FindMySync is a simple Mac app, which synchronizes Apple Find My data (devices, items, … location & battery info) into a custom HTTP endpoint. You could use it to sync your devices location with Home Assistant device tracker.


FindMySync is opensource, you can find the full sourcecode at https://github.com/MartinPham/FindMySync

Open the FindMySync.app.dmg, there will be FindMySync.app inside, you can copy it into Applications folder.
