Live View
Stream of keystrokes as they arrive in the web UI
The Live panel of the Web UI shows every keystroke from the plugged USB keyboard the moment it arrives.
What you see
- Calibrated text — what was actually typed (e.g.
password123). - Raw scancodes — the USB HID codes (e.g.
0x1A 0x04 0x16 0x16 ...) for low-level debugging. - Timestamps — milliseconds since session start.
- Pairing state — current BLE host (paired, connected, or none).
- Match indicators — when a keyword or regex rule fires, the matched substring highlights.
Use cases
- Verify calibration — type a known string, confirm it appears correctly.
- Audit keystrokes against expected input — observe what an authorized user types.
- Tune detection rules — watch live to refine keyword lists and regex patterns before locking them in.
Export
Click Export in the Live panel header to dump the current session to JSON or CSV. Exports save to the on-device filesystem and can be downloaded via the File Manager.
The Live view never persists keystrokes to disk by default — only explicit exports are saved. Sessions are kept in RAM and clear on power-off.
