Alexa doesn't open any connection to Amazon servers until you say the hotword 'Alexa'.

  One could still infer from a lack of 'Alexa' hotword prompts over a span of time whether the home was occupied I reckon.

    Or Bluetooth connections if you can use it as a speaker. Or the presence of other devices on the WIFI. There's a few ways you can passively detect human presence, I think.

    That kinda logic doesn't work. Just because someone doesn't use Alexa for hours doesn't mean they aren't home. It happens every night.

      I will elaborate further: inspect usage trends of Alexa to determine anomalies, i.e. times of no usage in the day when the owner isn't home.
