Data logging time

Post by graemecrook »

Apologies in advance as I'm sure that this must have been asked before, but I couldn't find find an answer.

I'm in the process of setting up my WH1081 currently. At the moment, it is set to the default logging interval of 30 minutes (but I'll probably shorten this considerably). However, the data log file shows entries at .16 and .46 past the hour - I'm curious to know if you can change the time that it would log data, ie .00 and .30?

Thanks in advance for any help.

The station doesn't log entries at particular times past the hour, just every N minutes. You could try resetting it on the hour, but even then you're not guaranteed to get entries logged in Cumulus exactly at particular times, because the station doesn't timestamp the entries, so Cumulus has to calculate the timestamps based on the current time and the logger interval. At any given time they may be a minute or so off.

The best solution, if the timestamps matter to you, is to run Cumulus all the time, and then the station's logger is no longer an issue ;)
