Abstract

This paper presents a health-aware Non-Intrusive Load Monitoring (NILM) system that can both identify household appliance energy usage and detect possible appliance faults using only smart meter data. The proposed framework combines a dual-branch attention-based deep learning model for energy disaggregation with an XGBoost-based anomaly detection model for appliance health monitoring. Experiments on the REFIT dataset show improved performance over existing CNN, LSTM, GRU, DTW, and Random Forest baselines across multiple household appliances.
