You specify which value you want from the array by using parameters on the web tags for number of days ago, hours ago, and minutes ago. The same d, h, and m, parameters are used by Cumulus 1 and MX. | You specify which value you want from the array by using parameters on the web tags for number of days ago, hours ago, and minutes ago. The same d, h, and m, parameters are used by Cumulus 1 and MX. | ||
All values supplied for parameters must be whole numbers. | |||
If you don't supply any parameters, the result is undefined for Cumulus 1, and an illegal web tag for MX. | |||
<#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>). | |||
<#RecentOutsideTemp d=1> will give the temperature one day ago. '''Please note:''' Some Cumulus users say that using <#RecentOutsideTemp d=1 m=1> is more reliable at getting the temperature at a similar time the day before, the extra minute apparently gives better results when you might not be using Cumulus all the time, or your weather station might have some drift on when it supplies readings. See which works best for you. | |||
<#RecentOutsideTemp d=1 h=1 m=1> will give the temperature one day, one hour and one minute ago. | |||

Please note that parameters specify time-stamped array element to retrieve based on counting back from current local time''' so the result for ''any period including when clocks change'' may not be quite what you anticipated. | |||
