Yanzi moves raw and analyzed data between devices and cloud so that our partners can focus on building great products.

Yanzi handles device management including signed firmware upgrade, automatic security key management, certificate rollover, energy management, global wireless certifications and more — so that you don't have to. Talking to thousands of devices is inherently tricky, but we make it as easy as using a regular web API. We sell our own sensors using our software, but also allow partners to connect to our infrastructure.

DATA POINTS PER DAY

Cirrus API is a secure open API supporting multiple simultaneous subscribers.

Data model allow access to any data originating from any location with a uniform interface without the need to understand the sensor details.

Communication is based on JSON objects over web socket over an authenticated and encrypted SSL connection that provides broad support and understanding in the industry.

Hot path (live data) supported by Publish/Subscribe mechanism to simplify integration to 3rd party IoT frameworks.

Cold path (historical data) supported by Request/Response mechanism to enable recovery of data after loss of connectivity.

Protocol adapters available for standard message brokers such as MQTT, IBM Watson IoT Platform, IBM MessageSight, and Microsoft IoT Hub to simplify integration with IBM and Microsoft platforms.

Yanzi Cirrus Cloud supports deployment in Microsoft Azure, Google Cloud, Amazon, and IBM Bluemix. Based on Docker containers managed with Kubernetes.

Low latency, typically 250 ms both ways, allows for real-time applications.

Yanzi scales the product offering by providing sensor vendors with a fully automatic, scalable, and secure way to connect to the Cloud

Automatic Radio Channel Selection

Radio channels are automatically selected by the Gateways based on environmental parameters, such as noise levels, and regional requirements. Sensors then automatically select the Gateway with the best radio channel for that area in the building. Sensors can still roam in case a “better” paths to other Gateways appears.

Automatic Network Address

All devices on a network are required to have a unique address in order to avoid communication collisions on the network. Yanzi uses fully automatic and standardized IPv6 addressing setup while older systems typically use manually configured addresses.

Automatic Discovery

Once a device has been attached to a network, there is a process to discover other devices. UPnP is a standardized protocol to, for example, find a printer from a computer and Yanzi IoT devices use the same technique. The Gateway automatically discovers devices on the network and peers them if requested.

Automatic Over-the-Air Upgrade

New software and firmware releases are automatically pushed from the cloud out to all sensors

Automatic Introspection

Once a device has been discovered, the Gateway must figure out the capabilities and data endpoints of the device in order to know which device drivers to run and how to configure the device. This is done using a hierarchical introspection scheme that allows for new devices to be deployed without any need for new Gateway software.

Automatic Security Setup

Security must be enterprise grade to minimize attack surface and fully automated to allow fast roll-out of IoT devices. Yanzi uses authenticated links and automatic key management based on public-key cryptography, specifically elliptic curve cryptography, ECC. Devices use dual layer encryption with a unique AES encryption key per device.

All IP solution

Internet Protocol (IP) is the unifying abstraction that allow layering of diverse applications on top of diverse communication media. It allows for intermediate equipment, such as switches and access points, to forward packets without the knowledge of encryption keys or device information. Other protocols such as Zigbee, Bluetooth, and Modbus requires intermediate equipment to have full knowledge of the end-to-end application.
