RaZberry turns the Raspberry Pi into an affordable smart home gateway:
There are few electronic boards that have gained as much attention and excitement as the Raspberry Pi. The little 35 US$ microcomputer is a quite powerful computing engine with very capable graphics engine and other multimedia IOs. Initially intended as a toy for newcomers to get into the PC development world, the Raspberry Pi has hit seven digit sales figure in short time and has become more and more a commercial platform further lowering the entry barrier for new embedded computing solutions.
The next step in this evolution is called RaZberry. This enhancement kit for the Raspberry Pi turns the microcomputer into a fully featured controller for Z-Wave wireless smart home networks. Z-Wave is the communications technology used by the world’s largest ecosystem of interoperable devices for smart homes. This ecosystem has more than 750 interoperable devices from numerous different vendors across the world these products are listed at products.z-wavealliance.org,.
RaZberry is a pan-European project, the company behind it - Z-Wave.Me is located in Geneva/Switzerland. The software was mainly developed in Moscow/Russia and the hardware is Made in Germany.
The RaZberry solution comes in three parts. First, there is a little daughter board with the Z-Wave transceiver that plugs in the GPIO pin header of the Raspberry Pi board and not blocking the USB ports that may be used for other useful things like 3G uplink or WIFI sticks.
Second, the daughter board holds the Sigma Designs Z-Wave transceiver with the licensed Z-Wave firmware managing the Z-Wave networking protocol.
The third and most interesting part is Z-Wave middle-ware called Z-Way and is provided by Z-Wave.Me. –Z-Way comes installed on the Raspberry Pis SD card.. i. A single line of commands is all that is required to start Z-Way and start developing Z-Wave control applications. Z-Way implements all needed functions of a Z-Wave smart home gateway. It allows managing the network by including and excluding devices, ontrols actuators, reads sensors and connects all the dots together using direct associations between Z-Wave devices and/or executing scripts.
The idea behind Z-Way is to give people the chance to do their own gateway design and function. Hence, Z-Way comes with a simple to use JSON Web interface that can be used by HTML and JavaScript or Mobile phone apps. Several example Graphical User Interfaces (GUIs) of varying complexity level are provided to teach people how to use this interface
A complete Demo User Interface (UI) is included that provides complete control of a Z-Wave network. This demo is fully functional but not necessarily fashionable. The idea is to encourage people in the first step to beautify this interface but also to add more functions. No high-level software skills are needed for this except a basic knowledge of HTML and JavaScript.
The key in smart home technology is the handling of the interrelationships of different devices with each other. Most systems provide for the manually prompted switching of devices and reading of sensors but for a truly smart home the application must add automation. That is, it must automatically control actuators depending on time of the day, external circumstances such as weather and information acquired from other Z-Wave devices. This type of operation is defined by writing scripts. Most smart home gateways either limit the choices available to define these scripts or require special programming skills for scripting. Z-Way offers to define for detailed scripting in JavaScript as well the same language that is used for the GUI. The commands in the GUI and the commands in the Scripting back end are similar significantly simplifying the use of scripts.
Users can write their GUI in HTML and JavaScript and test most
commands in their web browser before uploading the code to the Z-Way server for automated execution. This command line operation greatly simplifies product creation.
The complete system, daughter card with Z-Wave transceiver, Z-Wave firmware and Z-Way middle-ware sells at a recommended price point of 49 EU resp. 59 US$. Commercial projects with larger volume can expect discounts. All you need to add is a Raspberry PI and your creativity.
The RaZberry is now available online e.g. at www.zwaveproducts.com. Further support and information including documentation, users forum and a news blog can be found at razberry.z-wave.me.
