The second box of the page allows creating and using a backup. The backup file is stored on the local computer. Please
note that any restore will overwrite the existing network. The restore operation must therefore be confirmed in another
message box. A checkbox defines if the node information in the z-wave chip itself shall be overwritten as well. This
operation result in a possible loss of all network relationships and may require a re-inclusion of devices. Handle with care.
The controller maintenance offers two reset buttons. The “Z-Wave Chip Reboot” restarts the operating system of the Z-
Wave transceiver chip. This can be done safely all the time.
The “Reset Controller” turns the controller back into factory reset. All connections to included devices and all
configurations and settings are lost. This function must be handles with extreme case. An additional dialog requires to
explicitly confirm the function. Only use this function if you know what you do!
The function Remove Failed Node allows removing a node that is no longer communicating with the controller. After
multiple failed communications with a device the controller will mark this device as failed and avoid further
communication. This function finally removes such a device from the network configuration. The drop down list will only
show IDs of failed nodes. If this list is empty this is a good sign!
It is also possible to Replace a Failed node with a new node. This is a combination of removing the failed node and adding
a new node. Using this function makes sure the next included node has the same node ID as the failed node. The drop
down list will only show IDs of failed nodes. If this list is empty this is a good sign!
Battery operated devices are mainly in deep-sleep state and will not answer to communication requests. Hence the
controller will never automatically detect if a certain device is defect or gone. The function “Mark battery device as
failed” manually marks battery-operated devices as failed so that they can be removed or replaces. The dropdown list
shows all battery operated devices but this does not mean that they are failed.
The next two functions deal with the controller role in the network. With ”Learn” this controller can become a secondary
controller in another network. This is only possible if this controller did not include any other device before. Clicking the
“Learn” button turns the controller in a function where it will accept inclusion requests from other controllers. The
controller status dialog on the upper left hand side shows this status. The Learn mode will time out after about 20 seconds
or when the device was included successfully. It is also possible to manually terminate the mode.
The “Change Controller” function actively hands over the role of the primary controller of the network to a controller that
will be included using the normal inclusion process. The controller status dialog shows the mode and its termination.
The “Request NIF from all devices” function is just a convenient way to retrieve a Node Information Frame from all
devices of the network.
The frequency change buttons allow changing the operating frequency of RaZberry. Handle with care! Changing the
frequency may result in malfunction of your network. If you are uncertain about the consequences of this change, don’t
touch the buttons!
The RaZberry hardware can be changed into every valid frequency however the antenna filter used with Z-Wave
transceivers will attenuate the wireless signal for wrong frequencies. At the moment there are three different types of
antenna filters allowing operation in the three frequency groups. Changing the frequency within the line (e.g. from EU to
CN) will not result in attenuation of the signal but will stop any communication in a network already established. Changing
between the lines will not only result in communication problems with existing included devices but also result is severe
attenuation of the wireless signal. It may still be useful to change frequencies for debugging purposes but again: Handle
with care!
