Re: Connecting weight scales to Odoo

Re: Connecting weight scales to Odoo

Hi Tom,

indeed that is something that is a somewhat ridiclous result of European Regulation. I do agree though:

As long as you break Media, in the sence of

analog -> digital -> paper <-> scan -> digital

the weighing would no longer be conceived "integrated" and the entire thing would be legally compilant.

From a technical standpoint this is odd because

1.) obviously the API of a scale could easily be made "read only", controlled by the internal architecture and thererfore practically immutable

2.) printing something on paper (only to scan it immediatly after) is a waste of natural resources 

But lawyer, politicans and other "high profile" staff needs something to work on and live from as well ;-)

Cheers Frederik

  • Connecting weight scales to Odoo
    Hello,

    I'm looking into connecting weight scales to Odoo, wither for warehouse operations or for quality controls.
    For example, the Mettler-Toledo brand.

    I wonder if we have something under the OCA for this?
    Would PyWebDriver (https://github.com/pywebdriver/pywebdriver) be helpful here?

    Thank you for sharing!

      Yes, our system doesn't require middle things. Just direct websocket connection between browser and weighing scale.

      We also have a talk about this in Jornadas Odoo, although in Spanish (I know Daniel won't have problem with that):

      Hello,

      It's not a Black Box solution. We have changed it to support Epelsa Scales. The code is open, you can see the addons hw_*. If you login to the raspberry pi (it's a default raspbian) you can see that is only a Odoo that launch the hw_* addons. And can be used in a Community Versión, but only in POS. You can use it in Manufacturing.

      Greetings

      Thank you Ignacio and Frederick.

      This is an EE customer and I'm aware that the Odoo IoT box supports Mettler-Toledo scales.
      But it is kind of a black box solution.

      The OCA and open source has spoiled me, and I feel uncomfortable with anything I can't peek inside and hack in case of need :-)
      I was hoping PyWebDriver could provide a drop in replacement for this kind of use case.
      I know it already does for the POS (I used it for an EE customer, because the RaspberryPy did not do well in their work conditions).

      Hello,

      The mettler Toledo can be connected, is in the core o Odoo. You only has to use a iotbox. Some function of iotbox are enterprise, but connect a scale to POS is open source. You can download the raspberry pi image in the Odoo website: https://nightly.odoo.com/master/iotbox/

    • Re: Connecting weight scales to Odoo 
      Well also a solution to do it via Websockets and w/o pywebdriver even. 
So you don't necessarily need a prepared Raspi but just an ordinary 
Linux machine. We did something similar back in the days with a home 
made weighing scale (built from some cheap China hardaware) even. Was 
only for carrier clearance, but worked pretty well on several parallel 
instances. So definitely also worth to look at
