RaZberry

Thank you for purchasing the RaZberry, which transforms your Raspberry Pi into a Z-Wave enabled Home Gateway. It implements the Z-Wave transceiver, including the low-level network protocol, the Z-Wave application level protocol, and a JavaScript-based automation engine.

Installation Steps

Here are the four steps to install the system:

1. Plug the RaZberry onto your Raspberry Pi as shown in the figure.
2. Power up your Raspberry Pi and log into the OS.
3. Execute the following command line:

   wget -q -O - http://razberry.z-wave.me/install | sudo bash

4. Go to http://IP_OF_RASPBERRY:8083 to access the demo UI.

Demo User Interface

The Demo UI exposes all functions of the RaZberry software, allowing you to control your Z-Wave network from this single interface. It is designed to be user-friendly, enabling you to create your own Home gateway application and user interface based on RaZberry. Basic knowledge of HTML, CSS, and JavaScript is sufficient. The website razberry.z-wave.me provides full documentation for the Demo UI and the JSON Application Programmers Interface (API), along with demo code for better understanding. You can also find information about the RaZberry concept, access the discussion board for community support, and get the latest updates from the RaZberry community.

Technical Data

Firmware Enhancements

The firmware on the Sigma Designs Z-Wave transceiver chip is based on the original design recommendations from Sigma Designs. Compared to the standard firmware used by most Z-Wave USB Sticks and other Z-Wave Host Interface hardware, the RaZberry firmware offers several extensions and enhancements:

• Backup and recovery function including network topology.
• Extended Node Information Frame (up to 20 Command Classes possible).
• Optimized transmitting queue handling to speed up the transmitting process.
• Firmware update from the Raspberry Pi OS level in the field.
• Extended Wakeup Notification Handling to extend battery life for battery-operated devices in the network.

Z-Way Protocol Stack Features

The Transceiver Firmware communicates with the Z-Way communication stack using the serial interface /dev/ttyAMA0. The Z-Way communication protocol stack organizes and manages the Z-Wave network and its devices, offering a simple-to-use and easy-to-understand user interface that hides most of the complexity of the Z-Wave wireless network. The Z-Way protocol stack offers many unique features:

• Certified Z-Wave Middleware (Z-Wave Alliance Certification Number ZC08-11040003).
• Full Z-Wave based Smart Home Gateway (Network management [Include, Exclude, Reorganize], Device interview and configuration, Management of direct associations between devices, Sensor access and polling, Operating actors and access actors status, Automation engine with rules, scripts, and timers using JavaScript, Job queue management).
• Local scripting based on Google JavaScript Engine V8.
• Optimized data subscription model to minimize data traffic over the net.
• Localization based on XML language files.
• Utilizes the Pepper One Z-Wave device database for user-friendly configuration and association handling.

Compliance and Warranty

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: (1) Reorient or relocate the receiving antenna. (2) Increase the separation between the equipment and receiver. (3) Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. (4) Consult the dealer or an experienced radio/TV technician for help. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the device. Where shielded interface cables have been provided with the product or specified additional components or accessories elsewhere defined to be used with the installation of the product, they must be used in order to ensure compliance with FCC regulations.
