Wireless Energy Meter
SKU: SYS-72027-ENL/01
Quickstart
This is a ****
Energy Meter
for
CEPT (Europe).
To run this device please connect it to your mains power supply.
To add this device to your network execute the following action:
Once WEM is installed and connected to the power line for the first time, it
goes into the Idle state. To add WEM to the Z-Wave network, it is first
necessary to put the primary Z-Wave controller into inclusion mode (refer to
the controller user manual). Then, press the WEM button for about 1 second.
WEM enters the Learning state and the LED changes blinking pattern. When the
learning phase ends successfully, WEM enters the Synchronizing state, and then
the Joined, Comm. Ok state. If the clamp is not placed correctly, the Joined,
Clamp Rev. state is entered in place of the Joined, Comm. Ok one. If the
inclusion fails, WEM goes back to the Idle state.
Please refer to the
Manufacturers
Manual for more information.
Important safety information
Please read this manual carefully. Failure to follow the recommendations in
this manual may be dangerous or may violate the law.
The manufacturer, importer, distributor and seller shall not be liable for any
loss or damage resulting from failure to comply with the instructions in this
manual or any other material.
Use this equipment only for its intended purpose. Follow the disposal
instructions.

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
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.
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 Wireless Energy Meter (WEM) is a smart device that performs quasi real- time measurements of the electricity consumption of the home by continuously monitoring the power line.WEM will be installed into the main distribution board, with the amperometric clamp closed around the live wire of a 1-phase system. This allows WEM to measure the line voltage and current, and thus compute the total power and energy consumption of the home.After a simple configuration phase, WEM starts reporting the measurement it takes to a central controller device, such as a home gateway, by means of the Z-Wave wireless technology. Z-Wave is a widespread and interoperable wireless home control technology based on the ITU-T 9959 open standard.WEM has an intuitive user interface, with a LED informing the user about its current state, and a push button to let the user issue the necessary commands. WEM can measure and report the following physical dimensions: Total Accumulated Active Energy (Wh), Instantaneous Active Power (W), RMS Voltage (V), RMS Current (A).WEM allows to fine-tune the way the measurements are performed and reported by means of several parameters, which can be set by most controllers on the market.
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
state. 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.
Reset to factory default
This device also allows to be reset without any involvement of a Z-Wave
controller. This
procedure should only be used when the primary controller is inoperable.
WEM can be reset to the factory default values at any time by pressing the button for about 10 seconds, until the LED turns steadily on. WEM performs the reset operations and the button can be released. When the reset is complete, WEM enters the Idle state. Note that this reset procedure does not remove WEM from a classic Z-Wave controller or in situations where WEM cannot communicate with the Z-Wave Plus controller. Therefore this procedure should be used only when the primary controller is missing or inoperable. To remove WEM from the network under normal circumstances the exclusion procedure should be used.
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.
Inclusion/Exclusion
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.
Inclusion
Once WEM is installed and connected to the power line for the first time, it goes into the Idle state. To add WEM to the Z-Wave network, it is first necessary to put the primary Z-Wave controller into inclusion mode (refer to the controller user manual). Then, press the WEM button for about 1 second. WEM enters the Learning state and the LED changes blinking pattern. When the learning phase ends successfully, WEM enters the Synchronizing state, and then the Joined, Comm. Ok state. If the clamp is not placed correctly, the Joined, Clamp Rev. state is entered in place of the Joined, Comm. Ok one. If the inclusion fails, WEM goes back to the Idle state.
Exclusion
To remove WEM from the network, it is first necessary to put the primary Z-Wave controller into exclusion mode (refer to the controller user manual). Then, press the WEM button for about 3 seconds. WEM enters the Leaving state, and waits for the controller to acknowledge its exclusion. When the exclusion process is complete, WEM goes into the Idle state. If the exclusion process fails, WEM goes back to its previous state.
Quick trouble shooting
Here are a few hints for network installation if things dont work as expected.
- Make sure a device is in factory reset state before including. In doubt exclude before include.
- If inclusion still fails, check if both devices use the same frequency.
- Remove all dead devices from associations. Otherwise you will see severe delays.
- Never use sleeping battery devices without a central controller.
- Dont poll FLIRS devices.
- 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.
Association Groups:

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.
Parameter 10: Avg_Period
_Avg_Period determines the time window used to compute an average over the
line readings. Each unit of Avg_Period is worth 5 seconds. If Avg_Period = 0
no average is computed and the last sample is returned. Note that the maximum
average window coincides with the minimum value of Max_RepInterval. Also note
that a delay of up to the average window can be introduced in returning the
measurements (each measurement is returned only when ready).
Size: 1 Byte, Default Value: 1
SettingDescription
0 – 6 | seconds x 5 |
---|
Parameter 2: Meas_Period
_Meas_Period is the unit period for computing a measurement. WEM checks for
changes in the line measures every Meas_Period. If there are meaningful
changes, a report is sent to the controller. Therefore Meas_Period also
represents represents the minimum reporting interval, i.e. 1/MeasPeriod is
the maximum reporting frequency.
Size: 1 Byte, Default Value: 30
SettingDescription
30 – 120 | seconds |
---|
Parameter 3: Max_Rep_Interval
_Max_Rep_Interval is the maximum time that can elapse without sending a
report. If no meaningful events occur, WEM sends one full measurement every
Max_RepInterval seconds.
Size: 1 Byte, Default Value: 6
SettingDescription
3 – 60 | seconds x 10 |
---|
Parameter 4: Res_Active_Power
_Res_ActivePower is the minimum quantity (resolution) that triggers a report
for active power. It can be used to tune the sensitivity of WEM to changes in
this physical dimension.
Size: 1 Byte, Default Value: 4
SettingDescription
1 – 100 | Watt |
---|
Parameter 5: Res_RMS_Voltage
_Res_RMSVoltage is the minimum quantity (resolution) that triggers a report
for active power. It can be used to tune the sensitivity of WEM to changes in
this physical dimension.
Size: 2 Byte, Default Value: 10
SettingDescription
1 – 1000 | Volt x 0.1 |
---|
Parameter 6: Res_RMS_Current
_Res_RMSCurrent is the minimum quantity (resolution) that triggers a report
for active power. It can be used to tune the sensitivity of WEM to changes in
this physical dimension.
Size: 2 Byte, Default Value: 10
SettingDescription
1 – 1000 | Ampere x 0.01 |
---|
Parameter 8: Clamp_reversed
_Clamp_Reversed is a read-only parameter that the controller can query to
learn about the current placement of the clamp. During the measurement phase,
WEM checks whether the clamp has been placed correctly or reversed (with
regard to phase rotation). In the latter case, WEM notifies the user with a
different blink pattern and stores this information into the Clamp_Reversed
parameter. The clamp is placed correctly if Clamp_Reversed = 0 and is reversed
if Clamp_Reversed = 1. If ClampReversed = 0xFF a fault occurred and it was
not possible to detect the clamp position.
Size: 1 Byte, Default Value: 255
SettingDescription
0 – 255 | only 0,1, 255 (0xFF) are valid |
---|
Parameter 9: Enable_CRC16
_Enable_CRC16 provides for an extra layer of redundancy in order to protect
low bit rate transmissions against radio channel errors. This applies to the
reports and frames sent spontaneous by WEM. Requests from the controller are
always answered as asked. WEM will send CRC16 encapsulated frames to the
associated node if this has proved to support it and EnableCRC16 is set to 1.
Otherwise, reports will be sent with no extra CRC16 encapsulation.
Size: 1 Byte, Default Value: 1
