What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This
device is suited for use in the region mentioned in the Quickstart section.

Z-Wave ensures a reliable communication by reconfirming every message ( two- way
) and every mains powered node can act as a repeater for other nodes
( meshed network ) in case the receiver is not in direct wireless range of the

This device and every other certified Z-Wave device can be used together with any other
certified Z-Wave device regardless of brand and origin
as long as both are suited for the
same frequency range.

If a device supports secure communication it will communicate with other devices
secure as long as this device provides the same or a higher level of security.
Otherwise it will automatically turn into a lower level of security to maintain
backward compatibility.

Product Description

The Domitech BulbZ is a Z-Wave controllable and fully-dimmable , instant- on LED screw-in light bulb that provides gorgeous soft-white illumination (2700K). Equivalent to a 60-watt incandescent bulb and using only nine (9) watts of energy, BulbZ is estimated to save approximately 140 EU throughout its average lifespan. The Bulb can be used even in two-wire electrical systems where an installation of a standard Z-Wave switch or dimmer will fail. As with all Z-Wave products, BulbZ operates at the standard 868.42 MHz frequency, acts as Z-Wave repeater and gives users the convenience of wirelessly controlling lighting from a Z-Wave hub or controller.

Prepare for Installation / Reset

Please read the user manual before installing the product.

In order to include (add) a Z-Wave device to a network it must be in factory default
Please make sure to reset the device into factory default. You can do this by
performing an Exclusion operation as described below in the manual. Every Z-Wave
controller is able to perform this operation however it is recommended to use the primary
controller of the previous network to make sure the very device is excluded properly
from this network.

Safety Warning for Mains Powered Devices

ATTENTION: only authorized technicians under consideration of the country- specific
installation guidelines/norms may do works with mains power. Prior to the assembly of
the product, the voltage network has to be switched off and ensured against re-switching.


Just screw the bulb into a standard E27 light bulb socket.

Device Reset For device reset the device must be turned on and off 4 times in a row within 4 seconds.


On factory default the device does not belong to any Z-Wave network. The device needs
to be added to an existing wireless network to communicate with the devices of this network.
This process is called Inclusion.

Devices can also be removed from a network. This process is called Exclusion.
Both processes are initiated by the primary controller of the Z-Wave network. This
controller is turned into exclusion respective inclusion mode. Inclusion and Exclusion is
then performed doing a special manual action right on the device.


Turning on the power switch on the wall includes the device. For exclusion the device must be turned on and off 4 times in a row within 4 seconds


Turning on the power switch on the wall includes the device. For exclusion the device must be turned on and off 4 times in a row within 4 seconds

Product Usage

The device can be controlled from the legacy wall switch and in parallel from any Z-Wave wireless controller. It can be dimmed and switch on and off. In case the legacy wall has turned off the bulb it can not be turned on by wireless command. To prevent this a two times off/on switching sequence on the wall switch within 2 seconds (switch remains in ON-position after this) will turn off the lamp be keeps it powered. All other mixed combinations of controls are possible:

  • * Wall Switch ON => Lamp ON => Wall Switch OFF => Lamp OFF
    • Wall Switch ON => Lamp ON => Z-Wave OFF => Lamp OFF => Z-Wave ON => Lamp ON
    • Wall Switch ON => Lamp ON => Z-Wave DIM => Z-Wave OFF => Lamp OFF => Z-Wave ON => Lamp dimmed
    • Wall Switch ON => Lamp ON => Z-Wave DIM => Wall Switch OFF => Lamp OFF => Wall Switch ON => Lamp dimmed
    • Wall Switch ON => Lamp ON => Z-Wave OFF => Lamp OFF => Wall Switch OFF/ON => Lamp ON
    • Wall Switch OFF => Lamp OFF => Wall Switch ON => Lamp ON
    • Wall Switch OFF/ON/OFF/ON => Lamp OFF => Z-Wave ON => Lamp ON
    • Wall Switch OFF => Lamp OFF => no Z-Wave operation

Node Information Frame

The Node Information Frame (NIF) is the business card of a Z-Wave device. It contains
information about the device type and the technical capabilities. The inclusion and
exclusion of the device is confirmed by sending out a Node Information Frame.
Beside this it may be needed for certain network operations to send out a Node
Information Frame. To issue a NIF execute the following action:

In factory reset the device will issue a NIF every time when powered.

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

  1. Make sure a device is in factory reset state before including. In doubt exclude before include.
  2. If inclusion still fails, check if both devices use the same frequency.
  3. Remove all dead devices from associations. Otherwise you will see severe delays.
  4. Never use sleeping battery devices without a central controller.
  5. Dont poll FLIRS devices.
  6. Make sure to have enough mains powered device to benefit from the meshing

Association – one device controls an other device

Z-Wave devices control other Z-Wave devices. The relationship between one device
controlling another device is called association. In order to control a different
device, the controlling device needs to maintain a list of devices that will receive
controlling commands. These lists are called association groups and they are always
related to certain events (e.g. button pressed, sensor triggers, …). In case
the event happens all devices stored in the respective association group will
receive the same wireless command wireless command, typically a ‘Basic Set’ Command.

Explanation of Z-Wave specific terms

  • Controller — is a Z-Wave device with capabilities to manage the network.
    Controllers are typically Gateways,Remote Controls or battery operated wall controllers.

  • Slave — is a Z-Wave device without capabilities to manage the network.
    Slaves can be sensors, actuators and even remote controls.

  • Primary Controller — is the central organizer of the network. It must be
    a controller. There can be only one primary controller in a Z-Wave network.

  • Inclusion — is the process of adding new Z-Wave devices into a network.

  • Exclusion — is the process of removing Z-Wave devices from the network.

  • Association — is a control relationship between a controlling device and
    a controlled device.

  • Wakeup Notification — is a special wireless message issued by a Z-Wave
    device to announces that is able to communicate.

  • Node Information Frame — is a special wireless message issued by a
    Z-Wave device to announce its capabilities and functions.
