Device Manager and Data Storage

As developers and IoT product designers, we can't neglect the effort needed to deploy, manage and protect our devices for the entire duration of their life cycles.

For this often daunting task, Zerynth developed the Zerynth Device Manager. It is a device management service that speeds up the development of scalable, secure and reliable IoT solutions.

Features

  • Provisioning: associate device certificates securely stored in a top-notch crypto element with your Zerynth Device Manager account in just a click. No more cumbersome and insecure credentials generation that hinders security and slows down mass deployments.
  • Connectivity: transfer data to the Zerynth Device Manager with state of the art two-way authenticated and encrypted TLS connections.
  • Life Cycle Management: perform complex orchestration tasks by sending jobs and over-the-air updates to your fleets; from an easy to use GUI or programmatically via CLI or REST APIs.
  • Data Availability: avoid losing precious data by temporarily queueing them on the Zerynth Device Manager when your data sinks are down.
  • Integrations: forward data via convenient webhooks or API to your final IoT application or even better to the Zerynth Storage and Zerynth Dashboard services

Zerynth Device Manager can be adapted to all kinds of deployments, being available as a SaaS hosted by Zerynth or as an on-premises containerized application.

Zerynth Device Manager is based on the following key concepts:

  • A Device is the cloud representation of the physical IoT device. A Zerynth Device Manager device is associated to a physical device during provisioning. An action performed over a Zerynth Device Manager device (i.e. sending an update or a new configuration) is always reflected and communicated to the physical device.
  • A Workspace is an entity that groups together all the devices belonging to a single project. Zerynth Device Manager accounts can have multiple independent workspaces, one for each project.
  • A Fleet is a group of devices belonging to a Workspace. You can use fleets to group devices with similar features and applications. Fleets allow sending bulk device commands, OTA updates and jobs.
  • An Integration is an interface between the Zerynth Device Manager and other internal or external services like the Zerynth Storage or your IoT application backend. Integrations are used to forward data and events out of the Zerynth Device Manager.

Devices send data, events and receive requests from the Zerynth Device Manager. In particular:

  • A Tag is a data label used for querying data. Each device can publish its data under multiple Tags and the Zerynth Device Manager will take care of dispatching them to integrations accordingly.
  • A Condition is an event on steroids. Conditions can be opened, updated and closed by devices to notify specific status change (e.i. Battery status). Conditions can be monitored in real-time using the Zerynth Device Manager web interface or via API.
  • A Job is a command sent to a device. Jobs map to firmware functions like reset, diagnostics, control, update firmware, etc...

Zerynth Device Manager can be easily accessed via at https://zdm.zerynth.com or, for more advanced usages, via command Line or APIs.

The On Premise way

If you don't want to be locked in by a third party cloud or you already have a containerized application, the easiest way to integrate with the Zerynth Device Manager is exposing an endpoint for data ingestion.

Just create a webhook integration from the Zerynth Device Manager web app and point it to the http address of your endpoint. The integration will keep sending data to your endpoint where a service running on your servers will receive them and be responsible for database insertion.

It seems a lot of work but we have you covered: from here you can checkout a demo repository with all the components already in place!

Storage

Zerynth Storage is a dedicated cloud service optimized for storing time series data coming from IoT devices. It offers APIs to retrieve the raw or aggregated data and to export it into other formats (csv, json).

Features

  • A dedicated GUI for monitoring, filtering and controlling the data flowing to the workspace
  • Automatic recognition of incoming data.
  • Advanced REST API to get both raw and aggregated data (e.g., average value of a column)
  • Single or periodic export of data of single or fleet or multiple fleets of devices in CSV or JSON formats.
