When Cumulus is running normally, entries are stored once a minute, regardless of how often Cumulus interrogates the weather station (might be every 10 seconds, or more or less frequently) and regardless of how often the weather station gets updated readings from sensors (might be every few seconds, every 40 seconds, every minute or less frequently). This can mean that the readings stored on a 1-minute basis may actually be duplicates if the station has not supplied a new value since the previous minute, or may not capture every reading from sensors if they are read more than once in a minute. | When Cumulus is running normally, entries are stored once a minute, regardless of how often Cumulus interrogates the weather station (might be every 10 seconds, or more or less frequently) and regardless of how often the weather station gets updated readings from sensors (might be every few seconds, every 40 seconds, every minute or less frequently).

When Cumulus is restarted, if the weather station provides historical catch-up data, then the interval between entries for that period when Cumulus was not running, is stored at whatever interval the historical catch-up data uses. | When Cumulus is restarted, if the weather station provides historical catch-up data, then the interval between entries for that period when Cumulus was not running, is stored at whatever interval the historical catch-up data uses. Entries less than a week old, from when MX was previously running will be retained, and those will be at one minute interval. | ||
