IoT Device Lifecycle
Every state an IoT device goes through, from manufacture to decommissioning, including updates, faults and replacement.
Drawing diagram…
What this diagram shows
- Devices are registered at manufacture and claimed by customers
- Firmware updates are a state with rollback on failure
- Decommissioned devices have their certificates revoked
Prompt used
State machine for an IoT device: Manufactured, Registered with identity, Shipped, Claimed by the customer, Provisioned, Active. From Active it can go to Updating (firmware) then back to Active or Rollback on failure, to Offline when it stops reporting, to Faulty and then Replaced, or to Decommissioned with its certificate revoked.
