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...

Make your Raspberry Pi to a Wi-Fi controllable LED Light using LED stripes with WS 2811 controller. This software enables the raspberry to provide a web server interface (HTTP / Rest) for controlling the connected LED stripe. That project bases on the WiringPi lib, Indy for Lazarus and also on the Tinkerforge bindungs for Lazarus. The Stripe must be connected with the Tinkerforge Masterbrick and the LED-Stripe bricklet. WiringPi is used to control the GPIOs for some feature and Indy (Internet...

bluetroller is a library and interface for controlling all kinds of bluetooth LE devices. A vast number of devices can be controlled via Bluetooth LE, including fitness trackers, lighting, camera sliders, gimbals and many more. Right now these devices can only be controlled via phone apps which are frequently buggy, unmaintained and will stop working after some future phone update. This project aims to grow to become an exhaustive library of these devices.

Some outdoors weather sensors transmit useful info on 433 MHz . This project forwards such info over a computer network (WiFi) to a MQTT broker. Any applications can pick up the info from there.

This is a Sketch for the arduino IDE to enable the usage of a DHT22 sensor connected to a NodeMCU (ESP8266) with MQTT. Also supported are 2 status LED's and a SPI diaplay. After start the sensor device, there will be a Wifi-AP for configuration purposes. After successfully configuration, the sensor is connected as a Wifi-client and send the temperature and humidity data via MQTT within the given intervall. During AP-mode and client-mode, there are some RESTful functions (HTTP-requests...
