Home and Away
In the new Philips hue application home and away is a feature for turning your lights on and off either manually or automatically when you leave home. This feature was called Geofencing in the generation 1 hue application.
To use this feature you will need a hue account with your bridge linked to it, follow this link to setup your account if you have not already done this: https://my.meethue.com/en-us/
Once you have selected your rooms, make sure you press Save on the top right and it will return you to the Home & Away menu.
How to Use Home & Away
Now that you have configured what you want home and away to do, there are two different ways to use it.
Manually Change Home & Away
Under the Room, Routines, or More menu you will notice the words Home/Away at the top of the page. If you select the word that is there it will toggle you in between both your Home and Away settings.
Automatically Change using your devices GPS
Under the Home and Away settings there is an option to enable Location Aware. This will use your devices GPS to determine if you are home or not to set your lights.
