Developer Leon Böttger has created a custom firmware that allows any Espressif ESP32 microcontroller to act as a Google Find My Device tag. The project is still experimental and lacks certain features like Fast Pair and MAC rotation but provides standalone tools for tracking. The firmware is available under the GNU General Public License 3 on GitHub.
The FindMyFlipper app allows a FlipperZero device to emulate Apple AirTag, Samsung SmartTag, or Tile Tracker, extending its tracking capabilities. Users can clone existing tags, customize beacon intervals, and optimize for battery life. The app also generates OpenHaystack key pairs for Apple's FindMy network. Detailed instructions for installation and usage are provided.
