Now with IEC61850 support! This project combines existing open source projects and tools to create a very capable, mobile and cloud-friendly HMI system that can rival proprietary software. This approach makes it possible to join forces of each project (Chromium, SVG/HTML5, PHP, Lua, SQLite, Inkscape, Lib61850, OpenDNP3, Nginx, Vega, PostgreSQL, Grafana,…) to achieve a great set of open, evergreen, modular and customizable tools for building great HMIs for automation projects. This is not...

The Device SDK simplifies access to the Pub/Sub functionality of the AWS IoT broker via MQTT and provides APIs to interact with Thing Shadows. The SDK has been tested to work with the AWS IoT platform to ensure the best interoperability of a device with the AWS IoT platform. The Device SDK provides functionality to create and maintain a MQTT Connection. It expects to be provided with a Network Connection class that connects and authenticates to AWS IoT using either direct TLS or WebSocket...
