    Study Notes

    Learning Outcomes

    • Ability to install up to five common control devices for radio frequency communication.
    • Understanding that each automation system device has a unique identity.

    Z-Wave Networks: Basics

    • A network requires at least two nodes (devices) that communicate wirelessly through radio waves, similar to mobile phones and televisions.
    • Communication in a Z-Wave network utilizes a specific protocol to filter messages and identify nodes.

    Device Identity in Z-Wave Networks

    • Each node is assigned a unique identification (ID) to differentiate from others within the same network.
    • Z-Wave utilizes two types of IDs:
      • Home ID: A common identity for all nodes, 4 bytes (32 bits) long.
      • Node ID: An individual address for each node, 1 byte (8 bits) long.
    • Nodes with different Home IDs cannot interact, creating isolated networks.
    • There are crucial distinctions between controllers and slave devices:
      • Controllers:
        • Have a factory-set Home ID and a predefined Node ID (typically 0x01).
      • Slaves:
        • Assigned a Home ID by the network and given a Node ID by the primary controller during the inclusion process.

    Z-Wave Network Structure

    • A primary controller is responsible for assigning Home and Node IDs during the device inclusion in the network.
    • Inclusion Process:
      • When a node accepts the primary controller's Home ID, it becomes part of the network.
      • All devices within the same network must have identical Home IDs and unique Node IDs for communication.

    Example of Z-Wave Networks

    • Before inclusion, devices lack assigned Home IDs and cannot communicate due to differing Home IDs.
    • After successful inclusion:
      • All devices share the same Home ID.
      • Each device has its unique Node ID, enabling effective communication.
    • The primary controller synchronizes the network and can include new devices, while the secondary controller cannot include devices but operates similarly to the primary.

    Key Differences in Device IDs

    • Controllers have fixed Home IDs that cannot be changed; slaves are dynamically assigned.
    • Controllers and slaves must maintain unique Node IDs within the network to ensure clear communication pathways.
