FAQs
Answers to the most frequently asked questions about the Optra platform.
General
What is Optra?
Optra is Lexmark's IoT and data platform. It provides tools to connect and manage IoT device fleets, stream and analyse telemetry data, and accelerate time-to-value through pre-built solutions in the Accelerator Hub.
What is the difference between Optra IoT and Optra Data Accelerator (ODA)?
Optra IoT focuses on device connectivity, management, and real-time telemetry. ODA is a metadata-driven data management layer that ingests, transforms, and routes data through a LakeHouse architecture. They are complementary and often deployed together.
Is Optra available as a cloud service or on-premises?
Optra is cloud-native and hosted on Microsoft Azure. A disconnected (air-gapped) deployment option is available for environments with strict network policies — see the platform documentation for details.
Devices & Connectivity
How do I register a device?
Devices are registered through the Optra platform under Devices → Register, via the REST API, or using the Azure Device Provisioning Service (DPS) during manufacturing. See the Enroll a Device guide for step-by-step instructions.
What protocols do devices use to connect?
Devices communicate over MQTT or AMQP via Azure IoT Hub. Devices with limited connectivity can batch and send data over HTTPS.
How many devices can I connect?
There is no hard ceiling — the platform auto-scales. Limits are governed by your subscription tier. Contact your Lexmark account team for enterprise fleet sizing.
Data & Security
How long is telemetry data retained?
Raw telemetry is retained for 90 days by default. Aggregated data pipelines through ODA can persist data in your own LakeHouse indefinitely.
Is data encrypted in transit and at rest?
Yes. All data is encrypted in transit using TLS 1.2+ and at rest using AES-256 via Azure Storage encryption.
Can I export my data?
Yes — see the Export Device Telemetry guide for bulk export options, and the API reference for programmatic access.
APIs & Integrations
Where can I find my API key?
Navigate to Settings → API Keys in the Optra platform. See the Generate an API Key guide for detailed instructions.
Are there rate limits on the API?
Yes. Standard accounts are limited to 120 requests per minute. See the Rate Limits page for full details and guidance on handling 429 responses.
