Six lock triggers
- Outside every allowed slot (no matching slot today).
- The slot's minute quota is exhausted.
- Time points are exhausted (redeemed entertainment time used up).
- Periodic eye-care break (use N / rest M).
- Temporary lock issued by a parent.
- Time tampering detected (NTP offset over 300 seconds).
What's on the lock screen
- Three top buttons: unlock to Setup mode (parent password), temporary unlock to Guardian mode (password + minutes), and redeem time points.
- The top message explains the lock reason; a temporary lock also shows the remaining mm:ss.
- Top-left info bar: version, time points and traffic points balance, remote management status.
- Today's plan lists only slots matching today's day type, with the day's description (e.g. “summer vacation”) appended to the title.
- The top-right Shutdown / Restart buttons are manual and independent of the auto shutdown countdown.
Three switches and how to set them
| Switch | Default | Recommended | Notes |
|---|---|---|---|
| Pre-lock/rest reminder (min) | 5 | 5–10 | Pops up in advance so the child can save progress |
| Pre-lock countdown | On, 30s (5–300s) | 30s | Covers slot end, quota/points exhaustion, eye-care rest and temporary lock |
| Countdown can be closed | Off | Keep off | When off, the child must watch the countdown, preventing last-second grabs |
| Auto shutdown after lock (+delay) | Off | As needed | Good for families who want the PC off at curfew; independent of the manual shutdown button |
Parent remote actions
- The device card in the web console can issue a temporary lock or unlock, effective on the next heartbeat (~10s).
- Temporary lock and unlock are mutually exclusive — enabling one clears the other; if both exist, the lock wins.
- A temporary lock does not auto-clear when an allowed slot starts; it must expire or be cleared by a parent.
