Or even better yet just forget about the memory database and write the
database directly to a mounted drive. It's far safer. Maybe it's still not
foolproof if you're having power issues, but it is much more robust.
Reconfigure /etc/fstab to mount the stick or HDD somewhere permanent.
Edit the DatabaseTypes section in /etc/weewx.conf to point to that new
drive.
[DatabaseTypes]
ยทยทยทยท
# Defaults for SQLite databases
[[SQLite]]
driver = weedb.sqlite
# Directory in which the database files are located
SQLITE_ROOT = /mnt/my_usb_mounted_drive/weewx
And then continue backing up that database! (of course!)
I'd hasten the RTC addition, and when you do set that up make sure that it
actually works when the network is disconnected. Correct time is an
essential for weewx, it's the primary key in the database for starters.
If you have any questions on implementing any of the above, then I'll see
you back over at rorpi discusion :-)
