust
<#RecentWindLatest> Wind Latest. Note: Wind 'Speed', 'Gust' and 'Latest' have the usual Cumulus meanings
<#RecentWindDir> Wind Direction (instantaneous)
<#RecentWindAvgDir> Wind Direction (average)
<#RecentWindChill> Wind Chill
<#RecentDewPoint> Dew Point
<#RecentHeatIndex> Heat Index
<#RecentHumidity> Relative Humidity
<#RecentPressure> Sea-level Pressure
<#RecentRainToday> Today's rain
<#RecentSolarRad> Solar Radiation
<#RecentUV> UV Index

Monthly All Time Records

There are a set of tags for monthly all-time highs and lows, in other words the highest and lowest values for a particular month of the year. For example, the highest ever temperature in July. Each Value tag has an optional parameter "mon=N" where N is the month of the year that you want the value for from 1 to 12 (January=1 and so on). For example, <#ByMonthTempH mon=7> will give you the highest ever temperature in July.

To supply more than one parameter, separate them with spaces, e.g. <#ByMonthTempHT mon=7 format=hh:nn>
