How Home/Away Assist uses your phone’s location

After you grant permission in the Nest app, Home/Away Assist uses your phone’s location to help tell when you’ve left home and when you’ve returned. Instead of constantly tracking your location, the Nest app only receives basic notifications from your phone that say you’re home or away.

Home/Away Assist uses your Nest products’ activity sensors to tell when you’ve left home and when you’ve returned. But since you probably keep your phone (or tablet) with you throughout the day, Nest can also use its location to help Home/Away Assist more precisely tell when you’ve actually left home and when you’ve come back.

With Home/Away Assist you don’t have to manually switch all your Nest products on or off, or rely on a set schedule. For instance, when you leave your home, Home/Away Assist can turn down your heating to save energy and turn on your Nest camera streaming to keep an eye on things.

How to use your phone's location and get the best experience from Home/Away Assist

When you sign up for a free account in the Nest app, you’ll be asked if you want to use your phone or tablet to help with Home/Away Assist. You can only choose one device. So if you have more than one (like a phone and a tablet, or work and personal phones) you should pick the one you take with you most often.

Once you’ve set up Home/Away Assist to use your phone’s location, it will use a combination of cellular and Wi-Fi data from your phone to help tell if you’ve left or you’re back home. The Nest app uses the standard location services built into iOS and Android. These services use a combination of cell tower signal strength, Wi-Fi network information, and occasionally GPS to narrow down your location if needed.

So to help ensure the best experience with Home/Away Assist, you should at least have mobile or cellular data, and Wi-Fi enabled in your phone’s settings.The Nest app will help you with this by automatically running a Health Check when you open the app, and let you know whenever changes to your phone’s settings may affect Home/Away Assist accuracy.

How Home/Away Assist uses GPS data

Having GPS on can help if your cell and Wi-Fi connections are weak. The Nest app will only rarely check GPS location if your cell and Wi-Fi connections have been lost, and your phone hasn’t checked in in the past couple of days. Limiting its use to rare occasions minimizes the impact it will have on your phone’s battery charge.

The Nest app doesn’t continually record your phone’s exact location like a GPS navigation app for driving. It doesn’t need to. Home/Away Assist only needs to know two things: whether you’ve left or come back. To do this, the app defines a large area around your home that acts like a home zone. Your phone isn’t used to determine when exactly you walk in the door or when you drive out of the garage. The Nest app only gets a notification from the location services of your phone’s OS to determine when you enter or leave your home zone. So for instance, if you walk over to your next door neighbor’s house, your home may not switch to away.

How other people's phones are used

Home/Away Assist can use other people’s phones in exactly the same way as it does yours. Anyone who has access to a Nest home with an account in the app can use their phone’s location to help the home know if someone is there, or if everyone is gone. People who have phones that help control your home won’t be able to see exactly who’s home or who’s away, just that someone is home or everyone is gone.
