Hi Lorenzo, I have seen this “balance de ruche (balance apicole) Beescale4 (BS4)” also some month ago as you shared the link on The Beescale4 (BS4) by Jérôme Alphonse and I wonder what kind of sensors this are. i do not thinkt this are bathroom load sensors but a kind of weight or force sensitive mat. But I don’t know. So when you have contact to the designer and they are willing to share some details it would be nice they can give some information about the sensor.
