With the EMM.630 MID, 40 values can be measured, including 6 counter readings:
1. Import active energy in kWh
2. Export active energy in kWh
3. Total active energy through the meter = import + export in kWh
4. Import reactive energy in kVAh
5. Export reactive energy in kVAh
6. Total reactive energy by the meter = import + export in kVAhr
• read the meter reading below as follows: 0000 0314.14 kWh
So stick the 2 numbers behind each other !!
• In our logger both counter readings (import + export) are logged separately
• To know a (Belgian ferraris) reversing meter reading, one must in fact just take the difference: import – export = reversing meter
LoWi, MiLo, MEMo are web servers with a local fixed IP address and their own port number, example ‘192.168.0.123:8081’.
Every device within the local network can surf to web pages on the web server via this IP address.
To now also have access to local web servers from outside the house, you have to set up port forwarding in your internet modem.
The way to do this is different for every modem, but the principle is basically the same everywhere, we show how to do it for a telenet modem:
Note: the advantage of a telenet modem is that its IP address remains unchanged for a longer period (several months). With modems with internet via SIM card, this IP address can change within a few hours and port forwarding makes little sense there.
During the configuration of your web server you have set a fixed IP address, a port number and also a login in password for access from the country house and we keep this at hand.
Surf to ‘my telenet’ and log in to your account. Go to your ‘home network’, then ‘modem details’ and then ‘advanced settings’.
In the tab ‘Network‘ you can read the IP address of your modem, write down this IP address
in the next tab ‘IPv4 Firewall and Portforwarding‘ you provide your local ip address and the port number. Also check your firewall settings. If you want to be able to upgrade your LoWi or MiLo then ‘Fragmented IP packets’ must be set to ‘allow’. Then save everything and from now on you can surf from outside to your LoWi web server via the IP address of your modem followed by the port number of your web server. example: http: //111.222.333.444.8082, and of course login and password if you are surfing from the outside.
Note: adjustments to the configuration of LoWi or MiLo can only be made from the local network, not from the outside. This is possible with the MEMo2 webserver if you are logged in as an administrator.
2-Wire has a number of different 3-phase meters (EMM.630 series) either with direct current passage or with current clamps. These 3-F meters are mainly intended for 3P4 or 3x380V + N connection, but can also be used as a 3x230V (3P3) meter or as a mono-phase meter (1P2).
Measured values: On the display of these meters you can read a number of measuring variables such as voltage, current, power, frequency, power factor, … per phase or as a total over the three phases. Of those many parameters, MEMo registers (as a snapshot) voltage, current, power in KW, reactive power in KVar, power factor and that for each of the 3 phases. These measurements are stored for up to 3 years on SD with 1 minute resolution.
Daily graphs are displayed on the web server per phase, voltage and current and power, so we arrive at 3 graphs per 3-phase meter. (see bitmap below)
The current power of each phase is also shown at the top of the collapsed graph
Meter readings: In addition to measuring variables, there are also increasing consumption counters which register the total consumption (active and reactive) over the 3 phases. MEMo registers the active consumption meter readings IMPORT and EXPORT (= injection) every minute expressed in kWh. These counter readings are stored on SD for up to 3 years
In the web server graphs we do not show these meter readings, but each time the one-hour difference between two successive meter readings and that for the 2 flow directions, namely the consumption (IMPORT) over one hour in kWh, and the injection (EXPORT) over one hour in kWh.
The daily consumption (= meter reading 00.00Hr – meter reading 24.00H) and annual consumption (= Meter reading 1 January – meter reading today) is shown as a value at the top of the closed graph
In the monthly charts, the daily consumption together with the energy costs are shown.
Figure. In the figure below, only the Phase 1 daily graph is expanded. The curves show voltage, current, power of phase 1, the blue graph shows the hourly consumption over the 3 phases together, calculated as the one-hour difference between two successive meter readings expressed in kWh.
Each website takes up server space on the internet and gets its own IP address. To find out that IP address, you can use the Ping command on your computer.
Website IP address: Go to the Windows Start button and type “cmd” or “Command Prompt”. Then press enter. You now get a black window where you can enter MS-DOS commands.
In that window, enter the command “ping”, followed by the name of the website whose IP address you want to find out. Then press enter again. For example, the search would return: Ping to 2-wire.be [126.96.36.199] with 32 bytes of data.
The numeric address in parentheses is the website’s IP address.
Free IP address: In the same way you can enter your own local IP address (for example, the IP address proposed by the IP server scanner tool) so you can immediately see whether it is free or not. In the example below you can see that Pinging to [192.168.1.122] is busy and that Pinging to [192.168.1.117] is free.
You can access the web page of your LoWi, MiLo or MEMo via the web browser on your computer, tablet and smartphone. By adding this to the home screen of your tablet or smartphone you have quick and direct access to your energy consumption and energy costs.
You can add 2-Wire Energy monitor to your home screen and it looks like an app. This works as follows:
iOS (iPad and iPhone)
Open your web page from your LoWi, MiLo or MEMo web server
Click on the Share button in the web browser (square with arrow up)
Then click Add to Home Screen
Then click Add
Open your web page from your LoWi, MiLo or MEMo web server
Click on the Share button in the web browser (three dots)
Then click Add shortcut to the home screen
Windows Phone and Windows Mobile
Open your web page from your LoWi, MiLo or MEMo web server
Click in Internet Explorer on the Share button (three dots)
Then choose Pin to start screen
Upgrading a web server can be done either be software-based via the configuration page, either hardware-wise via the pushbuttons on the web server. In the video below, we show you how to do it through software.
Op de webserver vind je bovenaan 2 drukknoppen ( SW1 :Reset en SW2: Clear) en met deze 2 toetsen zijn er 4 combinaties mogelijk:
Drukken toetsen tijdens het runnen: UPGRADE
Drukken toetsen tijdens het opstarten spanning: RESET
Ontdekt je fouten op de website, of is er geen enkele toets die nog reageert, zelfs na ‘refresh page’, dan is er mogelijk een fout geslopen bij het inladen van het
Als dit in orde is, dan doe je met de rechtse drukknop (toets 2) net hetzelfde: blijven drukken tot het flashen stopt en beide leds continue branden, dan pas loslaten toets. Nu moeten de leds ook 15 tot 20 sec branden en nadien begint de rechtse led heel snel te knipperen. Nadien zal de led een 3tal seconden continue branden en dan uit gaan. Alles oke !!! Wanneer deze zaken gebeuren zoals beschreven, probeer dan opnieuw ‘refresh page’ en log in. Op de pagina configuration/settings kan je nog even testen naar de firmware versies.
Toets 1 (SW1=reset, links, kortst tegen voedingsconnector)
Procedure: Spanning van de WS500 uitzetten, 5 seconden wachten, toets 1 ingedrukt houden, spanning aanzetten, en blijven drukken tot de led begint te knipperen. Blijf nog een 3tal seconden drukken tot de led stopt met knipperen en laat dan de toets los. De wis‐procedure kan ca 60 seconden duren, en de WS500 is klaar als de led uit gaat.
Toets 2 (SW2 Clear, volledig rechts):
Procedure: Spanning van de WS500 uitzetten, 5 seconden wachten, toets 2 ingedrukt houden, spanning aanzetten, en blijven drukken tot de led begint te knipperen. Blijf nog een 3tal seconden drukken tot de led stopt met knipperen en laat dan de toets los.
De wis‐procedure kan ca 3 seconden duren, en de WS500 is klaar als de led uit gaat.
Je moet nu ‘surfen’ naar het standaard IP‐adres: 192.168.0.123:8080 en login, password zoals beschreven de handleiding in deel 8 ofwel het IP adres vinden en eventueel aanpassen via de IP serverscanner ( zie /producten/datasheets/ip scanner)
Opmerking: De modules PC.080, EC.441 , RG.016 kunnen enkel vanuit de webserver worden geüpgraded.
Through the server scanner, a free software application (download via the 2-wire web site) you will find the IP address of your web server. The found IP address and port number 8080, should be typed in the web browser (example: 192.168.1.141:8080) to go to the login page of your web server.
Internet: The Web server does not require Internet connection except for firmware updates, email notification and ftp-client functionality. The PC or tablet requires an Internet connection at the first boot in order to load the necessary charts in its cache.
Other problems reported by users:
Change IP address to DHCP: if DNS address is not working properly, a new IP address is assigned and is linked to the Web server. Preferred DNS address: 188.8.131.52 (Telenet 192.168.0.1 did not work)
The module has 8 inputs and PC.080 EC.441 module has 4 inputs which can all be used as a pulse input. In order to connect a water meter on this input, it is important that the water meter is provided with a module that functions as a pulse output. In many modern water meters is the option to connect to a pulse sensor already present. You can optionally order the pulse module to the meter supplier, and afterwards it can be connected to a free input of the EC.441 or PC.080 module.
The following types can be ordered via the webshop on this site:
Water probe S02
This is a cylindrical reed switch with 2 cm wire. This type is compatible with the V100 type of meter Elster.
Installation: On the meter, there is a black plastic cover attached with two screws. It is sufficient to remove it and slide in the probe into the bore. Afterwards you can attach the probe with a cable tie. Then connect the red wire to the plus input and the black wire to the minus input of the 2-wire module.
Water probe Elster PR6
This is a cylindrical reed contact with 50cm wire. This type is compatible with the Elster V200 type meter: PR6_PR7_NL
Extra water meter in series
If your water meter does not have the option of installing a pulse generator, you can install a 2nd meter with pulse output or water meter with modbus output (see / products / assortiment / … on this site) in series with the existing water meter.
Configuration two water meters:
In the configuration, go to the module to which the meter is connected. The coupled input you give a name to your output, choose “counter” mode, the unit m³ / hr and indicate how many pulses are required for 1 m³.
The 2-wire modules are installed by the electrician in the fuse box and then the server is connected to the local network.
Through the webservers web pages, the names of consumers, consumption units, energy prices, network setting, ... can easily be configured via tablet or PC.
After the configuration every minute all measured data is read and stored in the web server. All consumption values and energy costs are now accessible via Web browser.
