==Current Conditions==


The web tags/token shown here are mainly determined by which appear on "Now" page (index.htm).
Cumulus software makes current values available for a standard range of sensors where the same web tags apply across a range of weather station models.
Rainfall this month and this year are included here for consistency with supplied web templates (indexT.htm, thismonthT.htm, and thisyearT.htm) and with the dashboard 'Now' part of the Cumulus MX user; although you might expect to find them listed in tables for this month and this year, those web pages do not show these derivatives.
 
Cumulus 1 and MX offer current values from some extra temperature and relative humidity sensors (see [[Extra temperatures]]) frm particular weather station models  (from Davis and Oregon Scientific).
 
Recently, MX has been developed to support further extra sensors (see [[Extra Sensor Files]] page for full list of fields) and web tags have been added to support current values only.
 
==== Feels Like ====
 
Feels like temperature was first made available, just for current conditions at MX version 3.5.4.  In version 3.6.0. it was extended to add max/min for each day, each month, each year, and all time. In version 3.6.11 it was added to recent history.
 
 
The figures quoted for this derivative vary between versions:
* The first formula was used from MX version 3.5.4 (25 Apr 2020) build 3075 until version 3.6.7 (4 June 2020) build 3083
* The second formula, which was coded incorrectly, and so gave strange results, applied in versions 3.6.8 to 3.6.9 (build 3084, 3085)
* The third, and hopefully final, formula applies from version 3.6.10 (build 3086).
 
A php script for adding feels like as calculated in version 3.6.10 to any standard log line created either without feels like, or with an older (now incorrect) calculation, can be downloaded from [https://cumulus.hosiene.co.uk/viewtopic.php?f=18&t=18096 Create Missing topic on support forum]. Obviously, this calculates from the small sub-set of current conditions that have been logged, and is not as accurate at deriving maximum and minimum as derivation made as each reading is processed by MX (so including all current conditions).
 
The [[Calculate_Missing_Values#CreateMissing.exe| Create Missing utility]] will not correct the older (incorrectly calculated) figures, but will add Feels Like temperature values to any standard log line created by Cumulus 1, by MX prior to release 3.5.4, or if you have imported lines into the log from an external source.
 
===Standard sensors===
 
The web tags shown here are mainly determined by which appeared on the original "Now" legacy web page (index.htm).
 
Consequently, the totals for Rainfall this month, and this year, are included here for consistency with supplied web templates (indexT.htm, thismonthT.htm, and thisyearT.htm) and with the dashboard 'Now' part of the Cumulus MX user; although you might expect to find them listed in tables for this month and this year, those web pages do not show these derivatives.
   
   
Those listed here cover both measurements obtained from a weather station (like air temperature, wind speed and direction, humidity and barometric pressure); and all the derived values (like humidex, feels like, apparent temperature, wind chill and heat index).

Note however, that the derived values calculated for Cumulus 1 and for MX may not agree, see derived value section within Recent History tags section for examples.

Obviously, this calculates from the small sub-set of current conditions that have been logged, and is not as accurate at deriving maximum and minimum as derivation made as each reading is processed by MX (so including all current conditions).
Some tags are only available for certain builds, if the tables below do not say which releases they apply to, see general tip at top of page to check for the build you are using. In particular Cumulus 1 has fewer channels available in its earlier versions, and the final legacy software version 1.9.4 offers just 42 of the 62 extra sensor web tags available in MX.


==Extra Sensors==
The extra sensors functionality in Cumulus only supports processing for current spot values as read from the sensors, the only processing is to convert the units ready for output, so only current conditions can be reported in web tags.


===Extra Sensors Davis (and a few others)===
Periodically spot extra sensor values are logged, see the [[Extra_Sensor_Files]] page for information about log files from where you can extract the past spot values.


These web tags hold current values for additional sensors supported by Cumulus. Most of the tags in this section relate to Davis stations, but not exclusively.
===Extra Sensors: Davis Oregon Scientific WMR928, WR100/200 ===


Some tags are only available for certain builds, see general tip at top of page to check for the build you are using. In particular Cumulus 1 has fewer channels available.
These web tags hold current values for additional sensors supported by Cumulus 1 and MX.  


There are no web tags for past values from extra sensors, see the [[Extra_Sensor_Files]] page for information about log files from where you can extract those values.

Ecowitt stations are sold under other names depending on nation,  e.g. Ambient in USA, Froggit in central Europe, so Ecowitt is used as a generic name in same way as Fine Offset is used elsewhere in this article.
 
==Recent History==
 
There are a set of web tags for 'recent historical data', based on an array stored by Cumulus giving data values from 1 minute ago, up to 1 week ago, in 1 minute intervals. As Cumulus runs it will add the latest values to the array with full resolution, and shift existing values along so those older than 7 days fall off. 
*The input modification parameters available are listed at [[Webtags/Parameters#Input Modification Parameters for Recent History]].
**To save you looking up the details, these input parameters specify how many minutes ago is required. Instead of entering a very large number for minutes, you can include separate input parameters for days, hours, and minutes, ago.
**Examples appear in the table below, with explanations
 
Following the table giving the tag names actually available, there is a section on how to derive a few more weather derivatives using a combination of the tag names shown.
 
 
===Warning when Daylight Saving Time starts or ends===
 
Note that Cumulus uses current time, read from the computer, to determine which array element it stores each value in.
 
Hence ''when clocks go back'' the value stored for winter time overwrites the value previously stored for same time during summer time for the relevant repeating hour.
 
Hence even if you use 10am for your rollover time in summer, you will not have access to a whole hour worth of data when the clocks change
* ''when the clocks go back'', one hour has been overwritten; or
* ''when the clocks go forward'', one hour in the array simply does not exist.
 
=== Table of Recent History web tags available ===
 
 
[[#No_Commas]] versions of the array are available for use in script. If you use MX, the tag names in this table can take a [[Webtags/Parameters#Output Modification Parameter for Removing Commas|rc=y]] parameter.

=== Other weather derivatives ===
===Extra Sensors: Ecowitt WH45 CO₂ sensor===


Although Humidex, 'Apparent Temperature', 'Feels Like temperature' and others listed in Current Conditions section, are not available at all versions, they can be calculated in a script from recent 'outside temperature', 'wind speed', and 'relative humidity' values (using the same time selection for all). There are other derivatives that can be calculated similarly from a set of simultaneous values. Note that Cumulus 1 and MX do not always use identical formula, and although MX added Feels Like it has changed the formula a few times.
[[File:Badge vMx.png]] Unless otherwise indicated these web tags become available from release 3.9.5.


The relevant formulae using JavaScript, adjust for other languages, for some of these are shown below:

[[File:Badge vMx.png]] Please see release announcements for when individual web tags became available


Note this apparent temperature formula uses Celsius for temperature and '''metres per second''' for wind speed. You will need to do the appropriate conversions from the quoted recent history tags if you use different units.  The Australian Apparent temperature formula is same for Cumulus 1 and MX:
This section applies only to those using Ecowitt GW1000 (Froggit DS1500) an interface unit that picks up various external sensors and sends the data via an application programming interface to MX which then generates the following web tags:


var actualVaporPress = <#RecentHumidity h=3>/100) * 6.105 * Math.exp(17.27 * <#RecentOutsideTemp h=3>) / (237.7 + parseFloat(<#RecentOutsideTemp h=3>))));

Feels Like was implemented as a recent history web tag at version 3.6.11 (see [[#Feels_Like|Feels Like section below Current condition web tags]]) for the gradual introduction of feels like elsewhere. For earlier MX versions, and if you are using Cumulus 1, you can calculate it:


The formulas below use Celsius for temperature and '''km per hour''' for wind speed. Again, you will need to do the appropriate conversions from the quoted recent history tags if you use different units.

|<#LightningDistance>


Calculation from recent history tags is much more complicated because there are 3 different calculations: Feels Like reports exactly same as wind chill for temperatures '''below''' 10°C or 50°F so the WC here should equal <#RecentWindChill h=3>:
|{{Version badge 1}} Not available in Cumulus 1.
<pre>if(<#RecentWindSpeed h=3> < 4.828) WC =  <#RecentOutsideTemp h=3>;
else{
wind_pow =  Math.pow(<#RecentWindSpeed h=3>, 0.16);
WC = (13.12 + 0.1625 * <#RecentOutsideTemp h=3>) - (11.37 * wind_pow) + (0.3965 * <#RecentOutsideTemp h=3> * wind_pow);// Brackets used to ensure "+" is interpreted as addition not concatenation
} </pre>


For temperatures '''above''' 20°C or 68°F Feels Like uses a different way to calculate apparent temperature that it uses at these higher temperatures (this formula only used for 3.6.10 onwards):
[[File:Badge vMx.png]] see release announcements for version availability
<pre>var actualVaporPress = <#RecentHumidity h=3>/100) * 6.112* Math.exp((17.62 * <#RecentOutsideTemp h=3>)/(243.12 + <#RecentOutsideTemp h=3>)) / 10.0;  // Not same as at build 3084
/* uses kilometres per hour for wind speed */

==Today==
[[File:Badge vMx.png]] see release announcements for version availability


Cumulus MX provides more web tags than the original (now legacy) Cumulus software. Please see individual entries for what is available in the flavour you are using. Where known, the actual release that introduces a particular web tag is indicated, but if you are using an old release please [[Webtags#GENERAL_TIP|see here]] for how to check which web tags are available.
Date and Time of last strike (default without output parameters is locale's short time format e.g. 18:02 or 6:02 pm, without date, but tag accepts both date and time output parameters). Returns '----' if you don't have sensor or there has not been a strike since the sensor was installed. (GW1000 api returns FFFF FFFF seconds after midnight on 01 Jan 1970, which translates to 07/02/2106 06:28:15, so MX translates that to '----')

|<#LightningStrikesToday>


===Weather Diary===
|{{Version badge 1}} Not available in Cumulus 1.


Meteorologists report snowfall, and snow days, on a calendar day basis (i.e. midnight to midnight), and Cumulus software enables this by allowing you to declare the '''SnowDepthHour''' time (in [[Cumulus.ini#Section:_Station]], default is 9 a.m. for Cumulus 1, and default is midnight for MX).
[[File:Badge vMx.png]] see release announcements for version availability


However, Cumulus software also allows you to choose one of 3 meteorological days:
Number of strikes since midnight, default 0
# starting at 9:00 am, based on winter time, so switching to 10:00 during Daylight Saving (summer) time, or
|-
# starting at 9:00 am, all year round, or
|<#UserTemp1>
# aligned with calendar days.


For MX users who choose options 1, and 2, with the MX default for snow depth, there is a mismatch between the times for the web tags in the two tables below. The mismatch will also cause problems if you use any End of Day actions, such as using web tags for either a [[MX_Administrative_Interface#Another_daily_summary_table|custom database table update]], or for [[Cumulus.ini#MQTT|MQTT messages]]. For the original Cumulus 1 software, only one web tag is available, but by default this has a mismatch if you use midnight-midnight days; this was intentional as Steve Loft assumed you would record the snow depth at 9 a.m. rather than midnight even if your rollover is at midnight!
|{{Version badge 1}} Not available in Cumulus 1.


An alternative approach is to use a script to read the [[Weather Diary]], so you know that your output is for the right day.
[[File:Badge vMx.png]] see release announcements for version availability


This first table lists all the web tags available for reporting what is recorded in the weather diary. Just to be clear, the web tags shown below, will report data for previous day if the current time is before the snow depth hour setting, and report data for the current day if the current time matches the snow depth hour or is later.

|<#snowdepth>
|Meteorologists report snow depth in cm, so this is default unit for Cumulus.


If there is no entry in Weather Diary for the day explained above, reports zero.


{{Version badge 1}} Input and output is always as integer. Available from very early builds, weather diary input amended from version 1.8.6 14th April 2009 to allow units to be specified on diary edit screen. If you choose to enter as whole millimetres,  you can use JavaScript (or another script language) on your web page to divide the web tag by 10 and get centimetres to 1 decimal place on output.


[[File:Badge vMx.png]] Input is to 2 decimal places. Available from version 3.1.1 - build 3054 when weather diary editor was added to MX.  MX allows output in centimetres with decimal places without any script. You can't change the units shown in admin interface, but your value can be input as inches to 2 decimal places if you ignore "cm" that is displayed in that interface.

|<#snowlying>
|{{Version badge 1}}Although this tag is not available in Cumulus 1, your web page can use a script to check if <#snowdepth> is non zero, as that means snow is lying


[[File:Badge vMx.png]] Available from version 3.1.1 - build 3054.   If there is no entry in Weather Diary for the day explained above, , this web tag returns Null. Otherwise reports 1 if tick in diary, 0 is unticked.
There are a set of web tags for 'recent historical data', based on an array stored by Cumulus giving data values from 1 minute ago, up to 1 week ago, in 1 minute intervals. As Cumulus runs it will add the latest values to the array with full resolution, and shift existing values along so those older than 7 days fall off.

**To save you looking up the details, these input parameters specify how many minutes ago is required. Instead of entering a very large number for minutes, you can include separate input parameters for days, hours, and minutes, ago.

Following the table giving the tag names actually available, there is a section on how to derive a few more weather derivatives using a combination of the tag names shown.
|}


===Today.ini===


This second table takes most of its information from the data log for today, many of these web tags are used on the supplied '''todayT.htm''' template in the "/web" folder.  If you are using MX, the today and yesterday page in the [[MX_Administrative_Interface]] shows similar information by using the [[Cumulus_MX_Local_API#Today.2FYesterday_Data|local application programming interface]].
===Warning when Daylight Saving Time starts or ends===
 
Note that Cumulus uses current time, read from the computer, to determine which array element it stores each value in.
 
Hence ''when clocks go back'' the value stored for winter time overwrites the value previously stored for same time during summer time for the relevant repeating hour.
 
Hence even if you use 10am for your rollover time in summer, you will not have access to a whole hour worth of data when the clocks change
* ''when the clocks go back'', one hour has been overwritten; or
* ''when the clocks go forward'', one hour in the array simply does not exist.
 
=== Table of Recent History web tags available ===
 


For web tags that report values that refer to a particular time of day, there is a corresponding web tag that can give the time of day, shown in same row of table below. For those that cover whole day so far, the final column contains "n/a".
[[#No_Commas]] versions of the array are available for use in script. If you use MX, the tag names in this table can take a [[Webtags/Parameters#Output Modification Parameter for Removing Commas|rc=y]] parameter.


Please note none of the time web tags can be modified by output parameters to give a date, but they can be changed from the default time format that is 'H:mm' (24 hour clock notation without leading zero for hour) for Cumulus 1 and MX. If you are using output modifiers to change how the time is reported, be careful to use ones that work for the flavour of Cumulus you are using (H and h are same for Cumulus 1, but not for MX; nn and mm are same for Cumulus 1, but not for MX).

var appTempDegC = parseFloat(<#RecentOutsideTemp h=3) + (0.33 * actualVaporPress) - (0.7 * <#RecentWindSpeed h=3>) - 4;


Note that Cumulus does not use thousand separators, so the only places a comma can be used are as a field separator or as a decimal separator. Obviously it cannot be used for both. This section is for those locales where a comma is used instead of a full stop to separate the integer and decimal parts of a number. Some computer languages like JavaScript will not accept a comma being used for this purpose, and Cumulus uses JavaScript for various tasks, as do various third party web pages.  From '''version 1.9.3''' build 1045, Cumulus 1 (and MX) has provided some current conditions web tags, some today web tags, and some recent history web tags in an alternative format where (regardless of locale) the number is always output in a format that uses a decimal point. They all correspond to the same tag with 'RC' removed.
Feels Like was implemented as a recent history web tag at version 3.6.11 (see [[#Feels_Like|Feels Like section below Current condition web tags]]) for the gradual introduction of feels like elsewhere. For earlier MX versions, and if you are using Cumulus 1, you can calculate it:


===CURRENT CONDITIONS:===
The formulas below use Celsius for temperature and '''km per hour''' for wind speed. Again, you will need to do the appropriate conversions from the quoted recent history tags if you use different units.


<#RCtemp>, <#RCdew>, <#RCheatindex>, <#RChum>, <#RCinhum>, <#RCintemp>, <#RCpress>, <#RCrfall>, <#RCrrate>, <#RCwchill>, <#RCwgust>, <#RCwspeed>, <#RCwlatest>
Calculation from recent history tags is much more complicated because there are 3 different calculations: Feels Like reports exactly same as wind chill for temperatures '''below''' 10°C or 50°F so the WC here should equal <#RecentWindChill h=3>:
 
<pre>if(<#RecentWindSpeed h=3> < 4.828) WC =  <#RecentOutsideTemp h=3>;
===TODAY:===
else{
wind_pow =  Math.pow(<#RecentWindSpeed h=3>, 0.16);
WC = (13.12 + 0.1625 * <#RecentOutsideTemp h=3>) - (11.37 * wind_pow) + (0.3965 * <#RecentOutsideTemp h=3> * wind_pow);// Brackets used to ensure "+" is interpreted as addition not concatenation
} </pre>


<#RCpressTH>,  <#RCpressTL>,  <#RCrrateTM>,  <#RCtempTH>, <#RCtempTL>, <#RCwgustTM>, <#RCdewpointTH>, <#RCdewpointTL>, <#RCwchillTL>, <#RCheatindexTH>, <#RCapptempTH>, <#RCapptempTL>
For temperatures '''above''' 20°C or 68°F Feels Like uses a different way to calculate apparent temperature that it uses at these higher temperatures (this formula only used for 3.6.10 onwards):
<pre>var actualVaporPress = <#RecentHumidity h=3>/100) * 6.112* Math.exp((17.62 * <#RecentOutsideTemp h=3>)/(243.12 + <#RecentOutsideTemp h=3>)) / 10.0;  // Not same as at build 3084
/* uses kilometres per hour for wind speed */
/* What Cumulus MX will use to calculate apparent temperature for feels like is changed very slightly */
if(<#RecentWindSpeed h=3> > 72) <#RecentWindSpeed h=3> =72;
AT= (1.04 * <#RecentOutsideTemp h=3>) + (2 * actualVaporPress) - (0.1805553 * <#RecentWindSpeed h=3>) - 2.7;</pre>


===RECENT HISTORY:===
For in-between temperatures it uses a more complicated merge of the two formulas for AT and WC as defined above:
<pre>app_temp_mult = (<#RecentOutsideTemp h=3> - 10) / 10;
wind_chill_mult = 1 - app_temp_mult;


<#RCRecentOutsideTemp>, <#RCRecentWindSpeed>, <#RCRecentWindGust>, <#RCRecentWindLatest>, <#RCRecentWindChill>, <#RCRecentDewPoint>, <#RCRecentHeatIndex>, <#RCRecentPressure>, <#RCRecentRainToday>, <#RCRecentUV>
FL= AT * app_temp_mult + WC * wind_chill_mult;</pre>


Although 'Apparent Temperature' is not included as a tag, it can be [[FAQ#What_formula_does_Cumulus_use_for_Apparent_Temperature.3F | calculated]] in a script from the RC tags for 'outside temperature', 'wind speed', and 'relative humidity' values. In php language this is <tt>$RCapptempCALC = round(<#temp> + (0.33 * (<#hum> / 100 * 6.105 * exp (17.27 * <#temp> / (237.7 + <#temp>) ))) - (0.7 * $wspeed) - 4.0, 2);</tt>.
==Today==


There are other derivatives that can be calculated similarly from a set of simultaneous values, as described below the recent history section.
Cumulus MX provides more web tags than the original (now legacy) Cumulus software.  Please see individual entries for what is available in the flavour you are using. Where known, the actual release that introduces a particular web tag is indicated, but if you are using an old release please [[Webtags#GENERAL_TIP|see here]] for how to check which web tags are available.


From '''version 3.5.4''' build 3075, all web tags (except indoor temperature <#intemp> where rc parameter not available until version 3.6.8 build 3084), that produc
===Weather Diary===
=== Heading text ===
e decimal number output now support the "'''rc=y'''" option. e.g. <tt><#tempYH rc=y></tt> will report yesterday's highest temperature using a full stop to separate decimal part where the locale would normally use a comma.


==Yesterday==
Meteorologists report snowfall, and snow days, on a calendar day basis (i.e. midnight to midnight), and Cumulus software enables this by allowing you to declare the '''SnowDepthHour''' time (in [[Cumulus.ini#Section:_Station]], default is 9 a.m. for Cumulus 1, and default is midnight for MX).


Note that the Y indicating yesterday is sometimes a prefix, sometimes a suffix (with H for High, L for Low), web tags are not named consistently!
However, Cumulus software also allows you to choose one of 3 meteorological days:
 
# starting at 9:00 am, based on winter time, so switching to 10:00 during Daylight Saving (summer) time, or
Many of these web tags are used on the supplied '''yesterdayT.htm''' template.
# starting at 9:00 am, all year round, or
# aligned with calendar days.
 
For MX users who choose options 1, and 2, with the MX default for snow depth, there is a mismatch between the times for the web tags in the two tables below. The mismatch will also cause problems if you use any End of Day actions, such as using web tags for either a [[MX_Administrative_Interface#Another_daily_summary_table|custom database table update]], or for [[Cumulus.ini#MQTT|MQTT messages]]. For the original Cumulus 1 software, only one web tag is available, but by default this has a mismatch if you use midnight-midnight days; this was intentional as Steve Loft assumed you would record the snow depth at 9 a.m. rather than midnight even if your rollover is at midnight!


If you are using MX, the today and yesterday page in the [[MX_Administrative_Interface]] shows similar information by using the [[Cumulus_MX_Local_API#Today.2FYesterday_Data|local application programming interface]].
An alternative approach is to use a script to read the [[Weather Diary]], so you know that your output is for the right day.


For web tags that refer to a particular time of day, there is a corresponding web tag that can give the time of day. Please note none of the time web tags can be modified by output parameters to give a date, but they can be changed from the default time format that is 'h:mm'.
This first table lists all the web tags available for reporting what is recorded in the weather diary. Just to be clear, the web tags shown below, will report data for previous day if the current time is before the snow depth hour setting, and report data for the current day if the current time matches the snow depth hour or is later.

|Meteorologists report snow depth in cm, so this is default unit for Cumulus.
 
If there is no entry in Weather Diary for the day explained above, reports zero.
 
{{Version badge 1}} Input and output is always as integer. Available from very early builds, weather diary input amended from version 1.8.6 14th April 2009 to allow units to be specified on diary edit screen. If you choose to enter as whole millimetres,  you can use JavaScript (or another script language) on your web page to divide the web tag by 10 and get centimetres to 1 decimal place on output.
 
[[File:Badge vMx.png]] Input is to 2 decimal places. Available from version 3.1.1 - build 3054 when weather diary editor was added to MX.  MX allows output in centimetres with decimal places without any script. You can't change the units shown in admin interface, but your value can be input as inches to 2 decimal places if you ignore "cm" that is displayed in that interface.

===Today.ini===
 
This second table takes most of its information from the data log for today, many of these web tags are used on the supplied '''todayT.htm''' template in the "/web" folder.  If you are using MX, the today and yesterday page in the [[MX_Administrative_Interface]] shows similar information by using the [[Cumulus_MX_Local_API#Today.2FYesterday_Data|local application programming interface]].
 
For web tags that report values that refer to a particular time of day, there is a corresponding web tag that can give the time of day, shown in same row of table below. For those that cover whole day so far, the final column contains "n/a".
 
Please note none of the time web tags can be modified by output parameters to give a date, but they can be changed from the default time format that is 'H:mm' (24 hour clock notation without leading zero for hour) for Cumulus 1 and MX. If you are using output modifiers to change how the time is reported, be careful to use ones that work for the flavour of Cumulus you are using (H and h are same for Cumulus 1, but not for MX; nn and mm are same for Cumulus 1, but not for MX).

==Monthly==
== No Commas ==


This table shows the web tags used on the '''thismonthT.htm''' web template.
Note that Cumulus does not use thousand separators, so the only places a comma can be used are as a field separator or as a decimal separator. Obviously it cannot be used for both. This section is for those locales where a comma is used instead of a full stop to separate the integer and decimal parts of a number. Some computer languages like JavaScript will not accept a comma being used for this purpose, and Cumulus uses JavaScript for various tasks, as do various third party web pages.  From '''version 1.9.3''' build 1045, Cumulus 1 (and MX) has provided some current conditions web tags, some today web tags, and some recent history web tags in an alternative format where (regardless of locale) the number is always output in a format that uses a decimal point. They all correspond to the same tag with 'RC' removed.


Because the rainfall this month does not appear on '''thismonthT.htm''' web page, it is shown in [[#Current_Conditions|indexT.htm]] table earlier in this article which is for the web page where it does appear.
===CURRENT CONDITIONS:===


The web tags in the date column output dates in the format "dd MMMM" (for once this is same for Cumulus 1 and Cumulus MX). Should you require a different output format, this can be changed using the [[#Time.2FDate_.27format.27_Parameter|format parameters]] described above. For web tags that represent daily values, there are (obviously) no corresponding time web tags, but for high and low spot values the default 'h:mm' format of the time output can be changed using output parameters. Do make sure that you get the web tag names right and the output form at parameters right.
<#RCtemp>, <#RCdew>, <#RCheatindex>, <#RChum>, <#RCinhum>, <#RCintemp>, <#RCpress>, <#RCrfall>, <#RCrrate>, <#RCwchill>, <#RCwgust>, <#RCwspeed>, <#RCwlatest>


As another example of inconsistency in how web tags added in different versions are coded, there are two web tags (highest minimum/lowest maximum temperatures) where a standard web tag is not provided by Cumulus (1 or MX) for the associated time-stamp. Consequently, for these 2 (and their corresponding tags in the this year group), there are mandatory output parameters required as shown in the table. Obviously Cumulus 1 lets you use "NN", "nn", "MM", or "mm" for the minutes, but minutes can only be represented in one way in Cumulus MX.
===TODAY:===
 
<#RCpressTH>,  <#RCpressTL>,  <#RCrrateTM>,  <#RCtempTH>, <#RCtempTL>, <#RCwgustTM>,  <#RCdewpointTH>, <#RCdewpointTL>, <#RCwchillTL>, <#RCheatindexTH>, <#RCapptempTH>, <#RCapptempTL>

Although 'Apparent Temperature' is not included as a tag, it can be [[FAQ#What_formula_does_Cumulus_use_for_Apparent_Temperature.3F | calculated]] in a script from the RC tags for 'outside temperature', 'wind speed', and 'relative humidity' values. In php language this is <tt>$RCapptempCALC =  round(<#temp> + (0.33 * (<#hum> / 100 * 6.105 * exp (17.27 * <#temp> / (237.7 + <#temp>) ))) - (0.7 * $wspeed) - 4.0, 2);</tt>.
 
There are other derivatives that can be calculated similarly from a set of simultaneous values, as described below the recent history section.
 
From '''version 3.5.4''' build 3075, all web tags (except indoor temperature <#intemp> where rc parameter not available until version 3.6.8 build 3084), that produc
=== Heading text ===
e decimal number output now support the "'''rc=y'''" option. e.g. <tt><#tempYH rc=y></tt> will report yesterday's highest temperature using a full stop to separate decimal part where the locale would normally use a comma.
 
==Yesterday==
 
Note that the Y indicating yesterday is sometimes a prefix, sometimes a suffix (with H for High, L for Low), web tags are not named consistently!
 
Many of these web tags are used on the supplied '''yesterdayT.htm''' template.
 
If you are using MX, the today and yesterday page in the [[MX_Administrative_Interface]] shows similar information by using the [[Cumulus_MX_Local_API#Today.2FYesterday_Data|local application programming interface]].


For web tags that refer to a particular time of day, there is a corresponding web tag that can give the time of day. Please note none of the time web tags can be modified by output parameters to give a date, but they can be changed from the default time format that is 'h:mm'.

This table shows most of the web tags used on the "thisyearT.htm" web template.
This table shows the web tags used on the '''thismonthT.htm''' web template.
 
Because the rainfall this month does not appear on '''thismonthT.htm''' web page, it is shown in [[#Current_Conditions|indexT.htm]] table earlier in this article which is for the web page where it does appear.


The web tags in the date column output dates in the format "dd MMMM" (for once this is same for Cumulus 1 and Cumulus MX). Should you require a different output format, this can be changed using the [[#Time.2FDate_.27format.27_Parameter|format parameters]] described above. For web tags that represent daily values, there are (obviously) no corresponding time web tags, but for high and low spot values the default 'h:mm' format of the time output can be changed using output parameters. Do make sure that you get the web tag names right and the output form at parameters right.

Do make sure that you get the web tag names right and the output form at parameters right.


As another example of inconsistency in how web tags added in different versions are coded, there are two web tags (highest minimum/lowest maximum temperatures) where a standard web tag is not provided by Cumulus (1 or MX) for the associated time-stamp. Consequently, for these 2 (and their corresponding tags in the this month group), there are mandatory output parameters required as shown in the table. Obviously Cumulus 1 lets you use "NN", "nn", "MM", or "mm" for the minutes, but minutes can only be represented in one way in Cumulus MX.

Remember that the Year-to-date runs from roll-over time on 1 January for all web tags listed here.
 
The list below does NOT include any web tags that represent seasonal derivatives, i.e. where you define the month from which they start counting. (Cumulative seasonal Chill Hours <#chillhours> and Total seasonal rainfall <#ryear> can both be found in [[Webtags#Current_Conditions|Current Conditions]]). Note, that does not imply both are included in '''indexT.htm'''.

This table shows most of the web tags used on the "thisyearT.htm" web template.
 
The web tags in the date column output dates in the format "dd MMMM" (for once this is same for Cumulus 1 and Cumulus MX). Should you require a different output format, this can be changed using the [[#Time.2FDate_.27format.27_Parameter|format parameters]] described above. For web tags that represent daily values, there are (obviously) no corresponding time web tags, but for high and low spot values the default 'h:mm' format of the time output can be changed using output parameters. Do make sure that you get the web tag names right and the output form at parameters right.


This table lists the web tags that appear in the '''recordsT.htm''' example template that is included in each release since version 1.5.1 10th January 2006.  Additional tags correctly populated from 3.6.10 (build 3086) or 3.7.0 (build 3089) are marked with a "MX" icon as they are not available in Cumulus 1. Please note the 3.6.10 release was available from 24 June 2020, if the date shown for those MX only tags is before when you installed that (or a later release), the output may show incorrect values.
As another example of inconsistency in how web tags added in different versions are coded, there are two web tags (highest minimum/lowest maximum temperatures) where a standard web tag is not provided by Cumulus (1 or MX) for the associated time-stamp. Consequently, for these 2 (and their corresponding tags in the this month group), there are mandatory output parameters required as shown in the table. Obviously Cumulus 1 lets you use "NN", "nn", "MM", or "mm" for the minutes, but minutes can only be represented in one way in Cumulus MX.


The output from the web tags shown in the date/time column have the default format that is seen on "records.htm" in the standard web pages:
Remember that the Year-to-date runs from roll-over time on 1 January for all web tags listed here.  
*The default format for an extreme month is to show the month name in full i.e. format 'MMMM' followed by the year in full.
*For an extreme day it shows the day of the month and the month name in full i.e. format "dd MMMM" (same for Cumulus 1 and Cumulus MX), prefixed with the word 'on' again ending with the year.
*For the highest/lowest within a day in the year it shows both time and date adding the word "at" before the time, and the word 'on' before the date (i.e. on the standard web page the time comes first, not as seen in admin interface).


You can change the default output on either the standard web template, or in your own file,  by using the [[#Time.2FDate_.27format.27_Parameter|formats]] features described above, but this can involve complicated use of single and double quotes and there are differences between Cumulus 1 and Cumulus MX. Please see examples section above for advice.
The list below does NOT include any web tags that represent seasonal derivatives, i.e. where you define the month from which they start counting. (Cumulative seasonal Chill Hours <#chillhours> and Total seasonal rainfall <#ryear> can both be found in [[Webtags#Current_Conditions|Current Conditions]]). Note, that does not imply both are included in '''indexT.htm'''.


Note that unlike the this month and this year web tags, the time and the date are both included in the default format of the standard time-stamp web tags for the 'highest minimum' and 'lowest maximum' temperatures, yet another inconsistency!

==All Time==
 
This table lists the web tags that appear in the '''recordsT.htm''' example template that is included in each release since version 1.5.1 10th January 2006. Additional tags correctly populated from 3.6.10 (build 3086) or 3.7.0 (build 3089) are marked with a "MX" icon as they are not available in Cumulus 1. Please note the 3.6.10 release was available from 24 June 2020, if the date shown for those MX only tags is before when you installed that (or a later release), the output may show incorrect values.
 
The output from the web tags shown in the date/time column have the default format that is seen on "records.htm" in the standard web pages:
*The default format for an extreme month is to show the month name in full i.e. format 'MMMM' followed by the year in full.
*For an extreme day it shows the day of the month and the month name in full i.e. format "dd MMMM" (same for Cumulus 1 and Cumulus MX), prefixed with the word 'on' again ending with the year.
*For the highest/lowest within a day in the year it shows both time and date adding the word "at" before the time, and the word 'on' before the date (i.e. on the standard web page the time comes first, not as seen in admin interface).


These 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.  To supply both optional input modification, and optional output modification parameters, separate them with spaces, e.g. <#ByMonthTempHT mon=7 format=hh:nn>. In that example, the highest ever temperature in July is returned in the value after processing by Cumulus.
You can change the default output on either the standard web template, or in your own file, by using the [[#Time.2FDate_.27format.27_Parameter|formats]] features described above, but this can involve complicated use of single and double quotes and there are differences between Cumulus 1 and Cumulus MX. Please see examples section above for advice.


For full details of the input modification parameters, see [[Webtags/Parameters#Input_modification_Parameters|Parameters]] page.
Note that unlike the this month and this year web tags, the time and the date are both included in the default format of the standard time-stamp web tags for the 'highest minimum' and 'lowest maximum' temperatures, yet another inconsistency!


Additional tags correctly populated from 3.6.10 (build 3086) or 3.7.0 (build 3089) are marked with a "MX" icon as they are not available in Cumulus 1. Please note the 3.6.10 release was available from 24 June 2020, if the date/time shown for those MX only tags is before when you installed that (or a later release), the feels like output may show incorrect values.

==Day/Night/Sun/Moon==
==Monthly All Time Records==
In Cumulus 1 most of these are only calculated at UTC zero hours, but are updated each hour to refer to current time-zone.
 
This table includes web tags that show the values in [[Monthlyalltime.ini]] log file, which was introduced in version 1.9.3 (build 1033, 10 Apr 2012).
 
These 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.  To supply both optional input modification, and optional output modification parameters, separate them with spaces, e.g. <#ByMonthTempHT mon=7 format=hh:nn>. In that example,  the highest ever temperature in July is returned in the value after processing by Cumulus.
 
For full details of the input modification parameters, see [[Webtags/Parameters#Input_modification_Parameters|Parameters]] page.


MX is more complicated, but most of these are calculated hourly.
Additional tags correctly populated from 3.6.10 (build 3086) or 3.7.0 (build 3089) are marked with a "MX" icon as they are not available in Cumulus 1. Please note the 3.6.10 release was available from 24 June 2020, if the date/time shown for those MX only tags is before when you installed that (or a later release), the feels like output may show incorrect values.

==Alarms==
 
[[File:badge v1.png]]There are a set of tags available in Cumulus 1 for various alarm states. In Cumulus 1, the main page will change the colour of the relevant element when an alarm condition is entered or left. You can add sounds, and enable disable each alarm parameter on the Main Cumulus screen, Edit menu.
 
[[File:Badge vMx.png]]Alarms are also available in later MX versions. In MX, the alarm conditions are shown on the bottom of the Dashboard page of the user interface. You can add sounds, and enable/disable each alarm parameter on the Alarms screen within Settings menu.
 
For both flavours, there are web tags for each alarm condition, they give a value of '1' if the alarm condition is enabled and is still currently met; otherwise '0'.

== Extreme Records ==
Possible values are 0 or 1, where 1 notes that it is currently within the hours of daylight.


There are a set of tags for the Cumulus record states. They give a value of '1' if the record has been exceeded; otherwise '0'. For daily records (e.g. temperature range), the record cannot be set until the end of the day when rollover starts. The tag is cleared in Cumulus 1 once the record has been viewed (via main screen or web tag).
|-
|<#tomorrowdaylength>
|A string giving an approximate predicted difference between the length of daylight (dawn to dusk) yesterday and length of daylight tomorrow.


=== Differences depending on Cumulus versions ===
This web tag is unreliable, basically because of the note for <#daylightlength>, and its use was not recommended. Its use is therefore not supported by Steve Loft (i.e. you use it at your own risk) in the legacy Cumulus.

|-
|<#MoonAge>

[[File:Badge v1.png]] Cumulus 1.9.x supports all the web tags listed in table below, with the exception of those relating to "humidex" and "feels like".
MX b3047 adds the 'dp' and 'rc' parameters Supports an optional 'dp' parameter, if supplied the result is returned to the specified number of decimal places. E.g <#MoonAge> gives "11" <#MoonAge dp=3> gives "11.234"


[[File:Badge v1.png]] For Cumulus 1 the tags are cleared in one of two ways:
There is some PHP script code below this table showing how this can be converted to days, hours, minutes, seconds*
#Generation of a web page where the web tag is set, clears the record for that web tag.
#Viewing of an extreme screen tab clears all records listed on that tab.


[[File:Badge vMx.png]] For versions up to 3.5.0 Cumulus MX works in a different way both in terms of how tags are set (see various topics in support forum) and how they are cleared (essentially the end of rollover clears records, so daily records are only shown for the few microseconds while rollover is being processed). From version 3.7.0, Cumulus MX offers all the web tags listed in table below, at earlier versions it offers a subset of those listed.
If the "dp" parameter is supplied, then supplying "rc=y" in addition will cause any decimal comma to be converted to a decimal point.
|-
|<#moonrise>
|Current moonrise time at the station (if moon rises on current calendar day)
|-
|<#moonset>
|Current moonset time at the station (if moon sets on current calendar day)
|-
|<#MoonPercent>
|Current percentage of moon visible (negative value indicates 'waning')


[[File:Badge vMx.png]] For MX these web tags will be set from the time of the record until a timeout value is met (by default each record remains set for 24 hours).
MX b3047 adds the 'dp' and 'rc' parameters as <#MoonAge> above
|-
|<#MoonPercentAbs>
|Current percentage of moon visible (always positive)


'''You can change the default MX timeout''':
MX b3047 adds the 'dp' and 'rc' parameters as <#MoonAge> above
*Add a <tt>RecordSetTimeoutHrs=NN</tt> entry to [[Cumulus.ini#Section:_Station|[Station] section in Cumulus.ini]]
*'''NN''' can be set to any reasonable integer representing hours (for the default set the number '''NN''' to '24').

== Extreme Records ==
|-
 
|<#LongestDryPeriodRecordSet>
There are a set of tags for the Cumulus record states. They give a value of '1' if the record has been exceeded; otherwise '0'. For daily records (e.g. temperature range), the record cannot be set until the end of the day when rollover starts. The tag is cleared in Cumulus 1 once the record has been viewed (via main screen or web tag).
|1 if the all-time longest dry period extreme has been updated, 0 if not
 
=== Differences depending on Cumulus versions ===
 
[[File:Badge v1.png]] Cumulus 1.9.x supports all the web tags listed in table below, with the exception of those relating to "humidex" and "feels like".
 
[[File:Badge v1.png]] For Cumulus 1 the tags are cleared in one of two ways:
#Generation of a web page where the web tag is set, clears the record for that web tag.
#Viewing of an extreme screen tab clears all records listed on that tab.
 
[[File:Badge vMx.png]] For versions up to 3.5.0 Cumulus MX works in a different way both in terms of how tags are set (see various topics in support forum) and how they are cleared (essentially the end of rollover clears records, so daily records are only shown for the few microseconds while rollover is being processed). From version 3.7.0, Cumulus MX offers all the web tags listed in table below, at earlier versions it offers a subset of those listed.
 
[[File:Badge vMx.png]] For MX these web tags will be set from the time of the record until a timeout value is met (by default each record remains set for 24 hours).
 
'''You can change the default MX timeout''':
*Add a <tt>RecordSetTimeoutHrs=NN</tt> entry to [[Cumulus.ini#Section:_Station|[Station] section in Cumulus.ini]]
*'''NN''' can be set to any reasonable integer representing hours (for the default set the number '''NN''' to '24').

#Although this tag is available in Cumulus 1.9.x, there is an issue somewhere in the Davis code that prevents Cumulus 1 obtaining the value (so tag always displays zero).
