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.

In short

Field device support assistant: telemetry, remote diagnosis, OTA and technician is an agent scenario in the IoT & Connected Devices sector running on the whatsapp, web, api channels. Trigger: Device fault report over WhatsApp or the support portal. The Device Support Supervisor coordinates 4 specialist agents (Dialogue Agent, Telemetry Agent, Diagnosis Agent, Dispatch Agent) across 5 systems (WhatsApp Business, Device Cloud (MQTT), Fleet Registry, OTA Service, Field Service); of 10 steps, 1 write to systems and 3 are checks or approvals. Outcome: Fault fixed remotely or technician assigned; device record and knowledge base updated. Approval rule: Bulk OTA (>100 devices) or out-of-warranty device replacement → product-owner approval.

WhatsApp: "boiler controller shows E07 since morning, no heating" + serial number photo
Device SN 8C-220914 found in the fleet registry, under warranty, firmware 2.3.1
Telemetry: 14 restarts in 6 hours, temperature sensor reads −40 °C, connectivity stable
Plan: known-issue match → remote command → OTA → verify → field visit if needed
Match: E07 + −40 °C reading = known sensor driver bug in 2.3.1 (bulletin KB-412), fixed in 2.3.4
OTA 2.3.4 pushed to the single device, installed in 3 minutes, device restarted
Verification: sensor 21.5 °C, error code clear, no restart for 15 minutes
No field visit needed; staged OTA proposal created for the 1,240 devices on the same firmware
Bulk OTA (>100 devices) submitted for product-owner approval; to start with a 5% pilot wave
To the customer: fixed, what was done in plain language; device record and knowledge base updated
