      Once the code is developed, it would be great if there was a physical way to prevent firmware rewriting (such a fuse to blow or a wire to cut)

          In my opinion, do a hardware fuse is not a good idea, because updating the programm would not be possible anymore.
          But to have a password protection would be good.

          Becuase when the devices are spread or installed. People could overwrite the firmware or the development using the uiflow webapplication, they just need to know the API number and thats easy to find when booting up and changing the menu.

          if on Uiflow you must enter a password, this would also help to protect from overwriting the programm but you would be able to install an update.
