eaZy is a Home Automation project that proposes easyness on installation and configuration by using ZWave devices and a simple Web interface.

Note: eaZy is an early stage project.

Features

Control of ZWave devices by using a simple web interface.

What you will need

• ZWave Devices: The system communicates with ZWave devices by using a ZWave USB Controller (such as the ZStick 2).
• Host: Any hardware supporting a debian-like linux distribution may work, though only a Desktop and Raspberry Pi have been tested until now. It is recommended Ubuntu or Raspbian, which used during development.
• Software: Currently, there is no automatic installer. Though, the installation is not a big issue: just follow the scripts/install_dependencies.sh file.
• Connection: The host needs to be connected to the local network so it can be accessed. Example: http://raspberrpi.local:3000 or http://<host-ip>:3000.

Contribute

If you are willing to contribute, take a look at the TODO list above. There is a lot of documentation (though it is written in portuguese). Current system architecture and TechStack:

• Home Stack: component that implements the Home Automation logics and data persistency. Implemented in Lua.
• eaZy Web: currently the only User Interface component, implemented using Node.js (back-end) and AngularJS (front-end).
• Device Controller: interface between the system and the ZWave devices network. Implemented in Python, using the Python OpenZWave as API to communicate with the devices.

To view each component structure, take a look at the docs/images/ folder.

TODO

Here is a list of features/improvements that could yet be implemented:

• Tests: yes! there are no tests yet. Not proud of it, I really know the importance about testing, but since the requirements changed constantly during development and the deadline was short, the tests would have needed to be rewritten and updated too frequently to pay for it self on time.
• User Access Control: there still is no authentication or security measures to operate eaZy. A first approach would be to implement a user-authentication REST API to the eaZyWeb component,so every user request has to be authenticated before taking effect.
• Statisctitcs: the system could store logs (about user activity and ZWave devices activity aswell) so statistics like Device Consumption, Overall Energy Cost, User Traking (using presence sensors), Behaviour Analysis, and so on, could be generated.
• Design Improvements: the User Interface design could use a lot of improvements.
• New UI Component: a new User Interface like client-side application on Android, iOS or Windows.
