Sensor Residence - gathering data from Smart Homes
Marco Maas shares data based insights from two smart home projects: The "sensor residence" collected various types of data based on movement-, co2- and other sensors, smart speakers and lightbulbs etc. - collected for over 6 months. The technical setup in this setup was quite complex - which was adressed in The "Smart Home Forensic Kit" - which allows raspberry pie users to collect their own data within basically any wifi setup. It helps for example to answer questions like: "Does Alexa listen in all the time?"
