OneMeter Energy Consumption Meter: User Experiences with Optical Port Plug-In & PV Stats

Good morning,

I would like to ask if any of you have heard of a device called OneMeter?
It is a small device used to control energy consumption - a small cap that is put on the optical port in the meter. This "plug-in" reads the meter data at 15-minute intervals, stores it and keeps detailed statistics on the energy consumption. It can also work with a bidirectional meter, making full graphs of the energy obtained and given to the grid - this is what I'm particularly interested in in terms of photovoltaics.
Has anyone ever had contact with the device or is its owner?
I would love to hear from you about how OneMeter works, if there are any

In meters installed by ZE the optical port will probably be completely disabled or the access via this interface will be password protected.
Sometimes there are two passwords. Knowing one allows you to read the consumption and the other allows you to change the configuration. I do not know how it is now, but the ZE used to have a very restrictive policy in this regard. So the less the user can do the better.
An alternative solution is to count the flashes of the LED diode located in the meter. Usually, however, there is only one such diode for active energy. So there is no way to distinguish between energy produced and consumed.
See also a product for a similar application: iNode Energy Meter.

Hello,

I have just been delivered the mentioned device, ie OneMeter in the Home version. I purchased the device due to the freshly launched FV installation.
According to the information on the manufacturer's website, a device with Android ver min 4.3 is required.
The device to which I wanted to connect is equipped with Android 4.4.2 (there is no possibility of upgrading) - despite this, I was not able to install the app from the Google Play store.
I contacted the producer (I feel stupid after their working hours) and I was assured that the developer would check what was wrong and let me know tomorrow.

I am concerned about the fact that a few days earlier I was assured that if I owned the device, I would get API access and be able to download the data to a Raspberry Pi.

My goal is to connect Onemeter to a Raspberry Pi which will do INSERT QUERY to the database.

At the moment, I have received information from the competition that "mReader Opto" does not work with the Iskra AM550 meter that I have installed.

If you already have this device, dear forum user, please describe your experience.
For my part, I will try to report the situation on an ongoing basis.

TvWidget: From your speech I got the impression that iNode Energy Meter has the ability to read data from the meter. After checking the data of the device, it seems to me that it is counting the blinks of the diode - thus, as you mentioned earlier, it is not possible to distinguish between the download and the sending. Please write if I am wrong about the iNode Energy Meter.

If you know any other devices that will allow me to achieve my goal - please let me know. On the wallpaper I still have the issue of buying an ordinary optical USB head, but if the meter opto is actually blocked, it will utopize money.

Regards

For me, PGE did not have a problem with what was hanging on the meter. Only the person checking the counter every 2 months asked for the first time what it was and I explained it to him and from then on it is calm. The device sucks the data beautifully, being 4-5m away from the house. The old phone is on the windowsill and it gets along. I only tried to invest in Rasberry 4 and so far I can not pair so that Rasberry sucks data from OneMeter. I am very pleased with both the technical support and the product. I only replaced the original battery from Ikea, which was sitting inside, with another Energizer. I am happy, but maybe it is a subjective matter and a matter of a meter and electricity supplier.

Hello !!!
Does anyone use this interface with a Norax 3 counter? Works together

I have an APATOR Smart Emu 3 meter installed by PGE after starting photovoltaics.
I would like to put OneMeter on the optical port of this counter. In the list of meters supported by OneMeter, APATOR Smart Emu 3 is mentioned, but with a note that it is "conditionally compatible". Maybe you have the same counter?

I'm not sure, but it seems to me that PGE is blocking everything sooner or later. I have an OTUS 3 meter myself, which is also already supported by OneMeter but blocked by the operator. There is no sign that the situation will change.

A while ago, I had a conversation about "stuck counters" with software testers at OneMeter. From the information I have learned, OneMeter is currently cooperating with the Office of Competition and Consumer Protection and several other entities that are ultimately to "hand over power" to the client. However, it is difficult to clearly indicate how long it will take.

Yesterday I had the meter replaced with a Spark AM550. OneMeter has become unusable at the moment. I am immediately sending an e-mail to ENEA Operator with an inquiry / complaint in this matter. I called the hotline, the woman did not know what I was talking about ... ;)

It begins very interestingly. Please let me know what region you are in (energetic area or what they call it there) and how your topic will continue ... I will be grateful for your feedback.

And I have Apator norax 3 in the Gdańsk region, i.e. Energa.
And the hell does not want to talk about the PV onemeter with the meter.
Of course, Energa doesn't know what's going on and sees no problem.

update
... he asked ...

First, ask the producers of popular ISKRA / APATOR / LANDIS "remote" meters if and why polling the meter on the optical port blocks its simultaneous communication and service via GSM which is used by ZE and to which it is entitled as the owner of the measuring device.

Profile measurement data are - or sooner or later - available in applications for recipients of the e-meter type.

Erratum
I did, however, but after the battles with this onemeter
first impressions that this device, locked in a metal electrical box,
It barely connects via BT to the phone even from a distance of less than a meter
that's why I had such problems, but now I'm working

next updates will be made ....

I had the counter replaced with GAMA 300 G3M 144. And now there is only the date and time of reading. The condition of the gunner is missing. It may be necessary to install from the cornfield. I have sent a request to technical support and I am waiting. It is possible to remotely block the optical connector in the meters. Jk will describe something.

ENEA wrote back to my application in CC as follows:

Sir,
Due to the fact that the matter relates directly to the Distribution System Operator (the owner of the measurement and billing systems), please send your inquiry to Enea Operator at the e-mail address kontakt(_at_)operator.enea.pl or by calling 618 504 000.
Best regards

Updating ... under the PV connection, they changed my meter to Apator Otus 3
And with this meter, the one meter did not say hell
The Energa operator ignored my questions about optical communication.
It's a pity, because it was going to be fun.
One meter returned without any problems, cash recovered efficiently.

I do not recommend the device. After replacing the battery, an error occurred and something freezes. I wrote a few e-mails and tried to get through. With no result. Apparently they have already had a hard time and have clients in .... Writing down the meter by hand is not a big deal, and seriously consider the purchase, because it's a lot of money for using crap for up to two years.

A bit late, but maybe someone still doesn't know. It works great with Norax 3 at PGE. PGE does not provide detailed online data access for solar farms and OneMeter instructed me to reprogram the meter myself. Outdoor counter approx. 6m from the house. An old phone (Samsung Galaxy J5) in the basement acts as a gateway. Of course, no card needed when there is Wifi. I have a reading every 15 minutes without any problems.

And does anyone know what Tauron's policy is in this matter? I have a photovoltaic plant and an Apator Norax 3 meter. The meter has a remote reading and I can check the consumption on the Internet, but it is not enough for energy management at home. I would like to read data directly from the meter. Is Tauron blocking the optical port on these meters?

If you have a NORAX3 counter, it is not a remote counter.
If you have a prosumer contract running, NORAX3 is hanging temporarily and will soon be replaced by a remote meter.

I went to the inbox to check and you're right, my memory has failed me. I have an Apator Otus 3 meter.

So I repeat my question:

"Safe communication by DLMS / COSEM protocol, along with authorization and encryption"

No one will give you the keys to this meter, reading through the optical port may cause a remote access lock that the EV must have.
I do not know what you need from this meter, the read profile is the same as the elicznik.

Now, each TAURON recipient can change to a REMOTE meter, even if it does not currently have one, for the time being a paid service
https://www.tauron-dystrybucja.pl/uslugi-dystarówka/zdalny-odczyt-na-wniosek

After such exchange, there is access to the e-meter and real data and there is no need to make it available to the collector (where the meter is not accessible from the outside).

I know that much, but I asked if Tauron was blocking the use of the port by the user.

=Grzegorz= wrote:

Are they needed? After all, I do not want to change the settings, but only read the state.
I am testing some old Pafal now and it reads without keys.

=Grzegorz= wrote:

Is this happening? It would be strange that reading over one communication channel blocks the other. I am an embedded developer and I write software for various devices on a daily basis. Simultaneous data exchange by up to 10 interfaces simultaneously is nothing extraordinary for today's microcontrollers. Otus is a modern counter, and if what you write about were happening, it would be poorly designed.

I have already written what I need, but maybe I will clarify: I have photovoltaics and the whole fun is not to give electricity to the grid (which Tauron cares about), but to consume it locally. But to know how much of it you need to know what the balance is. The insolation changes every now and then and the remote reading every 15 minutes, which is still delayed via the Internet, is too slow. I can consume electricity with a heat pump, which cools in summer, heats in winter, and I can control it remotely and precisely. When the sun comes out, I can heat up the DHW, and when it hides behind the clouds, reduce the heating.

In my free time I will check if and what otus spits out without the keys.
It is not easier to monitor / balance it with some own additional meter, e.g. orno?

After all, ZE is about to replace your meter with a different one, the types and models change every now and then and your concept will crash.

I will be grateful for the info.

If I don't get along with Otus, I will have to do that. But why multiply beings if you don't have to.
New meter, set up 10 months ago, so probably it will hang for at least 5 years. And ultimately, everything aims to ensure that the prosumers eat their electricity themselves, so they must have information about the balance sheet. In the future, although I do not know how far, the price of energy is to change during the day depending on the production and consumption in the system, so I expect all the more that the next meters will provide different data, and to an even greater extent.

Unfortunately, you can not read anything from otus, I checked today, only dlms and factory soft.

OTUS is supposed to be for 8 years, but there are breakdowns during which the EV can be replaced with any other currently available, in accordance with their guidelines.
You combine wisely, so I advise you to make this balance system independent of the EV

Exactly ... why multiply beings. How does ZE want to introduce dynamic tariffs with such equipment? Already now, the tariff G12 and G13 is the manual setting of hours in home machines and it should be on a signal from the meter.
