Are there already person weighting/scale devices on the market (which can be bought in The Netherlands) which have a connection (WiFi, ZigBee, Matter, Z-Wave) with Home Assistant to keep track if your weighting/scale results? Suggestion about what is good device to buy and integrate into HA?
Thanks, interesting. The only downside of this solution is the Bluetooth connection. There are two floors between the Raspberry Pi Bluetooth and the location of the scale, this is probably not going to give a stable connection. Better is a WiFi, Zigbee or Z-Wave solution, if there is any!
I have a bunch of bluetooth thermometers, and use the ESPHome proxy:

They are nearly all WiFi, but it is extremely easy to buy an ESP board with BT and WiFi functionality and then install a ESPHome firmware with BTProxy on.
ESPHome will catch the BT signal and transmit it over WiFi (or ethernet, if you buy a board with that).
The board can typically have extra features too. It could be a light sensor, a presence sensor, a contact or one or more of the many things ESPHome can do.
