Abstract: Highlights•Two-stage feature selection approach is proposed for the high-dimensionality of IoT data.•A novel WOA-HA algorithm is proposed in the second stage.•WOA-HA has a special chaotic initial solution and adaptive strategy.•The proposed approach outperforms other algorithms on Aalto IoT dataset and RT-IoT 2022 dataset.•The first stage of experimentation with the Aalto dataset resulted in a reduction of the feature set dimensionality by over 50%.
