Hello. I just got a google pixel with grapheneos, and would like a way to use Apple's find-my or something similar with family members who still use Apple. I would like something open source that can either proxy my location to Find My or serve as an alternative. I know these apps and services are inherently not private but I do need it so please don't be the guy to say "just don't use it," I would if it were an option. Thanks.
Out of curiosity, how are you connecting your phone to home when you're out? Are you exposing HA, vpn? What sensors do you have enabled in the companion app? Do you have high accuracy enabled? How's your battery drain?
I use Nginx ProxyPass to expose HA. I know people who use the VPN feature of their internet routers.
But I myself just have a few sensors activated in the companion app.
