To advance real-world applications of non-intrusive load monitoring (NILM), we propose the CMTMU dataset—an innovative dataset that simulates realistic residential power consumption scenarios involving both multiple appliance types and multiple units of the same type. Existing NILM datasets largely overlook such complexity, limiting model generalizability. The CMTMU dataset is constructed by applying an offset-overlay technique to REFIT data, enabling the simulation of concurrent multi-unit appliance usage.
