Open Source IoT Software

Johnny-Five is the JavaScript Robotics & IoT Platform. Released by Bocoup in 2012, Johnny-Five is maintained by a community of passionate software developers and hardware engineers. Over 75 developers have made contributions towards building a robust, extensible and composable ecosystem. The only kit designed for getting started with Johnny-Five! The Johnny-Five Inventor's Kit, from Bocoup and SparkFun, is now available! It's designed for anyone who wants to get started with JavaScript-powered robotics. The J5IK includes a Tessel 2, and everything else you need to do 14 experiments! No programming or soldering experience is required. Microcontrollers and SoC platforms like to say "Hello World" with a simple blinking LED; the following demonstrates how to do this with the Johnny-Five framework.

Gobot makes controlling robots and devices incredibly simple and fun. This program connects to an Arduino, and toggles an LED, every one second. Support for devices that use Analog Input/Output (AIO) communication have a shared set of drivers provided using the "gobot/drivers/aio" package. Support for devices that use General Purpose Input/Output (GPIO) communication have a shared set of drivers provided using the "gobot/drivers/gpio" package. Gobot has a extensible system for connecting to hardware devices. Gobot includes a RESTful API to query the status of any connection, device or robot running in your swarm. It additionally has the ability to issue commands directly to your devices and robots. It also comes with the robeaux React.JS interface baked right into its API server for quick and easy configuration.

The Device Defender library enables you to send device metrics to the AWS IoT Device Defender Service. This library also supports custom metrics, a feature that helps you monitor operational health metrics that are unique to your fleet or use case. For example, you can define a new metric to monitor the memory usage or CPU usage on your devices. This library has no dependencies on any additional libraries other than the standard C library, and therefore, can be used with any MQTT client library. This library is distributed under the MIT Open Source License. This library has gone through code quality checks including verification that no function has a GNU Complexity score over 8, and checks against deviations from mandatory rules in the MISRA coding standard. Deviations from the MISRA C:2012 guidelines are documented under MISRA Deviations. This library has also undergone static code analysis using Coverity static analysis.

The AWS IoT Device Shadow library enables you to store and retrieve the current state (the “shadow”) of every registered device. The device’s shadow is a persistent, virtual representation of your device that you can interact with from AWS IoT Core even if the device is offline. The device state is captured as its “shadow” within a JSON document. The device can send commands over MQTT to get, update and delete its latest state as well as receive notifications over MQTT about changes in its state. Each device’s shadow is uniquely identified by the name of the corresponding “thing”, a representation of a specific device or logical entity on the AWS Cloud. See Managing Devices with AWS IoT for more information on IoT "thing". More details about AWS IoT Device Shadow can be found in AWS IoT documentation. This library is distributed under the MIT Open Source License.

SiteWhere is an industrial-strength, open-source IoT Application Enablement Platform that facilitates the ingestion, storage, processing, and integration of IoT device data at a massive scale. The platform leverages a microservices architecture that runs on top of cutting-edge technologies such as Kubernetes, Istio, and Kafka in order to scale efficiently to the loads expected in large IoT projects. SiteWhere embraces a distributed architecture that runs on Kubernetes and provides both infrastructures such as highly-available databases and MQTT brokers as well as microservices to facilitate various aspects of IoT project development. The platform is built with a framework approach using clearly defined APIs so that new technologies may easily be integrated as the IoT ecosystem evolves. SiteWhere is composed of Java-based microservices which are built as Docker images and deployed to Kubernetes for orchestration.
