+
+Prerequisite
+------------
+
+Connecting a scale requires the use of an **IoT System**.

+
+Configuration
+-------------
+
+Scale connection
+~~~~~~~~~~~~~~~~
+
+#. :ref:`Access the POS settings <configuration/settings>` and select the POS, or click the
+   :icon:`fa-ellipsis-v` (:guilabel:`vertical ellipsis`) icon on a POS card and click
+   :guilabel:`Edit`.
+#. Scroll down to the :guilabel:`Connected Devices` section and enable :guilabel:`IoT Box`.
+#. Select the scale in the :guilabel:`Electronic Scale` field.
+#. Click :guilabel:`Save`.
+
+Product configuration
+~~~~~~~~~~~~~~~~~~~~~
+
+#. Go to :menuselection:`Inventory --> Configuration --> Settings`.
+#. Scroll down to the :guilabel:`Products` section and activate :guilabel:`Units of Measure`.
+#. Go to :menuselection:`Point of Sale --> Products --> Products`.
+#. Select a product to weigh.
+#. Ensure the :guilabel:`Point of Sale` checkbox is activated for the product to be available in
+   POS.
+#. Go to the :guilabel:`Point of Sale` tab and activate :guilabel:`To Weigh With Scale`. This
+   enables the product to be weighed directly on the connected scale at the POS.
+#. Return to the :guilabel:`General Information` tab and set a :guilabel:`Sales Price` per
+   :guilabel:`kg`.
+
+.. important::
+   The selected unit of measure for weighable products must be :guilabel:`kg` to ensure compliance
+   with **European regulations**.
+
+.. seealso::
+   :doc:`../../inventory_and_mrp/inventory/product_management/configure/uom`
+
+European regulations
+--------------------
+
+As scales used in commercial transactions are certified, Odoo must adhere to specific European
+requirements. If the database does not meet these European regulations, a distinct
+:icon:`fa-balance-scale` (:guilabel:`red scale`) icon displays prominently in red.
+
+Click this red icon opens to modal window that explains the reasons for non-compliance. To
+automatically implement the necessary changes to the Odoo settings and achieve compliance, click
+:guilabel:`Apply changes`. Once the database meets regulatory requirements, the
+:icon:`fa-balance-scale` (:guilabel:`scale`) icon turns green, indicating full compliance.

+
+Additional guidelines
+~~~~~~~~~~~~~~~~~~~~~
+
+:doc:`The customer display <shop/customer_display>` and POS display must each be at least 6 inches.
+However, we recommend using a larger screen for better end-user readability.
+
+Usage guideline
+---------------
+
+#. :ref:`Open a POS session <pos/session-start>`.
+#. Select the product to weigh on the POS interface or scan its barcode, which opens a modal window.
+#. Place the product on the scale and wait for the weight to be displayed.
+#. Once the weight is determined, the price is automatically computed.
+#. Click :guilabel:`Order` :icon:`fa-angle-double-right` to add the product to the cart.
+#. Remove the previous product to weigh a second item.

+   :scale: 85 %
+
+.. important::
+   Make sure the scale returns to `zero` before weighing a new product. If it does not, the
+   :guilabel:`Order` :icon:`fa-angle-double-right` button remains unclickable until it is reset.
