By popular request I've started pushing a few of my applications to GitHub, we'll see how that goes - since their bandwidth limits are rather restrictive. All the old/previous versions of the code will remain hosted on this website. You can find the code at this location.
Changes in the latest version:
-Added statistics for number of GPS sats and battery level
-Added replay functionality
-Optimized bandwidth usage
-Finished support for LL01, JIMI's 4g asset tracker, including battery level
-Misc frontend improvements
