Could you build this?
Partial The Home Assistant integration scaffolding and sensor entities are routine, but estimating per-appliance power from a whole-home signal is a non-intrinsic load monitoring (NILM) research problem that needs real algorithms and labeled data.
What it would actually take: Build the HA custom integration in Python with an event-driven sensor pipeline and a configuration UI. The core is a NILM model: event detection on the aggregate signal, followed by appliance signature matching or a learned disaggregator. Making it accurate across homes requires signal-processing expertise and labeled multi-appliance energy datasets for training and validation.
