No you won't lose a thing if you follow the upgrade instructions. But beware that the .deb package does not work on the old raspbian wheezy release, it requires the new raspbian jessie release. Unfortunately there is no official way to upgrade raspbian from wheezy to jessie (assuming you have the old wheezy release since jessie was released sometime last autumn). You can still do a manual install on wheezy if you install the missing dependency (argcomplete) with pip. A safe way to try the new version with no risk is to install on a new sd-card and then move over the database and config file, see: https://github.com/motoz/PellMon/wiki/B ... ve-PellMon
Ok, thanks for the tip, i defenetly have the old wheezy version.. I hope to have some time to upgrade this week, thanks for all your great work, its so nice to have stats, and history about how the pellet burner runs
