About

Z-Wave is a wireless communications standard. The technology uses a low-power RF radio embedded or retrofitted into building electronics devices and systems. Currently there are nearly 1000 different Z-Wave products that all work together so you can choose the products that are right for your project. The main benefits of Z-Wave are:

  • Easy to install
  • Does not require any rewiring - no new wires!
  • Any product with Z-Wave on the box works with any other
  • Affordable - get started with minimum investment and easily add on more products
  • Reliable - Over ten years in the market
  • Secure - same encryption as online banking
  • Lots of choices - styles, price points, colors, etc
  • Already 20 million products in homes worldwide
  • Biggest brand names use Z-Wave
  • 9 out of 10 leading security companies use Z-Wave

    You can find all device information in Z-Wave device database

Z-Wave software along with devices is great for home automation in old (existing) buildings.

Network Configuration

Main Z-Wave node displays an overview of a Z-wave network, where all the included devices and statuses are shown.

Z-Wave configuration

Picture 1: Z-Wave node

Devices:

  • Discovery - Starts the discovery process and adds devices to Z-Wave node.
  • Inclusion - Including a new device.
  • Exclusion - Excluding an existing device.
  • Controller:
    • Remove Failed Node - Removes broken Z-wave device from the list.
    • Soft Reset - Reboots the USB stick. Useful if USB stick freezes. No data will be lost.
    • Reset to Default - Resets the Z-Wawe controller to factory defaults. All included devices will be erased from the Z-Wave controller! NOTE: Reset to default only resets the Z-Wave controller if you want to include devices back or to another controller, you need to Exclude them first.
  • Settings:
    • General - Displays basic information about device.
    • Association - Form for associating devices with controller or with other Z-Wave devices.
    • Parameters - Special settings for a device.
    • Info - Z-wave product manual from Z-Wave Alliance database.
  • Rename - Renames selected node.
  • Delete - Deletes selected node, user will have to confirm again before deleting.

Every tab has more details in further chapters.

Z-wave devices list:

  • ID - A unique ID that is assigned to a device when included to the network.
  • Name - Name of the device. If a device already exists in the configuration it will display the name from the configuration. If not, it will be assigned a default name which is a combination of DeviceType and Node ID(ex. BinarySwitch5)
  • Device Type - Type of the device.
  • Listening - Devices powered with a battery are set as not listening and devices powered any other way are set as listening.
  • Status - Current status of the device.
    Possible statuses:

    • Waiting- Waiting for device info.
    • Sleeping - A device that does not respond and is categorized as a sleeping device (device that is battery powered). Check the device documentation for how to wake up a device.
    • Unknown - Did not get any information about the device. It is probably unreachable.
    • Imported - Device with the same node id already exists in the configuration and will not be imported.
    • Incompatible - Device with the same node id already exists in the configuration but it is not the same type. It will not be imported.
    • Ready - Device is successfully discovered and ready to be used.

Inclusion

Inclusion is a process of adding a new device to the Z-Wave network. The number of times an inclusion button on the device must be pressed varies from device to device. Please check the device documentation first.

Inclusion in bOS Configurator

  1. Insert USB stick in USB port.
  2. Add a new Z-Wave node to the configuration.
  3. On the right side in Settings tab enter your COM port number and set Enabled to true.
  4. Click Inclusion button in the Devices toolbar. This will start the inclusion procedure. Put the device in range of the Z-wave Controller. Then press the inclusion button on the device. In a few seconds device information should appear. After successful inclusion, associate the device with Z-Wave controller and set the device parameters.
  5. Step 4 must be repeated for every device you wish to include.

Inclusion with USB stick

Not all USB sticks have this functionality. Example of a USB stick with an inclusion/exclusion button is the Aeotec Z-Stick Series 2.

The USB stick needs to be in close vicinity (less than 1m or 3ft.) of the device you wish to add. First press the inclusion button on the USB stick then press the button on the device. When you finish including all the devices follow the following steps:

  1. Insert USB stick in USB port.
  2. Add a new Z-Wave node to the configuration.
  3. On the right side in Settings tab enter your COM port number and set Enabled to true.
  4. Click Discovery button in the Devices toolbar. This should automatically start the discovery process. In a few seconds the list should be populated with devices you have added previously.

Exclusion

Exclusion is a process of removing a device from a Z-wave network. Not all USB sticks have this functionality. Example of a USB stick with an inclusion/exclusion button is the Aeotec Z-Stick Series 2.

Exclusion with USB stick

The exclusion depends on the device and the USB stick. Please check their documentation for details.

Exclusion in bOS Configurator

  1. Select the main Z-Wave node.
  2. Click on the Exclusion button in the Devices toolbar. This will start the exclusion process, then press the button on the device.
  3. If a device was successfully excluded it should be removed from the bottom list.

Note: The number of times an inclusion button on the device must be pressed varies from device to device. Please check the device documentation first.

Device Configuration

You can additionally configure a device by clicking on the device node and click the Settings button in the top left corner of the Settings tab. The newly opened form contains settings that are available for the device. The number of tabs in the form may vary depending on the device. For more details about a device please refer to the device manual or under the info node.

Quick overview of the tabs:

  • General - General version information about the library, protocol and application. May be used to check if firmware is up to date.

  • Association - This is a very important function of Z-Wave. It enables linking two devices (ex. PIR sensor and a light switch) to work independently from the USB stick. Assign a device (Node ID ) to an association group by clicking Set button. To get devices assigned to the group click Get button. You can also remove a device from a group by selecting it from the list and clicking Delete. For what a specific group does and how many they are please refer to the device documentation.

  • Info - Info tab displays Z-wave product manual from Z-Wave Alliance database.

Multilevel sensor configuration

This instructions are for devices with a multislevelsensor command class. Click on the multilevel sensor and from Sensor Type choose the appropriate sensor.
