RasPi and Z-Wave Interface

Connecting a RasPi to a Z-Wave network requires the use of a Z-Wave USB dongle. One such device made by Aeon Labs, called the Z-Stick, is shown in Fig. 7–10.

Figure 7–10 Aeon Labs Z-Stick.

The Z-Stick incorporates a Zensys module and a USB interface chip along with some additional firmware to make the two components work together. It also has an internal rechargeable battery that enables the storage of firmware updates and configuration data. The Z-Stick has three operating modes that you should know:

1. Inclusion—This mode adds or includes Z-wave devices into the network. To add a device:

a. Unplug the Z-Stick from the USB connector.

b. Press the large button on the Z-Stick. The Z-Stick LED will start to blink slowly.

c. Go to the device that you wish to add (while continuing to press the large Z-Stick button) and press and release the device’s button.

d. The Z-Stick LED will blink rapidly for several seconds, then glow steadily for three seconds, and finally return to a slow blinking state. The device has been added to the network.
