RaZberry 2 Card - Z-Wave Plus GPIO Adapter for RaspberryPi from Z-Wave.ME

RaZberry 2 is a card manufactured by ZWAVE.ME that is inserted into the GPIO bus of the Raspberry PI. Turn a Raspberry PI into a gateway or home automation control unit for home automation with Z-Wave Plus technology. The included Z-Way software, downloadable and installable in the Raspberry PI, allows the Raspberry PI operating system to communicate with the RaZberry card and offers a Web configuration interface accessible from the browser of our PC or simple smartphone to the powerful time It also offers a JSON Web API that we can use to manufacture our own interface using HTML and Javascript languages. Writing your own application for home automation has never been so easy or so comfortable.

The RaZberry is a tiny daughter card that sits on top of the Raspberry PI GPIO connector not blocking the USB boards. It is powered by the Raspberry PI board with 3.3 V and communicates using UART TTL signals (RX/TX). RaZberry is compatible with all models of Raspberry Pi.

The daughter card hosts a Sigma Designs ZM5101 Z-Wave transceiver module (a so called 5th generation Z-Wave module), an external 32 K SPI flash for network data and a PCBA antenna. Additionally two LEDs are used to indicate certain status of the Z-Wave controller chip. Beside the PCBA antenna there is an option to solder a U.FL connector for external SMA antenna.

The power consumption of the board is typically 18 mA at 3.3 V but can peak up to 40 mA when the chip is transmitting.

RaZberry supports Z-Wave Security S2 and Smart Start technologies.

Compared to the standard firmware design used by almost all Z-Wave transceiver hardware, the RaZberry Shield firmware offers several extensions and enhancements:

• Backup and recovery function including network topology
• Optimised transmitting queue handling to speed up transmitting process
• Firmware update from the OS level in the field
• Trusted Platform module applying strong encryption
• Extended Wakeup Notification to extend battery life time of battery-operated devices in the network
• Advanced statistics about network actual usage
• Allows switching frequencies from software

RaZberry comes with Z-Way software, but it is also compatible with all third party software that uses Z-Wave Serial API. There are firmwares for static controller (for Z-Way and most of third party software) or bridge (for Z/IP).

But if the Z-Way configuration interface included in the device does not satisfy us or we do not know or want to program our own application we can always use free software developed by third parties such as those listed below:

• Domoticz
• Jeedom
• OpenRemote
• Freedomotic

At the same time there are apps for your smartphone or tablet of which we highlight:

• dEOmotics
• Domoticz Lite
• Z-Way for smartphone

The system is based on the Z-Wave Plus chip from Sigma Designs and has a built-in antenna directly on the PCB board. Two LEDs (red and green) are used to communicate information to the user such as data transmission or the inclusion / exclusion status of the controller in the Z-Wave network.

Compatible with virtually all Raspberry models, even old ones, as well as including Model B + and "Raspi" 2 and 3
