Firmware Version : 1.8
Quick Start
S
This device is a Z-Wave Sensor. Inclusion, Exclusion and wakeup are confirmed by three times quickly hitting the Linking button
(second from left) on the front of the device.
Please refer to the chapters below for detailed information about all aspects of the products usage.
What is Z-Wave?
This device is equipped with wireless communication complying to the Z-Wave standard. Z-Wave is the international standard
for wireless communication in smart homes and buildings. It is using the frequency of 868.42 MHz to realize a very stable
and secure communication. Each message is reconfirmed (two-way communication) 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 transmitter.
Z-Wave differentiates between Controllers and Slaves. Slaves are either sensors (S) transmitting metered or measured data or
actuators (A) capable to execute an action. Controllers are either static mains powered controllers (C) also referred to as
gateways or mobile battery operated remote controls (R). This results in a number of possible communication patterns within a Z-
Wave network that are partly or completely supported by a specific device.
Controllers control actuators
1.
Actuators report change of status back to controller
2.
Sensors report change of status of measured values to controller
3.
Sensors directly control actuators
4.
Actuators control other actuators
5.
Remote controls send signals to static controllers to trigger scenes or other actions
6.
Remote controls control other actuators.
7.
There are two different role a controller can have. There is always one single primary controller that is managing the network and
including/excluding devices. The controller may have other functions - like control buttons - as well. All other controllers don't
manage the network itself but can control other devices. They are called secondary controllers. The image also shows that its not
possible to operate a sensor just from a remote control. Sensors only communicate with static controllers.
