Question: Is there any way to download the data from the monitor to my computer without removing the memory card? Is there a hack for That?
how are you at writing python code?
the windows software provided by ambient weather includes the option 'SD Card File' that pulls data from the devices and saves it as a csv file.
it should be fairly straightforward to add that capability to the weewx-hp3000 driver (as of july 2017, the weewx-hp3000 driver only reads current data). then you could get the historical data on any platform, not just windows. and you could script it with something like:
Code: [Select]
wee_device /etc/weewx/hp3000.conf --download --format csv > filename.csvthe usb protocol was pretty easy to decode and reverse engineer - it is documented in the weewx-hp3000 comments.
all you would have to do is sniff a couple of 'Menu -> SD Card File' operations, isolate the command, and decode the returned data. the wee_device infrastructure provides the context in which to run it.
i'd love to help, but i'm swamped right now
