Your smart home can do a lot, but it’s mostly because you activate them. No longer: The Google Home system launches upgrades that allow you to enable features based on whether you are actually present in your home. The system uses the location of an Android phone (provided it is activated) to determine if someone is home or not.
Alternatively, compatible Nest cameras, Nest Tag or the presence detector on the Nest thermostat or Yale lock can turn the system to home or away mode. If any of these methods do not work, you can set the status manually via the Google Home app.
Google suggests pairing the feature with lights that automatically turn off and on when you leave and return. Thermostats can be adjusted to work in more energy efficient ways when no one is at home, turning on or off cameras, etc. The feature is rolling out in stages now, but it may take a week or two to make it available to all users. It will appear at the top of the Google Home app when done.
