Help Needed for NILM-based Load Disaggregation of Fans and Mixer Grinders

Hello everyone,

I am a student working on load disaggregation using a data acquisition device sampling Active Power at 1Hz. I have successfully implemented a few deep learning models for this purpose but none of these seem to give any good results with appliances multiple states especially Fans, Mixer Grinders.

Could anyone provide guidance or point me in the right direction on how to tackle this issue?

Thank you in advance for any help you can provide!
