The 'Sense' device is a smart home monitor that uses impressive sampling technology to recognize the electrical signatures of every electronic device in a consumer's home. With app connectivity, Sense can then present all this data in several different layouts to give consumers an easy to understand breakdown of exactly what's going on with their homes' devices.
The core of the Sense system is the device itself, which looks similar to an internet router. However, rather than connecting wirelessly, the Sense device gets connected via a hard line directly into a home's electrical panel. Sense uses incredibly precise electrical sampling -- "measuring at a million times a second" according to Sense's CEO -- to get a picture of the total power usage in the house. It then uses machine learning to deduce which devices are in use based on its power readings.
