What is Non-Intrusive Load Monitoring or energy disaggregation or power signature analysis?
The aim of non-intrusive load monitoring is to obtain a breakdown of the net energy consumption of a building in terms of individual appliance consumption. There has been work on multiple algorithms so as to get this done ( with varying performance) and as always these can be written in any programming language. 
NILMTK itself is written in python and is a good toolkit to describe, analyse and integrate nilm algorithms to compare them.
Does anybody know anything about NILM or power signature analysis? 
Can i do non-intrusive load monitoring using python?
I got to know about one python toolkit known as NILMTK. But I need help for knowing about NILM.
If anybody know about NILM, then please guide me. Thank you.
