If you’re not going to have 1 at a time or 1 only then the device should stay the same. It usually will only change when there is another plugged in after another. You could do udev rules like your link if you want and then you’d know exactly what the device name would be. It shouldn’t be a problem unless you’re not allowed to write to the hass.io OS. I’ve never named devices like that but it seems pretty straight forward.
