Read and send Telegram messages directly from a Flipper Zero's screen.
A self-hosted FastAPI server on a Raspberry Pi talks to a custom FAP application over an
ESP32 Wi-Fi bridge, with Cyrillic transliteration, paginated chats, and an on-device keyboard.
Every message the bot sees is stored in the server's database.
Traffic between the server and the Flipper is encrypted with a shared secret,
and a web UI allows browsing and deleting stored messages from a browser.
