It's more like discerning the washing machine based on the power meter, but you know exactly when and how many washing machines turn various bits on and off. Could be doable, with some expensive equipment. For the ghost side channel attacks we did see in situ proofs of concept. It's an open question how many people have the skill to do either those side channel exploits or the power meter washing machine guess above and are also engaged in crime.
