EVR_ST814
Z-Wave Temperature and Humidity
Sensor
Firmware Version : 1.8
Quick Start
SThis 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 actuators1.
Actuators report change of status back to controller2.
Sensors report change of status of measured values to controller3.
Sensors directly control actuators4.
Actuators control other actuators5.
Remote controls send signals to static controllers to trigger scenes or other actions6.
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.

Product description
The ST812 is a combined temperature/humidity sensor which is designed for both - desktop use or wall mountable. The device has
a local LCD display which either shows the temperature or the humidity. Four buttons allow to switch between minimim, maximum
or actual values, humidity versus temperature and Fahrenheit versus Celsius. The device can report its values via Z-Wave and
allows to set trigger level for direct control of other Z-Wave devices, when the measured value hits the trigger point. This makes
the ST814 a very powerful and flexible tool to measure environmental values and control device within a Z-Wave network.
Batteries
The unit is operated by batteries. Use only batteries of correct type. Never mix old and new batteries in the same device. Used
batteries contain hazardous substances and should not be disposed of with household waste!
Battery Type: 3 * AA

2. Put the 3 * AA 1.5V batteries in the battery compartment.
3. For wall mounting use mount plate and the screws.
4. Refit the device to the back cover and secure with the fixing screw.
5. For table placing insert the stand into the hole on mounting bracket and turn 90 degrees lockwise.
6. Once snapped in place, the detector can be placed on a shelf, table or other surface where the temperature and humidity
measurements are desired.
Behavior within the Z-Wave network
I On factory default the device does not belong to any Z-Wave network. The device needs to join an existing wireless network to

3 (c) 2012 Z-Wave Europe GmbH, Goldbachstr. 13, 09337 Hohenstein-Ernstthal, Germany, www.zwaveeurope.com
communicate with the devices of this network. This process is called Inclusion. Devices can also leave a network. This process is
called Exclusion. Both processes are initiated by the primary controller of the Z-Wave network. This controller will be turned into
exclusion respective inclusion mode. Please refer to your primary controllers manual on how to turn your controller into inclusion
or exclusion mode. Only if the primary controller is in inclusion or exclusion mode, this device can join or leave the network.
Leaving the network - i.e. being excluded - sets the device back to factory default.
If the device already belongs to a network, follow the exclusion process before including it in your network. Otherwise inclusion of
this device will fail. If the controller being included was a primary controller, it has to be reset first.
Make sure that your Z-Wave Controller is in the Inclusion-/Exclusion-Mode. Quickly click three times on the Linking button on the
front of the device to confirm the process.

3.1 Programming Z-Wave
Z-Wave's Groups (Association Command Class Version 2)
The Temp./Humid. Detector can be set to send reports to or control associated Z-Wave devices. It supports two association groups
with one node support for Grouping 1 and three nodes support for Grouping 2.
Grouping 1 includes POWER_APPLIED, SENSOR_MULTILEVEL _REPORT, ALARM_REPORT and BATTERY_REPORT_COMMAND.
Grouping 2 includes BASIC_SET.
Grouping 1
POWER_APPLIED command
Whenever power is applied, it will send ALARM_REPORT command to the nodes of Grouping 1 to inform the devices that the
detector is powered up.
MULTILEVEL_SENSOR_REPORT
The detector will emit SENSOR_MULTILEVEL_REPORT to inform the nodes of Grouping 1 automatically its current temperature and

7 (c) 2012 Z-Wave Europe GmbH, Goldbachstr. 13, 09337 Hohenstein-Ernstthal, Germany, www.zwaveeurope.com
humidity. Refer to the section of Z-Wave's Configuration for settings of auto report configuration.
Low Battery Report
When the battery level of the detector drops to an unacceptable level, the Low Battery icon will appear on the LCD and the
detector will emit ALARM_REPORT command to the nodes of Grouping 1.
Grouping 2 (Max. Node = 3)
When the detector is triggered, it will emit BASIC_SET_COMMAND to the nodes of Grouping 2.
Please refer to the table below for the setting of basic set command.
Note:
If the Z-Wave mode is OFF, no command will be sent even the Temp./Humid. Detector has been triggered. If Z-Wave mode is ON
and the detector has been triggered, the device will send commands to nodes of Grouping 2.
If the Z-Wave mode reading is 00, it implies no node ID has been allocated by Z-Wave Controller. Please execute inclusion mode as
described in the manual.
4. Beep Tone
To set the beep tone, press Select Mode button and select MODE 8. The Beep Tone icon flashes. Press Max. for ON and Min. for
OFF. If it is ON, a beep tone will be sounded whenever a button is pressed; 4 continuous beep tones will be sounded for 1 second if
the detector has been triggered.
Wakeup Intervals - how to communicate with the device?
W This device is battery operated and turned into deep sleep state most of the time to save battery life time. Communication with
the device is limited. In order to communicate with the device, a static controller C is needed in the network. This controller will
maintain a mailbox for the battery operated devices and store commands that can not be received during deep sleep state.
Without such a controller, communication may become impossible and/or the battery life time is significantly decreased.
This device will wakeup regularly and announce the wakeup state by sending out a so called Wakeup Notification. The controller
can then empty the mailbox. Therefore, the device needs to be configured with the desired wakeup interval and the node ID of the
controller. If the device was included by a static controller this controller will usually perform all necessary configurations. The
wakeup interval is a tradeoff between maximal battery life time and the desired responses of the device.
Quickly clicking three times on the Linking button on the front of the device will issue a Node Information Frame and keep the
device awake to receive configuration commands.
It is possible to set the node ID to 255 to send wakeup notifications as broadcast. In this mode device takes more time to go to
sleep and drains battery faster, but can notify all it's direct neighbors about a wakeup.
Node Information Frame
NIF The Node Information Frame 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.
Quickly clicking three times on the Linking button on the front of the device will issue a Node Information Frame and keep the
device awake to receive configuration commands.
Associations
A 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

8 (c) 2012 Z-Wave Europe GmbH, Goldbachstr. 13, 09337 Hohenstein-Ernstthal, Germany, www.zwaveeurope.com
pressed, sensor triggers, ...). In case the event happens all devices stored in the respective association group will receive a
common wireless command.
Association Groups:
1 Battery Status and Sensor Report (max. nodes in group: 1)
2 Sensor Triggered (max. nodes in group: 3)
Configuration Parameters
Z-Wave products are supposed to work out of the box after inclusion, however certain configuration can adapt the function better
to user needs or unlock further enhanced features.
IMPORTANT: Controllers may only allow configuring signed values. In order to set values in the range 128 … 255 the value sent in
the application shall be the desired value minus 256. For example: to set a parameter to 200 it may be needed to set a value of
200 minus 256 = minus 56. In case of a two byte value the same logic applies: Values greater than 32768 may needed to be given
as negative values too.
