→Cumulus takes a long time to download the data from my Davis station at start up
| Line 389: | Line 389: | ||
When Cumulus starts, it asks the station for all the data from the logger since the last time it was running. If the timestamp that it supplies does not exactly match the timestamp of an entry in the Davis logger, the station has a strange 'feature' where it decides to send the entire contents of the logger. This will take some time to download, during which the Davis console display may appear to freeze. | When Cumulus starts, it asks the station for all the data from the logger since the last time it was running.

It is recommended that you set the logging interval in Cumulus to the same interval as the station, then Cumulus will be able to make sure it uses a timestamp that matches an entry in the logger. Note that this is mentioned in the readme.txt file which appears during the Cumulus installation, which you were asked to read at the time. If you didn't read it, it is strongly recommended that you do so now; it contains important information. | It is recommended that you set the logging interval in Cumulus to the same interval as the station (using Weatherlink), then Cumulus will be able to make sure it uses a timestamp that matches an entry in the logger.
