Re: [SPAM] Re: [SPAM] Re: Connecting weight scales to Odoo
Thanks a lot Hugues, This is very enlightening.Kind regards,HoussineLe mar. 3 févr. 2026 à 18:37, hugues de keyzer <notifications@odoo-community.org> a écrit :hi houssine,
first, i think that what tom is referring to are independent self-service weighing scales (not related to odoo) that print barcode labels encoding the weight or price. scanning these works indeed in the pos without any special add-on.
the code we wrote allows to use odoo to do the equivalent of these independent self-service weighing scales. this has the main advantage of not needing to update the products database of the scale (either manually, with usb flashdrives or complex ftp setups), as the code has direct access to the pos products. it also allows to print tare labels (to use with the
pos_taremodule), what these independent scales can maybe not do. another advantage is that it can be cheaper than these specialized independent scales, but it depends on the hardware used.for this to work, you will need:
- a computer that can run gnu/linux and a recent browser and the pos interface (could be a raspberry pi)
- a touchscreen
- a weighing scale that can be connected to the computer
- a label printer that understands zpl
- (optionally) a barcode scanner to scan tare barcodes
we usually go for ancient (second-hand) pcs with ubuntu, a robust touchscreen, a mettler-toledo ariva s and a zebra printer.
the scale could be replaced by cheaper models (epelsa or baxtran for example), as long as there is some software that can talk to them and provide the same http interface (for weighing) as the iotbox, like pywebdriver or the new odoo-driver).
kind regards,
hugues

Hi Hugues,
One more question.
I've maybe missed it in the PR but I can't find a list of supported scales. Is there such a list somewhere or this is the standard scales supported by Odoo?
Any set of hardware and OS you can suggest ? For my remembering we were running the Touchscreen unders ubuntu to run the posboxless on it. This is still needed ?

Re: Weighing scales
Hi all,
thanks Frederik for looping me in – happy to share what I know.
MY LAST OFFICIAL INFORMATION FROM ODOO:
About a year ago (maybe a bit less), I was told by Odoo that they were in the certification process for scales in Paris. Since then: radio silence. Nothing public, no announcement, no certificate number, nothing I could show to a customer or an authority. So as far as I'm concerned, the certification status is still "pending" at best.
WHAT THE GERMAN AUTHORITIES TOLD US:
We had direct conversations with the Eichamt (weights and measures authority) here in Germany, and they were very clear:
The ENTIRE SYSTEM needs to be certified and calibrated together:
- The scale itself
- The IoT box / communication layer
- The POS hardware
- The POS software
All of it. As one integrated, sealed system.
Now, if you know Odoo... that's almost impossible to achieve. Odoo's strength is flexibility – you can configure almost anything, install community modules, customize freely. And if you're on Odoo.sh or SaaS, you're getting continuous updates. That's the exact opposite of what calibration authorities want: a frozen, audited, unchangeable system.
REGARDING JAN'S THEORY (FISKALY TSE = SCALE OK?):
I would be EXTREMELY INTERESTED to hear more about what Jan found out, because frankly, I don't see how this could be correct.
The fiskaly TSE certification and scale/weighing certification are:
1. Two completely different legal frameworks – TSE is about fiscal compliance (GoBD, KassenSichV), weighing is about legal metrology (MessEG, MessEV, NAWI/MID directive)
2. Two completely different authorities – Finanzamt (tax office) vs. Eichamt (weights and measures office)
3. Two completely different purposes – One ensures tax transparency, the other ensures consumers aren't cheated on weight-based pricing
I don't see any legal or logical connection where certifying the cash register for tax purposes would automatically certify the weighing system for trade use. These authorities don't even talk to each other.
MY SUSPICION ABOUT THE DOCUMENTATION CHANGE:
Looking at the diff between Odoo 17.0 and 18.0 docs – yes, they removed the explicit warning about France, Germany, and Switzerland. But removing a warning from documentation is not the same as obtaining certification. I suspect this was a commercial/marketing decision rather than a reflection of any legal change.
If Odoo actually got certified somewhere, I would expect:
- A proper announcement
- A certificate number we can reference
- Updated documentation that says "certified in X countries" rather than just removing the negative statement
MY POSITION FOR CUSTOMERS:
Until I see an official certificate, I continue to advise customers in Germany to use the workaround: a standalone certified scale that prints labels with barcodes, which are then scanned into Odoo POS. Not elegant, but legally safe.
LOOKING FORWARD:
That said, I do think this whole situation is outdated for 2026. The current calibration laws were written for a world of standalone, unchanging devices – not cloud-connected, continuously updated software systems. I hope regulators will modernize this eventually, but that's a slow process.
Jan – if you have any concrete documentation or official statement that supports the "fiskaly = scale OK" theory, I'd genuinely love to see it. Maybe I'm missing something, and I'm always happy to be proven wrong if it means we can finally use integrated scales legally.
P.S.: Frederik, thanks for the hint about the Hamburg OCA Sprint – Jan-Marten, feel free to send me the details!

well the latest i heard on this was from fellow Odooer Laurence Labusch (and his company Labiso GmbH). He has spent considerable time to narrow down that issue with the authorities and afaik it is still not allowed to use an electronic wheiging scale even if the POS itself is working according to the national standard which in Germany is implemented using fiskaly TSE unless the whole POS is certified with the weighing scale but maybe Laurence (which i am putting on copy can answer himself).

P.S.: Jan-Marten maybe you can make Laurence aware of the Hamburg OCA Sprint ;-)

My latest information (more a guess/feeling) from Odoo customer service (and some online research) on this was that if the POS is certified (like e.g. Odoo POS via fiscaly is in Germany), then the scale itself does not need to have an additional certification, and that this may explain why Odoo removed the below notice from its later documentation from v18 on
"Odoo is not certified in several countries, including France, Germany, and Switzerland. If you reside in one of these countries, you can still use a scale but without integration into your Odoo database. Alternatively, you can acquire a non-integrated certified scale that prints certified labels, which can then be scanned into your Odoo database."
Anyone has more clarity on this scale certification part in Germany or other EU countries?

Re: Weighing scales
there are indeed different regulations for the pos from country to country. one of these is only related to connecting a weighing scale to a pos and applies to all member states of the european union (afaik).
odoo has recently been certified by the lne (a french certification instance) regarding this. the certificate (in french) can be found here (search for “odoo” as certificate holder or “40724” as certificate number).
this certificate applies to odoo 18 and later. unfortunately, to comply, you will need to use the
l10n_eu_iot_scale_certmodule, which is part of odoo enterprise.afaik, this certificate is valid for all member states of the european union.
it would be great if we could have a similar certificate for the oca. the problem is that getting one requires a lot of work (painful documents to produce) and is expensive (at least €10k as fees), and only valid for parts of code that cannot be changed later (checksums are checked) without requiring a (paying) revision. there are some discussions in progress (at coop it easy) around this with a current certificate owner that could possibly be revised, but nothing decided yet.
kind regards,
hugues

So just to be clear , even if I have a certified weighing scale, odoo itself isn't certified enough as POS in european setting?
AFAIK, there is not an european cert for PoS, at least for weighing, in some regions of Spain we must certificate our accounting software in local tax authority but in others regions not...
When a client of ours (a supermarket) has had an inspection by the consumer authority, they have checked with a known weight the scale and the final result in the PoS, they validate the whole set is measuring fine in display and final ticket. They asked for the certificates of the scales, but they didn't say anything about the software.
I think we are mixing two different legal issues in PoS:
1. Accounting, each region has its own rules.
2. Consumers, each scale must be certificated, revised properly, measuring fine and must communicate reliably with PoS software.

My understanding was that this was actually a standard Odoo feature and that no extra module is needed, but Hugues would know better, i didnt actually implement this for anyone myself

Re: W0223 (abstract-method) warning in pylint-odooHi
Hi, I'm not quite sure if this one should be ignored for Odoo or not, but for examples of Pylint configurations you can look at the OCA CI template: https://github.com/OCA/oca-addons-repo-template/blob/master/version-specific/mqt-compat/.pylintrc-mandatory.jinja Or how it works out in actual repositories: https://github.com/OCA/server-tools/blob/18.0/.pylintrc-mandatory -Tom On 1/31/26 9:42 AM, Serhii Miroshnychenko wrote: > > Hello, everyone. > > When I check any Odoo module using pylint-odoo, I always get the > warning “W0223: Method ‘onchange’ is abstract in class ‘BaseModel’ but > is not overridden in child class ‘...’ (abstract-method)” for any class. > > Please advise if this is a false warning.

W0223 (abstract-method) warning in pylint-odoo
Hello, everyone.
When I check any Odoo module using pylint-odoo, I always get the warning “W0223: Method ‘onchange’ is abstract in class ‘BaseModel’ but is not overridden in child class ‘...’ (abstract-method)” for any class.
Please advise if this is a false warning. If not, what is the reason for it?
Also, please tell me if there are any recommended .pylintrc settings for high-quality Odoo development.
Thank you!

Propose of a module to handle stock evaluation
Hi all,there is a wip proposal from a member of the Italian community for a module to manage the stock evaluation with the standard methods (FIFO/LIFO continuous or periodic, AVG, standard) here:https://github.com/OCA/stock-logistics-reporting/pull/442 which supports many useful functions, like making evaluations with different methods, exporting deeply, show details of the evaluation by single records, etc.We were wondering if there are any interests from other countries in this module, if not, we'll move this PR on our localization for a better and faster integration.Best regards,Sergio Corato

Re: OCA will be at FOSDEM (31Jan/1st Feb)--> help us on the booth
Hello everyone,
This is a reminder in case you come to FOSDEM this weekend, come and see us at the OCA booth (F-02)!
And if you can join and spare 1 or 2 hours with us, please add your name here:
https://docs.google.com/spreadsheets/d/1xmOLcXD1uG3TvIXDs4X7wx9_I9-nmR5kCP5uTG6uVVo/edit?gid=0#gid=0
Have a nice end of week,
Virginie

Hello dear OCA members and contributors,
I hope 2026 is starting good for you, your business and your families!
I am happy to share that the OCA will be officially represented for the first time during the biggest open source event in the world, the well known FOSDEM. If you don't know about it, you'll find more about it here : https://fosdem.org/2026/
It's in Brussels (Belgium), on Saturday 31st January and Sunday 1st February.
It's a great experience, even if you are not a developer. I've been attending this event for many years and it's something to see once in your life: the city of Brussels become full of geeks and open source enthusiasts. The event takes place in the university (ULB) in many different rooms in 6 different buildings. It's also a good way to take your 10.000 steps a day ;) I particularly appreaciate the Community Dev Room, as well as the "Funding the FOSS ecosystem" Dev Room. There is a Python Dev Room, topics about Securyity, Performance, Testing... so many interesting things to learn!
For the first time, the OCA will be at FOSDEM with a booth (a stand), located in " F-02" together with Dolibarr ERP CRM.
I am looking for volunteers to help on the booth. That means: you need to be there for one or more shifts of 2h and talk to people who ask questions about Odoo, the OCA and open source ERP in general. We are already a small bunch of people (I can name hugues from Coop IT Easy, Sébastien Beau and Benoit Guillot from Akretion France, and even a developer working at Odoo, Stéphane Bidoul might join for a bit on Sunday.. and you?!)
Even if you are new in the community, your perspective will be good to share at the booth. No need to be an old-timer to come and help. It's also a nice way to meet other people of the community in real life.
Julie helped me set up this shared document so that you can indicate when you are happy to join the booth:
https://docs.google.com/spreadsheets/d/1xmOLcXD1uG3TvIXDs4X7wx9_I9-nmR5kCP5uTG6uVVo/edit?gid=0#gid=0
I'll get in touch with the volunteers a bit before the event starts.
Have a nice week, everyone!

Re: Reciprocity in PR opening vs reviews; banning contributors
On Mon, Jan 26, 2026 at 11:42 PM Graeme Gellatly <notifications@odoo-community.org> wrote:This might sound like a crazy way to handle, but how about solving by setting a PR limit per repo. So a PSC can set a policy of say, at any given time, only 10 open PR's are allowed, and no PR can be older than say 4 months. Once limit is hit, no new PR can be accepted until limits resolved.This is basically kanban? I'd be willing to participate in a trial of this on any of the repositories that I follow.
