Hi, By 'dongle' I presume you mean one of the Davis data loggers. If so the logger has a fixed memory and stores archive records in a round robin fashion (ie once memory is full the oldest record is overwritten with the newest). How long a history you can store depends on your archive interval; the logger can store 2560 records so at one minute that is a little over 42 hours, at five minutes just under nine days and at 120 minutes about seven months. The default 30 minute archive period gives about two months of recorded history. Sounds like you may have a 60 minute archive period?
And yes on startup WeeWX will download any (previously unseen) history from a Davis station.
