Self-hosting your location history with OwnTracks

The feature I like most about the Google Timeline is the automatic transportation mode detection. It just knows how many kilometres I cycled any day etc. and also aggregates these into a monthly email. And it works completely automatic without fiddling around with anything.
No selfhosted alternative can do this afaik..
Hosting your own services. Preferably at home and on low-power or shared hardware.
