Any self-hosted option for real time location sharing?

Hi there, everyone. For various reasons, our family makes use of Life360. I'm wanting to move to either a linux or completely degoogled phone…

I use Home Assistant for this. It works very well and the data is all local. It’s probably a bit heavy if you don’t use the other parts of home assistant though.
After several projects this is the best solution by my lights. The home assistant companion app coupled with tasker is pretty powerful. You can call remote location updates via intents and use taskerHA plugin for back and forth communication between the two.
