Staged OTA update rollout
Firmware rolls out in 1% → 10% → 100% stages; a health gate at every stage, human approval for critical fleets.
Staged OTA update rollout is an agent scenario in the IoT & Connected Devices sector running on the api, batch channels. Trigger: Signed firmware release event from CI/CD. The Rollout Supervisor coordinates 3 specialist agents (Plan Agent, Health Agent, Deploy Agent) across 4 systems (CI/CD (signed artefacts), Device Management / OTA, Observability (metrics), Slack); of 9 steps, 2 write to systems and 2 are checks or approvals. Outcome: Release reached the fleet through health gates or was rolled back automatically; every step recorded. Approval rule: Rollout to a critical fleet segment → product owner approval; automatic rollback if a health gate fails.
Staged OTA update rollout
- Release 5.0.3 signed: 46,200 target devices, 3 fleet segments
- Segments pulled: warehouse sensors, vehicle telematics, critical cold chain
- Plan: 1% canary (462 devices, low risk) → 10% → 100%; critical segment last and approved
- Stage 1 started: 462 devices, 30-minute observation window
- Stage metrics: connectivity 99.6%, crashes 0, battery drain +1.2% (threshold 5%)
- Health gate passed; difference from baseline not statistically significant
- Stage 2 started: 4,620 devices; gate passed, stage 3 ready
- Critical cold-chain segment → product owner approved the 100% rollout
- Team report: 3 stages, 0 rollbacks, 46,200 devices on 5.0.3; record stored with the release

Rollout Supervisor
Decomposes the objective, delegates to agents, manages approval points, merges the result.

Field device support assistant: telemetry, remote diagnosis, OTA and technician
The customer says "the device is dead"; telemetry read, remote diagnosis made, update pushed, technician dispatched with the right part if needed.
Device fleet anomaly triage
Telemetry anomalies from thousands of devices are clustered, root-cause candidates listed, one incident reaches the right team.
Cold-chain excursion response
A temperature excursion is assessed instantly, product risk computed, a field crew dispatched, the quality decision recorded.
Time to move from experimenting with AI to transforming with it.
