OpenDomoOS is a project that implements an accessible and secure home automation system, entirely based on OpenSource. The license under which the project is being developed the General Public License (GPL). This license guarantees freedom in the use of software, a core value of the current technological society. In general terms, this means that OpenDomo can be used, copied, modified and distributed freely.
The main website of this project is here, but in this page you can find useful information about it.
At the moment, several sub-projects are already hosted in Github.
If you don't want to go through the documents, and you just want to see things working, you should download from here the last version of OpenDomoOS. In the same page you will find the instructions to install it in a Virtual Machine or on your Raspberry PI.
If you are a brave developer, you can also checkout this repository and start executing the following command on the root:
$ ./sdk.sh help
Further instructions will be given to you then ;)
