Looking for selfhosted alternative to "Find my phone"

Hi, I’m looking for an alternative to Google’s Find my phone that can be self hosted. Most important feature would be to see the last known location of a mobile phone without disclosing the location to any third party system. It would be nice to have features like making the phone ring or wiping the phone remotely.

Happy to hear any ideas what you people are using.

Little known feature on Home Assistant is the ability to have any phone who has home assistant installed to be able to use it as a trigger. So you can see things like battery left and gps location. I have an automations that will ping the last location of my family members when the phone hits 2% power so I can see their last location right before the phone dies.

great idea, but a suggestion.

instead of just one ping at 2%, do three within 10 seconds of each other. this would determine direction and rate of travel.
