Smart EMU 1 & 3 Bidirectional Meter: User Manual Obtainment Success Story

Smart EMU 1 and 3 bidirectional meter user manual was hard to come by but I finally got it

Many thanks for pdf.
Now the question arises how to connect the Wireless M-BUS module to this meter?

Has anyone been able to read the data from such a meter through the optical head? PGE operator. For me, on 1 try, I got something like the attachment. reading the instructions, I conclude that you may need a password from PGE.

I also have such a counter. How to read data from it correctly with a head? I can see that the character encoding above in the screenshot is not ok

Reads easily through the optocoupler at home
Interestingly, I was at my power plant asking how they relate to reading the basic parameters, i.e. those without a password. They stated that there is no problem, they normally pleasantly surprised me

Can you tell me how to check if this meter has phase-to-phase balancing?

What does the red button do? The one next to the blue ones? There is nothing about this in the instructions

greetings

This button is sealed and is used to access meter functions not available to the user.

So it's physically impossible to even press it?

Is it possible to press, but the pressure will not do anything?

Added after 3 [minutes]:

Will I break the seal by pressing the red button?

On the right side you have a wedge, secured by a seal (in the form of a wire), which would indicate that there is no physical possibility to press the red button without additional interference.

I did this: I pressed the top blue button for more than 5 seconds, the data on the display changes. Then I pressed the blue button again (scrolling through what is displayed) and at one point the inscription "FErrAri5" appeared - that is, confirmation that balancing is. According to the instructions (from the beginning of the thread) the Ferraris method provides phase-to-phase balancing in the meter.
I don't know what is displayed if there is no balancing. Maybe "PErPha5E" as per the instructions?

My emaur3 from Tauron has no balancing and communicates with the inscription "nornAL".

That we should be 100% sure. Do you have the code C.80.0 in the upper left corner of the display?
I am attaching a photo of this setting from my counter.

Thank you for the tip. It seems that my (PGE) balancing is.

You can write, what optical connector you read and what program it is?

Hello.
In the thread "reja" https://www.elektroda.pl/rtvforum/topic3575192.html
they write as in the instructions, i.e.
" The smartEMU3 counter allows you to choose between three energy balancing methods. Two methods are available:
The "algebraic method" "per phase", in which each measuring system of a three-phase meter adds the energy it measures to the appropriate counters, regardless of other systems,
The "vector method" "Ferraris", imitating induction meters; in this method, the energies from the three measuring systems are first summed (including phase energy signs), and then, if the sum of the energy is positive, it is added to the 1.8.x counters, and if negative - to the 2.8.x counters (without the minus sign) ).
Example:
Initial condition of counters:
1.8.0 = 900.0 kWh
2.8.0 = 100.0 kWh
Sample energy consumption:
EL1 = +1 kWh (1 kWh consumption occurred in phase L1)
EL2 = +4 kWh (4 kWh consumption occurred in phase L2)
EL3 = -3 kWh (3 kWh export occurred in L3 phase)
Final state of counters in the "per phase" method:
1.8.0 = 905.0 kWh
2.8.0 = 103.0 kWh
The final state of the counters in the "Ferraris" method:
1.8.0 = 902.0 kWh
2.8.0 = 100.0 kWh
Zakład Energetyczny decides itself how the measurement should be carried out by the meter. "

Energa uses - "Algebraic method" "per phase".
The "vector method" "Ferraris" - is more beneficial for us and so looking at the entries Maco65 and AlekZ does PGE.
In the evening I will check with myself; (PGE connected 8.11).

Adam's program is https://play.google.com/store/apps/details?id=com.REDZelectronics.ZRrobo, I have Android phone via USB. Ask how to what Regards.

Hello, does anyone know what the code c.12.5 means in the smart emu1 counter? Thank you in advance for your answer.

Muczios players You save your ass hard.

And this interface via USB to Android is how it is made? Can you ask for some diagram, where to buy or how to do?

Now the question is how to connect the Wireless M-BUS module to this meter?

I was able to start remote reading from the Apator Smart EMU3 meter at OSD Tauron. The same should work with other smart AMIPlus meters fitted by Tauron (Mitsubishi, Networked Energy Services NES)

1) In the eLicznik Tauron Dystrybucja service, you need to activate the service they call HANPlus (from Home Area Network). Tauron sends the command to activate the wireless M-BUS transmission to the meter via the PLC link. In my case, activation by the website returned an error several times ("HAN activation order - failed"). The hotline is a dead end, no one there is aware of the existence of such a service. I started calling their API manually, the next attempt was successful ("HAN Activation Request - Successful").

2) After successful HANPlus activation, the meter ID and communication decryption key are available on the eCount page.

3) I bought a W-MBUS reading dongle: iM871A-USB. A cheaper alternative, which I haven't checked myself, is to use the DVB-T tuner as a softradia and rtl-wmbus program.

4) I installed wmbusmeters on my Raspberry which reads and decrypts data. The available information is total consumption, instantaneous input power, total energy fed into the grid, instantaneous input power.

5) I store the data in the InfluxDB database, together with the readings from the Fronius inverter, I have a complete set of information about production, consumption, self-consumption and energy given to the grid.

6) PROFIT !!!

How did you do it? I do not see such an option to choose from. Edit: I checked and this option is only available in selected cities.

How did you do it manually? Have you plugged into your installation and sent the commands that your meter reads?

Yes, not everyone in Tauron has this option. You can check the service availability here:

HANPlus activation is available here:

I manually triggered the activation command on the Tauron website (endpoint / ot / hanon ) as if I had clicked on a link. However, the link itself was unavailable for me, I only saw the Deactivation link, even though the activation had failed earlier.

Probably it will be gsm signal strength (remote meter reading)
for example: -55 signal strong, -95 signal weak

Does any of the forum members know how to interpret the readings read from the "window" under the numbers:
1.8.0.1 ..... 1.8.0.6, 2.8.0.1 ....... 2.8.0.6 and the same values as in 2.8.0 ...: 2.8.1.1 .... 2.8.1.1
As far as I read in the forum manual that 1.8.0 is energy bought (for me 8786.5) and 2.8.0 is energy "sold" (for me 12614). These values from .1 to .6 keep me awake at night because I don't know what they mean.
Does PGE have a website where you can read the meter via the net ?!

1.8.0 Active energy input, total kWh A +
1.8.1 Active energy consumed in zone I kWh A + (T1)
1.8.2 Active energy consumed in zone II kWh A + (T2)
1.8.3 Active energy consumed in zone III kWh A + (T3)
1.8.4 Active energy consumed in zone IV kWh A + (T4)
2.8.0 Active exported energy, total kWh A-
2.8.1 Active energy delivered in zone I kWh A- (T1)

These are archival values, depending on how the counter is closed, and it can close, for example, every month or every day, or for any day of the month

if every month on the 1st day of the month then:

1.8.0.1 = state of energy consumed on 1.11.2022
1.8.0.2 = state of energy consumed on 01/10/2022

e.t.c
if the counter will have daily closing, then:
1.8.0.1 = state of energy consumed -1 day back at 0:00
1.8.0.2 = state of consumed energy -2 days back at 0:00
e.t.c

Closing can be any and it is determined by the ZE.

2.8.0.x is the same
