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

  • Weighing scales
    Hey Everyone,

    I'm a fairly new member to the OCA (joined half 2025) and I didn't had much time to catch up.

    I've been in the mailing and I see sometimes questions popping up & people helping eachother, which is great ! 

    At the moment when you want a weighscale for the POS system for odoo EE  a IOT is recommended and a ariva-S model.

    These scales are sometimes too expensive for customers , did anyone else had success with other scales which also work with an IOT box or any other connection.
    Mind you i'm looking for SaaS solutions also, so while i'm open to costume modules for other scales.
    I'm also looking for scales that would work with SaaS enterprise solution.

    Thank you all , and keep up the good work !

    Sincerely
    Kristof
