Just to clarify, any of the both options "model" or "serial" will work perfect when the devices are not identical.
Using the 4 attributes is a good point but it would add extra complexity to the code for small rewards because I have just checked all my non-serial devices and all of them have the same model.
I'm getting closer to going back to serial
