2Features
2.1 EMI 2 –EMIZB-141
Real-time measurement and reporting of power consumption
The External Meter Interface 2 serves as a Zigbee interface for your customers’ electronic meters. The External
Meter Interface 2 will collect readings and information from other meters and send data via the Zigbee
communication to appliances in the building. Your customer will then be able to follow their energy consumption
through a display, their computer or mobile phone
Cooperation with any other meters
The External Meter Interface 2 can be used with most electronic power meters. It is compatible with all meters
with an LED indicating power consumption. The External Meter Interface 2 cannot be used in installations with
power production such as PV systems or similar. All data can be collected by an external gateway and stored in a
normal data flash. The Zigbee profile ensures high security in order to protect data and prevent hacking.
The External Meter Interface 2 comes with an optical probe, which is easily attached by a magnet. The cable
length is approximately 800 mm.
2.2 Key features
•LED sensor
•ZigBee OTA cluster for firmware upgrades
•ZigBee 3.0 certified

This cluster provides a mechanism for the management of an end device’s MAC Data Request rate. For the
purposes of this cluster, the term “poll” always refers to the sending of a MAC Data Request from the end device
to the end device’s parent.
This cluster can be used for instance by a configuration device to make an end device responsive for a certain
period of time so that the device can be managed by the controller.

coordinator has to reply with a check-in response.
If it doesn’t find a poll client, it will search again periodically.

3.1.5.5.1 Pulse Configuration
Pulse Configuration represents the number of pulses the meter outputs per unit.
Default value is 1000 imp/kWh, 0x03E8 = 1000 dec.
3.1.5.5.2 Current Summation
Current Summation represents the present value for current summation delivered send to the display.
The value must be scaled according to divider and multiplier.
Example: Preset value = 0,570 kWh
Divider = 1000
Multiplier = 1
That give a Current Summation value of 570
It is important that the Pulse Configuration attribute has been configured correctly before sending the Current
Summation setting because Pulse Configuration is used when calculating the total amount of detected pulses.
3.1.5.6 Commands
The metering cluster support sending 1 command.

The device will use this clusters as a client –provided that a suitable Time Server is available on the network
(most likely on the Gateway).
3.1.9 OTA Upgrade –Cluster id 0x0019 (Client)
The cluster provides a ZigBee standard way to upgrade devices in the network via OTA messages.
When the devices have joined a network it will automatically auto scan for a OTA upgrade server in the network. If
it finds a server an auto bind is created and ones every 6 hour it will automatically send its “current file version” to
the OTA upgrade server. It is the server that initiate the firmware upgrade process.

4MMI user guide
4.1 Menu button
How to get access to the menu button on the EMI:
Open the casing of the device by. The menu button is placed on the PCB.
Pushing the button on a device provides the user with several possibilities.
Pushing the button for longer (push, hold for a few seconds, and release) allows the user to set the device into a
desired mode. A mode change happens at 5 second interval. Below, these modes are illustrated in a state chart.
Idle
EZ mode
Initiator
EZ mode
Target
Factory reset
Push + Hold button
untill led blinks once
Push + Hold button
untill led blinks
continously
Push + Hold button
untill led blinks
twice
Push + Hold button
untill led is off
When cycling through the menu modes, the state is indicated by a number of blinks on the LED. The device is
supporting the ZigBee standardized EZ- mode Commissioning.
4.1.1 EZ mode - Initiator
If the device is not on the network EZ-Mode Network Steering is invoked when the user enters this menu. The led
blinks once every 1 sec until the device has joined the network. If the device was already on the network, it will
broadcast the PermitJoin messages. It is the trust center policy that decides if the device is allowed to join the
network.
When the device has joined the network EZ-Mode Finding and Binding is invoked, and the device start to blink
every 3 sec until a cluster match is found. When a match is found, or the cluster examine is finished the blinking
stops and the device sends a message to the target device to stop the identify time.
The following clusters are support in EZ-mode finding and binding:

•Power configuration cluster
•Metering
The EZ-mode time is hard coded to 3 minutes. This is the Minimum and recommended PermitJoin time broadcast
for EZ-Mode Network Steering and minimum IdentifyTime set for EZ-Mode Finding and Binding. If the user enters
the menu again another 3 minutes is started.
4.1.2 EZ mode - Target
If the device is not on the network EZ-Mode Network Steering is invoked when the user enters this menu. The led
blinks twice every 1 sec until the device has joined the network. If the device was already on the network it will
broadcast the PermitJoin messages. It is the trust center policy that decides if the device is allowed to join the
network.
When the device has joined the network identify mode is invoke and the device start to blink twice every 3 sec
until identify mode is stopped or after the EZ-mode time has expired. If the user enters the menu again another 3
minutes is started.
4.1.3 Factory reset
To allow a device to join a network, one either has to power up a device that has not previously joined a network
or push the button until the Reset To Factory default mode is indicated –and subsequently release the button.
This will cause the device to reset to its factory default state and scan for a suitable coordinator.
4.2 Action on Power On
Generally, all end devices that have not previously joined a network (or have been reset to factory default) will
start up and search for a network with join permit open. In this mode, the Yellow LED will flash while searching for
a network to join.
Once the device has joined the network, is will start scanning for an OTA server, Time server, Poll control client
and a metering client.
If a device has joined a network and is powered down, it will attempt to rejoin this network upon power up. For the
first 30 seconds hereafter, the device will be available for communication. This time can be expanded using the
poll control cluster functionality.

5General network behaviour
5.1 Installation
When the device is factory new and powered for the first time it will start looking for a ZigBee PAN Coordinator or
router to join. The device will scan each ZigBee channel starting from 11 to 26. The LED will flash once every
second until it joins a device.
#Scan mode - 1
Scan all 16 ZigBee
channel until join
network or 15
minutes.
#Sleep mode
MCU is in sleep
mode (Radio off)
15 minutes
#Scan mode - 2
Scan all 16 ZigBee
ch x 1 or until join
network.
~ 30 seconds
#Sleep mode
MCU is in sleep
mode (Radio off)
15 minutes
#Scan mode - 2
Scan all 16 ZigBee
ch x 1 or until join
network.
~ 30 seconds
The device will start up using scan mode 1. To increase battery lifetime when the device is joining a network for
the first time a scan mode 2 will be used after scan mode 1 has expired. Scan mode 1 it will only be executed one
time when the device is powered. If the user invokes EZ-mode it will start scanning the next 3 minutes
In section 5 “MMI” it is explained how to put the device into a join or leave network mode.
Network settings are stored in NV-memory are after a power cycle the device re-join the same network.
If the device has to join a new PAN coordinator the MMI menu supports a “Reset To Factory Fresh Settings”mode.
This will erase all current network information.
5.2 Normal –Keep alive
The device is sending a “keep alive” message to the PAN coordinator every 15 minute to verify that the device is
still connected to the network.
5.2.1 Network lost
If no “keep alive” responses are received 5 times in a row (Worst case 1h15m), the devices will start scanning as
specified in the table below.
When the device is in scan mode the YELLOW LED will flash once every second until it re-joins the network.
According to the ZigBee specification TX is NOT allowed to be enabled all the time and a TX silent period must be
defined.
