Interoperability

How does Z-Wave ensure Interoperability?

Benefits of Interoperability

EVERY Z-Wave device is defined by:

• Basic Device Class
• Defines role in the network, either a Controller or Slave
• Generic and Specific Device Classes
• Defines the type and functionality of a device
• i.e. Device says I am a Dimmable Light Switch
• Command Classes
• i.e. Controller asks the Light Switch how bright are you? The Light Switch says I am now at 100%.

• Enables end-user to combine products from different vendors
• Enables manufacturers with different competence areas to bring together a complete solution
• Provides future-proof investments
• Creates a platform for joint promotional activities

Device Classes

• Generic Device Classes
• Minimum functionalities required to realize a device
• Set of mandatory Command Classes the device supports and controls

• Specific Device Classes
• Tailored for specific uses
• Inherits all mandatory Command Classes from the Generic Device Class
• Specifies additional mandatory and optional Command Classes the device support
• Specifies mapping into Basic Command Class

YOUR Home ID

• The easiest way to find YOUR Home ID is to learn in a Z-Wave device, trigger an event from your panel, and watch your Zniffer.

• Locks are absolutely the easiest because they are the least “chatty”.
• They use an encapsulated security message that is easy to spot and then go back to sleep.

Thermostats

Battery Operated Devices are normally sleeping, they use a Wake Up Command Class to Wake Up and Report.

Light Switches

Dimmer Switches

Power Operated Devices (plugged in to AC power) do not use a Wake Up Command, as they do not go to sleep to conserve battery life.

Command Classes

Command Classes are a collection of functionally related commands

• Fundamental building blocks for a specific function
• A device can have several functionalities and therefore support one or more Command Classes
• The majority of Command Classes comprises of a SET, GET and REPORT command structure
• To support a Command Class, all commands belonging that class must be supported

If you ever contact Mariusz for Z-Wave help,

he will ALWAYS ask for a Zniffer trace first.

This is how important the Zniffer trace is.

"The successful interworking of multiple products from multiple manufacturers, for multiple applications, that may be used on multiple versions of Z-Wave."

Home ID - A unique 32 bit number for each Z-Wave network

The Home ID of a Z-Wave network is based on the Home ID of the controller that initiated the Z-Wave network

Node ID – An 8 bit number for each node on the Z-Wave network

There is only 1 Node ID number within each Z-Wave network

Node IDs are assigned to the nodes by the controller that creates the network

One Z-Wave network can have up to 232 Nodes

A Z-Wave node will only respond to Z-Wave frames containing the Home ID and a Node ID that has been assigned to the node
