• Re: Weighing scales

  Hi!

  
  

  Check l10n_eu_iot_scale_cert.

  I only saw the internal message below on 25.09.2025, claiming that this was valid in all Europe.
  

  
  

  Dear colleagues,

  I’m pleased to share that we have received LNE certification for the use of scales in the Point of Sale. This certification applies to version 18.0 across all EU countries. While mandated by an EU directive, this was particularly important for countries such as France, Switzerland, and Germany.

  Our R&D team is already working on certifying version 19.0 as soon as possible.

  Please note:

  • The module is not auto-installed; clients will need to install it themselves. See screenshot below.

  • This module certifies the Point of Sale with the LNE (Laboratoire national de métrologie et d’essais), which is a legal requirement in certain EU countries. It enforces specific settings and generates a checksum to ensure the code has not been tampered with.

  • Note that we are currently integrated only with Mettler Toledo scales using the 8217 communication protocol. To enable integration (so the weight is automatically recorded in Odoo), an IoT is required. We strongly recommend using the physical IoT rather than the virtual one, as the physical IoT includes the necessary drivers and interfaces. The virtual IoT relies on drivers installed on the client’s Windows PC.
    

  
  

  Avec mes plus sincères salutations,

  Hi all
  
  thanks @Laurence for this very helpful clarity that seems to settle the uncertainty for now at least for the German case, given you spoke directly with the German measuring authorities/Eichamt.
  
  As I had written, my theory was" more a guess/feeling" from the bits and pieces of information that my last research on this had yielded, including some (shaky) statements of Odoo customer support like these
  
  "I've looked into this and found that the certification is twofold: one being the software (Odoo), and the other being the hardware (scale manufacturer). Odoo is certified to weigh items, so one half is covered, but the hardware itself must also be covered."
  
  As for for your surprise on any "legal or logical connection" between TSE and scale, this was a misunderstanding. I did not mean to suggest: From TSE certifications follows scale certification. I meant to suggest: If you use a TSE certified POS, and plugin a certified scale (which the Mettler Toledo Arriva S recommend by Odoo is, as a standalone scale), then your total setup may be Ok certification wise in terms of tax and weighing regulations. Your research shows: this is not the case, according to Eichamt, the whole systems needs to be certified together.
  
  From a "common sense"  perspective however (which risk is bigger: the human typing wrong from scale display, or the software grabbing the data wrong), and for smaller customers willing to take the legal risk (customers who may have multiple other non 100% compliant processes in their organisations given their small size and degree of professionalism), using these two "standalone certified components" (Odoo POS and scale) connected might still be an option some customers/Odoo users may chose to go for, having been warned about the legal risks and that the legally safe alternative would be the label printing workaround.
  
  Thank you for this valuable contribution and clarity,
  and joining you in the hope that regulations will be upgraded to 21st century

  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.

  Hi all, 

  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).

• 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!
  
  Best regards,
  Laurence

• 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_cert module, 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.
