"I wouldn't be surprised if an Echo placed in a bedroom detects every time a couple (or more) has sex."
An article somewhere recently was about a guy's house that he had wired with all sorts of detectors and monitors. The idea was to see where he could save energy and water. One detector was for CO2. A surprise result was that it indicated a rise when people were having fun in a bedroom.
