Monitoring that stays
outside the blast radius.
Equate keeps customer-network access on site. The cloud receives validated, durable telemetry and presents monitoring state without gaining a management path into the customer plane.

Understand centrally.
Observe first. Deliver safely.
MQTT is a delivery boundary, not the system of record. The collector continues polling when cloud transport is unavailable.
Enqueue before publish
The collector removes buffered telemetry only after broker acknowledgement.
Commit before acknowledge
Database failure leaves a message unacknowledged so QoS 1 delivery can retry safely.
Present persisted evidence
The dashboard reads API projections; it does not query devices, collectors, or the database directly.
Make impact visible without guessing.
Health is evaluated where the collector can observe polling results and configured dependencies. The dashboard preserves that evidence rather than recomputing it.
Healthy
The device responded and its temperature is below the active threshold.
Warning
The device responded, but temperature is at or above its collector policy threshold.
Critical
The device is directly unreachable after the configured consecutive-failure threshold.
Unknown impact
All configured upstream paths are unavailable. This is dependency evidence, not a claim that the device itself has failed.
Plan the monitoring path.
Review collector placement, inventory, outbound connectivity, and dashboard requirements before rollout.
