Thanks, I’ve been looking for something like this since forever. OwnTracks is the thing I previously heard about, but at the time it required you to set up your own mqtt server for data ingestion. I’d rather not have to maintain something like that.
I use OwnTracks. You don't need an MQTT broker (anymore?), though that is one of the options. A HTTP server works just fine, and there's an app (ot-recorder) that will handle saving your location history to disk.
