S.A.T. words! Disaggregated metering is actually simple in concept. Your utility meter at home measures all the electricity you use.
But it doesn’t tell you which things used how much and when. Disaggregated metering does.
The “disaggregation” technology is pretty cool in theory. It uses computer algorithms to detect different electronic fingerprints associated with different kinds of devices like air conditioners, heaters, refrigerators, washers, dryers, and, to some degree, even lamps and device chargers. It then displays this information via a smartphone app or website. But the device identification can be laborious at first. You should anticipate investing time to help it learn. The outputs you get are a lot of data, which is great, if your goal is a lot of data to analyze…
The most popular disaggregated meters come from Sense ($250-300. Recommended installation by an electrician cost me that much again.) and Bidgely, which only sells through participating utilities.
At this time, we’re recommending disaggregated metering only if you are an energy nerd (like us). But for the rest, the technology is improving. Stay tuned!
