(Guest writer) Echelon/NES Smart Meter – FHEM integration in Austria

FHEM Home Control

Back in June 2022 Engelbert Horvat reached out to us to discuss a MEP solution for his Echelon/NES Smart Meter. Engelbert lives in Austria, so unfortunately our module is not a good solution for him. Although the MEP electrical connections and protocol is standardized in these meters, the MEP “drawer” our modules are designed for is a Danish thing – and has even been abandoned in the NES Smart Meter Generation 4 on the Danish market. Note: It would be possible to use our module, but it needs to be connected by wires and one should probably also create an enclosure for it.

Luckily Engelbert is also a fellow tinkerer, so although we inspired him, he developed his own hard- and software solution. To get people to do this has always been our mail goal and we asked him to tell his story as inspiration for others:

Hi, my name is Engelbert and live in Austria in the city of Amstetten which has its own power supply company (the “Stadwerke Amstetten”). They have around 12000 Echelon/NES Smart Meters installed. I wanted to interface with my smart meter and send informations via MQTT to a home automation system (FHEM in my case).

First contact and tests in June 2022:
I was asking “Stadwerke Amstetten” how to interface with their smart meters and eventually was finding the right person who had very good knowledge and enough motivation. To my surprise he gave me a spare NES smart meter just for testing, “I can fool around with this a bit for the next few month or so” he told. Also I got a xml file with the basic Encyption key (MBK) for this smart meter. So no problem with obtaining a MBK at all….my thanks are going out to Stadwerke Amstetten. But I was told that it is not so easy to get out data, and also that I was first one who was asking for this in Amstetten.

Finding the Echelon/NES smart meter informations on the site was just great and I did hope to be able to go on with this.

Gert was providing me with the current (at the time prelim) ESP32 MEP interface software, and some installation hints as well. (They where mostly in Danish language, but Google does a great job in translating…).

So I wanted to get some readings from the smart meter quickly….

Hardware wise I had a ESP32 Module (ESP32 Dev. Kit) which is supplied and programmed via a micro USB port. Also I found a old MAX232 (exactly a MAX232ECPE for 5 Volt !) and the capacitors in my electronics storage. Because MAX232E is a 5V but ESP32 is a 3.3V device level shifting for the RX data out of the MAX232 must be done. I did just a simple voltage dividor with 2 resistors (1k / 1.8k). For the TX signal to MAX232 I was hoping that ESP32 delivers enough voltage for the 5V logic of the MAX232. So I came up with a simple schematic – basically a stripped down version of the NES-MEP from, including now a ESP32 Module. Please visit and look for the file NES-MEP-5Volt.pdf.

I have checked also some voltages and power consumptions. MAX232 provides 2 voltage charge pumps and their output can be measured on pins 2 (VS+) and 6 (VS-) . Note: using 100nF caps for a MAX232 is a bit out of spec. Caps should be 1µ for MAX232E but 0,1µ for MAX232A or MAX3232, but it was working well and I could easily exchange the MAX232 with a low volt MAX3232 later. At a power supply of 5V the MAX232E gave 8.2V on VS+ and -7.3V on VS- during operation.

I have also tested on 3.3V level with a MAX3232 in combination with a LM2596S based step down converter. At a power supply of 3.5V the MAX3232 gave 5.8V on VS+ and -5.5V on VS- . All supplied by the NES Smart meter 26V output which used then app. 18mA on average, with some short peaks due to Wifi communication up to 30-40mA (and this may lead to problems – see notes at the end.)

Software wise was also no big deal with a little help from Gert.

Please note that the MEP basic key (MBK) comes in different forms:
a) ASCII which should be 20 characters long similar to this: a7941d85bce8a8fa2ab7 .
b) HEX representation of the ASCII format which would be similar to: 6137393431643835626365386138666132616237 so this is 40 char long where ASCII is shown in hex (ASCII a = 61(hex))
c) Decimal representation of the ASCII format which is like hex, but each ASCII is shown in a decimal.

Final (…kind of) PCB design Aug 2022:
I have designed now a PCB which holds the MAX3232, a ESP32 Module and a DC/DC converter to 3.3V.

Another issue is how to physically connect to the MEP port in a home environment. At my place the MEP port terminals are covered by the lower plastic cover which is sealed off by the power company in my case – it is not allowed to cut the seals !!. As a first try “Stadwerke Amstetten” would be ok to take the seals off so I can put the hardware inside the NES meter covers. But I did not like that, I want the NES-MEP-ESP32 to be easily accessible. So I have convinced them to to another solution.

Which is that the owner of the smart meters (the power company) will open the sealed off cover and install a little connector to the MEP port terminals which are then routed outside using a 6-wire flat ribbon cable. The flat ribbon cable fits through the gap of the plastic cover on the back of the meter and the hardware can be placed outside the meter. The smart meters have to be excanged on a regular basis (3 years ? For calibration checking) so this must also be taken into account.

Github Repo Nov. 2022:
I wanted that ESP32 is sending NES meters data via MQTT to my home automation system. So I stumbled over a nice project on GitHub called AMS2MQTT Bridge ( and modified this to read data via MEP port from the NES smart meter. You can find this on my GitHub at You will find there also detailed info about the used hardware.

1) I have found that NES meter power supply is quite limited and on some meters just too less power is provided to drive ESP32….which is no big deal since I am using ESP32 Modules anyway which have an USB port for programming and power supply. So for some (I had only problems with NES Smart Meters Type 83332-3I)

2) My software uses the hex format of the MBK Key and not the ASCII representation used in Gerts NES-MEP software. The “hex” MBK is 40 char long as each ASCII is represented by a 2 digit hex number.

Kind Regards,
Engelbert Horvat

[Limited offer] Echelon/NES Smart Meters – MEP interfaces modules and kits

Limited Time Offer

This is a follow up on our previous Echelon/NES Smart Meter post.

We have released all our Hard- and software on GitHub here:, so your cheapest way of getting started if you have soldering skills is to order a PCB and components – and start building your own modules.

We hope that someone will pick up the task of producing/selling kits and assembled modules, but we have decided to offer some ourselves for a limited time to get more people involved.
Note: The price is set so others will have a chance of under-bidding us, that is on purpose.

If you buy one of our modules we expect you to participate in the project in some way. It could be as simple as write your story/experience about the project (as a guest writer on or on the OSGP Alliance GitHub site), or if you have the skills you can help develop/improve the hard- and software.

We have two options:

  1. The MEP module as a kit, all components included. The ESP32 is a 16MB version.
    You are required to have the tools and skills, to assemble the PCB, adjust the buck converter and program the ESP32.
    The PCB/components are classic through-hole-technology (THT) so you don’t need to have good SMD skills.
    But note that the ESP32 is a separate PCB with castellated holes (that is kind of like SMD).
    As the module is NOT assembled, we cannot test it or install the software. You’ll have to do that yourself.
    Price: 300 DKK including freight in Denmark (payment due before shipment (bank transfer, PayPal or Mobile Pay).
  2. An assembled MEP module. The ESP32 is a 16MB version.
    The Module is flashed and should boot into Access Point mode when mounted in the Smart Meter. You should then be able to go to the homepage of the module and configure it to use your WIFI. Here you will also be able to enter the MBK key you got from your Power Company.
    PCB and components are mostly classic through-hole-technology (THT), but the ESP32 is a board with castellated holes.
    We might also choose to provide SMD versions at the same price depending on component availability. You will be asked if SMD is OK with you before shipping.
    Before shipment we will make sure the module boots correctly in our Smart Meter, but we won’t perform a long/extensive test of the module.
    Price: 500 DKK including freight in Denmark (payment due before shipment (bank transfer, PayPal or Mobile Pay).

This is a prototype project without ANY form of warranty. Any use of this module is your risk and costs!
We cannot gurantee delivery times as we purchase most components from China to keep the cost low. Delivery times may vary from 0 to 2 months or in special cases even longer.

AS we currently have no experience with the IR solution, we will NOT be providing any hard- or software for that at this point.

Please send an e-mail to and, stating if you want a kit or an assembled module. Also state your shipment address.

Please let us know if you have any questions.

[Breaking News] Echelon/NES Smart Meters – Documentation for MEP and Optical interfaces have been released on GitHub!

Breaking News!

It is with great pleasure we finally can announce the release of the following official OSGP Alliance documentation for OSGP Smart Meters (i.e. Echelon/NES Smart Meters):

  • The Multipurpose Expansion Port (MEP) interface and protocol
  • Optical interface and protocol

You will find the PDF files in the Documentation repository at GitHub using this link:

Thank you for your patience, we know this have been under way for almost two years.

Now, go ahead, please start Tinkering now! 🙂

Note: The hard- and software we’ve been tinkering with is not finished (probably will never be finished as it is a tinkering project 🙂 ), but we’ll get it released ASAP so others can get inspired or join as they wish.

Echelon/NES Smart Meters – dabbling the hardware v1.10 and v2.00

PCB v1.10 and 2.00

Our software fix for the (fake?) MAX3232 hardware issue seems to solve the issue completely.

It is still a rough implementation in the software (using delays), so we’ll have to improve on that later on… It is probably not that big of an issue – because when a MAX3232 starts to behave, it seems it continue that way for a long time…

Next step is then off cause a new hardware prototype PCB, but why not add a few things like:

  • R3 & R4: a few resistors so one can chose if our software fix for the (fake?) MAX3232s should be used (0 ohm R4 installed) or not (0 ohm R3 installed). You might even chose to use a higher resistor value if that works for you. You should only install either R3 or R4 – NOT BOTH!
    Note: If you don’t have 0 ohms resistors, just bridge the pins.
  • R5, R6 & R7: a few resistors on the MAX3232 pins so you have the option to see if your MAX3232 works better if you add some higher resistor values to the pins. If not, you can just install 0 ohm resisters or bridge the pins…
  • …and let us move to SMD now we are at it (actually we also have a PCB version 1.10 which is classic THT (Through Hole Technology) as the earlier versions.

The schematics now looks like this:

Hardware version 1.10 and 2.00 schematics

A 3D rendering of the PCB (for some reason without a 3D MAX3232) looks like this:

ESP32 MEP PCB v2.00 (SMD) - front
ESP32 MEP PCB v2.00 (SMD) – front
ESP32 MEP PCB v2.00 (SMD) - back
ESP32 MEP PCB v2.00 (SMD) – back

The idea around putting C1 – C5 on the back is to shorten the traces from the MAX3232 (supposedly that is also better according to it’s datasheet… But what do we know – we are software guys 🙂 )

We’ve just received the PCBs from JLC PCB (no, they are not a sponsor – we pay for this), but have not had time to populate nor test them yet…

You can see the received PCBs in the feature image of this blog entry.

Stay tuned for more news regarding this project – only on…

Note: We are still waiting for NES to release the MEP protocol specifications…

Echelon/NES Smart Meters – the software solution to a hardware issue

Well, we warned you that software guys like us tend to come up with software solutions – even for hardware problems.

As expected, no electronic engineers reached out to us with a solution for our (probably fake) MAX3232 issues, so we had to come up with a solution ourselves…

That is off cause ok – and with the help of a cut PCB trace:

Hardware v1.03 - cut trace to solve MAX3232 issues
Hardware v1.03 – cut trace to solve MAX3232 issues

… and a bodge wire:

Hardware v1.03 - bodge wire to solve MAX3232 issues
Hardware v1.03 – bodge wire to solve MAX3232 issues

… it seems we can persuade the MAX3232’s to play along.

This is off cause a temporary solution to test this fix – we need a new PCB prototype version if this works.

Note: You will find others struggling with similar MAX232/3232 issues on the Internet. Some are able to solve it with larger decoupling capacitors and some with resisters on the power pin – but that did not work for us.

Our implementation is simply adding control of the power to the MAX3232 through software. When it mis-behaves we punish it by turning it off for a while. Then back on until it behaves…

Note: the max current a ESP32 digital pin can supply seems to be around 40mA and the max consumption of a MAX3232 is around 1mA. So we should be safe doing this “hack”…

If you are an electronic engineer you are probably finding this solution fun – but it seems to be working :-).

While we are still waiting for the MEP Protocol specification to be released (and our NDA to be lifted), we’ll try to keep your entertained with more blog entries.

Stay tuned to…

(Guest writer) Echelon/NES Smart Meters – Home Assistant integration

Home Assistant Logo

This is a bonus entry on our blog in the Echelon/NES Smart Meters series. We have limited time and are devoting the sparse time we have on the hard- and software needed for the ESP32-MEP module. We are aware that other systems should be able to integrate to the solution, but we currently have no experience with stuff like “Home Assistant” etc.

This project was never supposed to be a private project anyway. As you know if you’ve been following this blog, the end goal is to get the specification released. As soon as that happen we’ll release our hard- and software as well, and others can choose to join us in improving it, start their own project from the specs or even branch our project and move on from there.

We would love to see this grow in all sorts of directions…

Luckily others have more knowledge in integrating with “Home Assistant” and one of the more persistent persuaders must have been Jan Nielsen. He got a private access to a webservice on Gert’s ESP32-MEP module to see if he was able to integrate to it…

…and best of all: when asked he immediately wrote this blog entry about it – sharing his findings. The rest of this blog post is written by Jan Nielsen, so send all praises and credits to him:

Jan Nielsen
Educated as Data Technician (Data Mekaniker) from EUC Syd in Sønderborg in 1997.

I have worked some years as a full-time developer; then switched over to system administration.
But still with an interest in automation when there is a need, and occasionally some hobby projects.

Hi there, my name is Jan. Like I assume many of the people reading this, I have been following this blog for some time. I found it back in August 2021, after first seeing Gerts post at

At the time I had recently discovered the Home Assistant project. My interest was to get a chance to play around with Zigbee – more than Philips Hue allowed for.
Shortly after the August update was released. The big news there was an energy dashboard, and a few more things related to it like long-term statistics etc. In this context energy meant electricity consumption and production (solar).
Without digital access to the overall household consumption this was not really useful.
You can get Zigbee, Wifi, Bluetooth og probably Z-wave plugs that can measure power consumption, but it is only a portion of the consumption.

Some solutions for reading total electricity consumption:

  • A guy named Jonas Pedersen had made a HA integration that pulls in data from an API at This is working, but data is two days delayed, and for that reason not suitable for the energy dashboard.
  • The HA release mentioned two solutions that were already supported. A solution for Dutch meters that apparently has a serial port with an open and documented protocol, and another one for counting the number of blinks from a LED on the meter. Well yes, that second one would probably work with an Echelon meter also, but still not quite delivering what I hoped for. For example it does not get the total consumption value seen in the display, if for some reason counting pulses is impaired consumption during that time is simply missed. Additionally I assume it will not give current power usage in Watt, or it must be derived from time between two pulses, which can be quite lengthy when consumption is low. If I have to fiddle with electronics, it has to be a solution I believe in, and that I find at least somewhat smart.
    Similarly ready-made devices like this are available for purchase. But it seems fairly expensive, when in doubt how well it can actually do it.
  • Lastly, Develco seems to have developed a really interesting module for the MEP port. But as the guys discovered it cannot be purchased anywhere, at least not only a single or a few pieces.

    So, when I found this blog here it was the most promising solution. Thus, I have been waiting and regularly checked for news and progress…

At the end of January when I saw Gert mentioning some web service, my interest was raised further.
In the autumn I made a HA integration for Min Volkswagen. It simply pulled in data from a API. I first learned about this API from Esben on tech at Youtube. However, his approach was to use Node-RED. This I found a bit cumbersome, especially with the location tracker that had to be configured in multiple places. So, I took the challenge and tried to write an integration for HA, which would be easy to use and configure.
The API was really easy to use as Esben had shown how to do it. The HA part was more challenging and had quite some learning curve, but by studying other examples, documentation and at times HA source code I eventually got it working, including a UI dialog for the initial configuration.
Back to the MEP webservice… if the guys had made a webservice I would rather easily be able to pull this data in, similarly to how I had already done with Min Volkswagen. So, I reached out to Gert offering to be a tester 😉, but also to implement a HA integration that could consume the webservice. Due to the NDA Gert was, understandably, not that keen on the idea, but he did offer remote access to a webservice. As for the development process this would be perfectly ok, and overall bring us faster to my goal of getting this data into HA. So, I accepted Gerts offer.

So, I cloned my previous HA integration and started to adjust the API reader code. As the webservice is very simple this was mostly a matter of removing authentication, and code to handle multiple cars/devices from the same web service instance.
Simplified, the basic steps to read it looks somewhat like this:

async with aiohttp.ClientSession() as session:
async with session.get(req_url, headers = headers) as response:
temp = await response.json()
if temp is not None:
_LOGGER.debug(f"Got meter data: {json.dumps(temp)}")
self._data = temp

except aiohttp.ClientError as client_error:

And next to adjust each value, named a sensor in HA, that I wanted to make available in HA:

sensors = []
sensors.append(MeterEntity(config_entry.entry_id, config["name"], "energy consumption", "", False, True, _meterclient))
sensors.append(MeterEntity(config_entry.entry_id, config["name"], "energy returned", "", True, False, _meterclient))
sensors.append(MeterEntity(config_entry.entry_id, config["name"], "voltage", "L1", False, False, _meterclient))
sensors.append(MeterEntity(config_entry.entry_id, config["name"], "voltage", "L2", False, False, _meterclient))
sensors.append(MeterEntity(config_entry.entry_id, config["name"], "voltage", "L3", False, False, _meterclient))
async_add_entities(sensors, update_before_add=True)

class MeterEntity(Entity):
"""Representation of a Sensor."""

def __init__(self, config_entry_id, meterName, itemName, phase, returned, entity_registry_enabled_default, meterclient):
"""Initialize the sensor."""
if self._itemName == "energy consumption":
self._icon = "mdi:home-import-outline"
self._device_class = DEVICE_CLASS_ENERGY
self._dict["state_class"] = "total_increasing"
elif ...

async def async_update(self):
"""Fetch new state data for the sensor.
This is the only method that should fetch new data for Home Assistant.

# Measurement
if self._itemName == "energy consumption":
energy = await self._meterclient._get_value(["Fwd_Act_Wh"])
if (energy is not None):
self._state = int(energy) / 1000

Within a day or so data started to roll in.

At first the webservice had the accumulated consumption, returned to the grid as well as voltage and current for each phase. As I find power more relevant, I had to calculate this from voltage and current. Since then the webservice has been extended with power readings and more.

When it all seemed to run smoothly, one day it turned out to have registered a humongous consumption.

Unfortunately, I did not make a screenshot of it before correcting the data, but here is what it normally should look like:

Home Assistant - Echelon energy consumption
Home Assistant – Echelon energy consumption

As it is the kWh counter it should be forever increasing. Little consumption will be slowly increasing, higher consumption will increase steeper.
When the problem appeared, it rose all of a sudden thousands of kWhs, and shortly after fell back to normal.

Due to the way I had defined the sensor in HA, this was a bigger issue than just that short glitch.
For it to be usable with the Energy dashboard it needs to have statistics collected each hour, and this requires a ‘state_class’ defined. For this kind of data it can be ‘total’ or ‘total_increasing’. To support meter reset the ‘total’ type requires a date specified where the meter was reset. Instead the ‘total_increasing’ type, which I had chosen, will see a decrease as a reset.
As the Energy dashboard works with the deltas, not only did the increase add thousands to the depicted consumption, when returning to normal it also added 117.000 kWhs because it assumed it was reset to zero and then consumed the reported value…

Gert had also noticed this at times, and had also mentioned it to me earlier. But in my rush to get something to show up I had also totally forgotten about it.
Rather than having to specify a reset date or risking negative consumption, I decided to continue with ‘total_increasing’. However, I did implement a limitation that would sanitize the kWh reading. If it increased more than 1000 Wh or decreased from the latest reading, it would discard the new value for up to an hour until finally accepting the new value if not returned to a more realistic value. It is only done in memory though, so not totally fail proof if HA is restarted during an issue, but it minimizes the risk.
A few days later Gert reported the issue had been found and firmware updated.

At the same time there was more info added to the webservice.
In a previous blog, it was shown that it could return info about itself like manufacturer, model and version. Although secondary, I find it nice and convincingly to have that reported as well.
Not only did the added info have metadata about the meter, it also turned out that similar data about the MEP module had been added.
In HA a device only has a predefined set of properties. So, how to depict both sets of device info?
Although not originally planned, it turned out simple enough, just make it appear as two devices. The meter itself and the MEP module:

Home Assistant - Echelon
Home Assistant – Echelon
Home Assistant - Echelon MEP
Home Assistant – Echelon MEP

To do this, it requires at least one sensor on the MEP module. This is because it is the sensor that returns info about the device it is part of.
In this case I invented two binary_sensors that tell something about the status. One if the last http request succeeded, and two if the data returned doesn’t look as expected.
The “Connected via” relationship was new to me, and also something I wanted to try out… 😁 But it just worked, so no challenge in that.

As Gert and Graves had taken care of the difficult part, the most challenging part of this integration turned out to be the Configuration button, or as it is known internally the OptionsFlow.

Home Assistant - Edit connection settings
Home Assistant – Edit connection settings

This I had not made with Min Volkswagen. The UI itself was not much different than the initial configuration, but I wanted it to be able to update the url to the MEP module and to change the scan interval (how frequently it polls the webservice).
The challenge with the url was that configuration and options are stored under different keys. And I didn’t like the idea of writing to both keys, and then making sure to read the right one if both were present.
Although I thought it would be a normal use case, I had to find a way to do it in a community thread where other developers had the same need.

Even worse when I wanted to make the scan interval configurable.
Gert had expressed concerns about the ESP32 being overloaded with requests, so I decided that polling it every 5 minutes would be sufficient for many use cases. In particular if the primary interest is the total kWh reading.
However, if you are interested in checking the power usage right now and want to see the difference when some device is on or off you need much more frequent updates.
Although you can buy plugs with the ability to report the consumption for a specific appliance, let’s also enable use cases that require readings from the meter almost as frequently as you might like for whatever purpose. When you have it in your own home and only polled by you, it is of much less risk of being overloaded than the module being exposed online right now.
HA has a really simple way for an integration to set a scan interval. It is a hardcoded value that I have not found a way to change dynamically. For integrations not using ConfigFlow and OptionsFlow it can be set in the configuration file, but making this apply requires a restart…
After studying other examples, I ended up disabling the built in triggering mechanism. Instead setting up a timer, that would fire an event to the sensors when it is time to update.
A change in the OptionsFlow dialog will reload the integration anyway, so although the timer is set up at load time it will update the timer interval when changed.

Besides the expected benefits, being able to reload the integration also turned out to have other advantages. Now it can unload the integration without restarting HA core, or enable and disable sensors without restarting. Just a much more convincing experience.

The integration is made publicly available for anyone to use. But to be usable in any way you will also need the hardware and not least the firmware, which currently awaits release from the NDA. So, continue to keep an eye on the blog for updates.
The integration can be found here:
You will also see more screenshots in the README file.
Be aware that it does not contain any information about the MEP protocol. It just consumes the webservice provided by the ESP32 firmware, that is where the secret source is.

For ease of use and installation, I will try to get it into the HACS community listing of custom integrations.
The challenge will be if we can get a logo accepted, which is required. I already experienced once it is not so simple if you do not own the trademark rights. So, now we try to put it under the name and logo.
Until included in HACS, you can add the url above as a repository to HACS yourself (as described in the installation instructions) and it will work just like it was. Only thing missing is the logo in the integrations overview.

(Long time no see) Echelon/NES Smart Meters – Draft document received!!

MEP Client Developer's Guide, cover page

Sorry it’s been some time since the last update – but please read the comment sections on the older entries – this project is still kicking, and we try to find time to at least answer the comments.

Let us admit – we were worried… It seems NES went into some kind of radio silence mode during end of 2021 and start of 2022 – but finally in mid January we manage to get a hold on them.

They apologized that the MEP-protocol specifications was delayed – the team simply had to work on other more urgent projects… We fully understand that stuff can get delayed when you are “hit by reality”. After all – this release is for the community, not something a company can pay their bills with :-). And Graves and Gert also have to attend their day job to get bills paid. This is – after all – only a spare time project.

Anyway – NES assured us that it would now get prioritized a bit higher again and hopefully soon be finished.

BUT EVEN BETTER – earlier this week, Gert received a draft PDF with the “release version” of the “MEP Client Developer’s Guide”. This shows us that NES are still actively working on this. Due to the NDA we cannot share much, but you will find an image of the cover page as the featured image of this entry.

It is clear that this is still supposed to be released through OSGP Alliance. Just like promised previously by NES.

A quick glance through through the PDF shows that the document has been revised, even improved a lot. And – more important – it seems that most of the protocol is still in there… So this is REALLY good news. We’ve promised to proof read it a bit and give feedback. But we are really looking forward to be able to link to the release when it is ready.

Sorry for this short – but at least positive – update.

We’ll get back to you with progress on software and hardware soon. And hopefully also soon with some news about the release of the documentation.
