A device with missing telemetry
An unknown state should be visible.
A device reports status at an expected interval. When no recent update is available, the view changes to “Telemetry overdue” and creates an assigned investigation item.
A reviewer records what was checked and whether communication was restored. The concept is about operational visibility, not certified fire-alarm functions or a safety-critical control system.
What remains project-specific: source interface, device meanings, reporting intervals, site procedures, maintenance responsibilities and specialist validation.

- Control
- The expected reading is overdue. Device condition is unknown. Acknowledging the event must not label the device healthy.

Evidence and event history
Original evidence: Example timeline: last reading 09:00; overdue at 09:10
- 09:00 — Example record received
Follow the example timeline from the first observation to the recorded outcome.
An actual monitoring scope defines signal meaning, refresh expectations, fallback procedures, maintenance ownership and qualified control boundaries.
