Energy disaggregation software

I'm writing this post for feedback and help with a current idea I have for a SaaS, all critiques and criticism would be appreciated. I am looking to validate or invalidate my idea for an Energy Disaggregation Software aimed more towards Residential users. I have coded a MVP that takes smart meter data and then currently with very basic algorithms and machine learning from other data will output energy use for Hvac, if specified water heater/Other appliances, base load, ect. I want to know if there is truly a need for this before I go further and if so are you willing to pay for it. General advice would also be helpful, thank you.

TLDR: Would it be helpful to have a software that can take your smart meter energy data and help you optimize your energy use to reduce spending?
