Why not use 4 load cells to weigh the washing machine? If the machine is not empty then consider it is in use.

@pdp11 Thank you for your question. As shown in the brief introduction video, the washing machine is locked and packed in a big box. Only the door and the outer user interface are exposed. Because we would like to design a system with less changes to the current setting. Otherwise, we may design a program for the existing payment system to update the working status of the washing machine.
