Limits

Good to know

The home-network tunnel lets Muse reach devices on your LAN that expose a local HTTP API. Treat it like giving the agent a foothold on your network.
Pairing has no manufacturer verification and can't prevent an active man-in-the-middle attack.
Builds are signed with the included development key and never enable Secure Boot. Enable NVS encryption (CONFIG_HOMEHUB_NVS_ENCRYPTION).
Custom ESP32 commands are not a documented API yet: the command set (display.draw_url, sensors.read, camera.capture, ...) is hardcoded in main/app.c.
