Z-Wave addressing
Z-Wave has a fairly simple addressing mechanism compared to Bluetooth and Zigbee protocols. The addressing scheme is kept simple because all attempts are made to minimize traffic and conserve power. There are two fundamental addressing identifiers that need definition before proceeding:
- Home ID: This is a 32-bit unique identifier that is preprogrammed in controller devices to assist with identifying Z-Wave networks from each other. During network start, all Z-Wave slaves have a home ID of zero and the controller will systematically populate the slave nodes with the correct home ID.
- Node ID: This is an 8-bit value that is assigned to each slave by the controller and provides addressing of slaves in the Z-Wave network.
