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. | 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.

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, and optional output 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. | 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.

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. | 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.
