It happens to the best of us: you leave the house, drive away, and realize you left the lights on. With Hue, you don’t need to worry about that anymore: you can set your lights to turn off automatically whenever you leave the house (and turn them on automatically when you return home).
这对我们最好的人来说是偶然的：您离开屋子，开车离开，意识到自己一直开着灯。 有了Hue，您就不必再为此担心了：您可以将灯设置为在离开家时自动关闭(并在回家时自动将其打开)。
Hue does this using a feature called geofencing, which is a fancy term that describes a virtual fence surrounding a specific location. When you enter or leave that fenced-in area, a specific action happens. In this case, your Philips Hue lights can turn on when you enter that virtual fenced-in area, and they can turn off when you leave.
顺化使用名为geofencing的功能进行此操作，这是一个花哨的术语，描述了围绕特定位置的虚拟围栏。 当您进入或离开该围栏区域时，将发生特定操作。 在这种情况下，飞利浦Hue灯在您进入该虚拟围栏区域时可以打开，而在您离开时可以关闭。
Geofencing uses a combination of your phone’s GPS, Wi-Fi, and cellular radio to determine your location. That combination allows your phone to preserve battery more than other GPS-focused apps, making this a decently efficient trick. It isn’t going to drain your battery like, say, a navigation app would.
地理围栏结合使用手机的GPS，Wi-Fi和蜂窝无线电来确定您的位置。 这种组合使您的手机比其他专注于GPS的应用程序可以节省更多电量，这使它成为了一个相当有效的技巧。 它不会像导航应用程序那样消耗您的电量。
To set this up, open the Philips Hue app on your phone and tap on the menu icon in the top-left corner.
要进行此设置，请在手机上打开Philips Hue应用程序，然后点击左上角的菜单图标。
Select “Geofencing”.
选择“地理围栏”。
If “Geofencing” is grayed out, this means the Philips Hue apps doesn’t have permission to use your location, so you’ll need to go into the settings on your iPhone or Android device and give it access.
如果“ Geofencing”显示为灰色，则表明Philips Hue应用无权使用您的位置，因此您需要进入iPhone或Android设备上的设置并授予其访问权限。
Once you’re in, there are two geofencing options to choose from: “Arriving” and “Leaving”, and you can enable both if you want. To have your lights automatically turn off when you leave, select “Leaving”.
进入后，有两个地理围栏选项可供选择：“到达”和“离开”，并且您可以根据需要启用两者。 要在离开时自动关闭灯，请选择“离开”。
Tap on “Lights” at the bottom.
点击底部的“灯”。
Select which lights you want turned off when you leave the house. Tap on “Select all” to select all of them at once. Then tap on the arrow in the top-left corner when done.
选择离开家时要关闭的灯。 点击“全选”一次选择所有。 完成后，点击左上角的箭头。
Tap “Save” in the top-right corner.
点击右上角的“保存”。
If you want to turn your lights on when you return home, the process is very similar. Flip the “Arriving” switch to on, and then tap on “Scene” at the bottom of the next screen.
如果您想在回家时打开灯，则过程非常相似。 翻转“到达”开关，然后在下一个屏幕底部点击“场景”。
Select a scene that will activate when you arrive home.
选择一个将在您回家时**的场景。
Below “Scene”, you can enable “Only after sunset” which will only activate the “Arriving” geofencing feature when it’s dark out. Otherwise, it will be disabled.
在“场景”下方，您可以启用“仅在日落之后”，该功能仅在天黑时才**“到达”地理围栏功能。 否则，它将被禁用。
Tap “Save” in the top-right corner.
点击右上角的“保存”。
Geofencing is now enabled and your lights will automatically turn on and off when you get home and leave, respectively.
现在已启用地理围栏，当您回家和离开时，您的灯光将自动打开和关闭。
Keep in mind that while this won’t use as much battery as a navigation app, it will still drain your phone’s battery quicker than if you had this feature disabled, so you may experience a slight hit on battery life with geofencing enabled.
请记住，虽然此功能不会像导航应用程序那样消耗大量电量，但与禁用此功能相比，它仍会更快地耗尽手机的电池电量，因此启用地理围栏可能会给电池寿命带来轻微影响。
