Non-Intrusive Load Monitoring Toolkit (nilmtk)

NILMTK: Non-Intrusive Load Monitoring Toolkit

Non-Intrusive Load Monitoring (NILM) is the process of estimating the energy consumed by individual appliances given just a whole-house power meter reading. In other words, it produces an (estimated) itemised energy bill from just a single, whole-house power meter.

NILMTK is a toolkit designed to help researchers evaluate the accuracy of NILM algorithms.

NILMTK is not being actively developed now. However, we believe it does the job it's intended to do! It may take time for the original NILMTK authors to get back to you regarding queries/issues. However, you are more than welcome to propose changes, support!.

Why a toolkit for NILM?

We quote our NILMTK paper explaining the need for a NILM toolkit:

Empirically comparing disaggregation algorithms is currently virtually impossible. This is due to the different data sets used, the lack of reference implementations of these algorithms and the variety of accuracy metrics employed.

What NILMTK provides

To address this challenge, we present the Non-intrusive Load Monitoring Toolkit (NILMTK); an open source toolkit designed specifically to enable the comparison of energy disaggregation algorithms in a reproducible manner. This work is the first research to compare multiple disaggregation approaches across multiple publicly available data sets. NILMTK includes:

• parsers for a range of existing data sets (8 and counting)
• a collection of preprocessing algorithms
• a set of statistics for describing data sets
• a number of reference benchmark disaggregation algorithms
• a common set of accuracy metrics
• and much more!

Please note that NILMTK has evolved a lot since these papers were published! Please use the online docs as a guide to the current API.
