About OSE

Open Smart Environment software is a suite for creating multi-instance applications that work as a single whole. Imagine, for example, a personal mesh running on various devices including HTPCs, phones, tablets, workstations, servers, Raspberry Pis, home automation gadgets, wearables, drones, etc.

OSE software consists of several npm packages: a framework running on Node.js, an HTML5 frontend, extending packages and a set of example applications.

Set-up of current example applications. Here, OSE provides a Media player running on an HTPC that can be controlled by an IR remote through LIRC and is capable of playing streams from a DVB streamer and control devices through GPIO pins on a Raspberry Pi

For more information about OSE see the documentation.

Status

• Pre-alpha stage (insecure and buggy)
• Unstable API
• Patchy documentation
• Low test coverage (1 %)

This is not yet a piece of download-and-use software. It is important to understand the basic principles covered by the documentation.

However, this software is successfully and continuously used since end of 2013 in one installation running 7 OSE instances spread over several Raspberries, HTPC and notebook.

Platforms

OSE has the following prerequisites:

• Node.js (>0.12) running on Debian Jessie and Raspbian
• Recent version of Firefox or Chrome browser

Usage

For the Media player application to work, you need the following prerequisites:

• Node.js > 0.12, npm, git
• PulseAudio configured with the D-Bus control interface pactl load-module module-dbus-protocol
• VLC 2.2 or newer sudo apt-get install vlc

To install the example application, do the following:

sudo apt-get install libdbus-1-dev pkg-config
git clone https://github.com/OpenSmartEnvironment/ose-example-player
