I bring my bowl of soup over to the microwave, but to open the door, I need a free hand, and I don't want to spill the soup, so I put the bowl down on the microwave, open the door, put the bowl inside the microwave, close the door, and the microwave tells me it doesn't weigh anything.

I think the points where the internals are mounted to the case might be the best place to measure, although any of these clever measurement locations depends on having a connection that's both secure and measures pressure.

All it has to do is measure the absolute difference between the last two steady-state weights. That's not computationally demanding; my bathroom scales (the non-internet-connected red-LED-digits variety) can do it.
