I don't use the location stuff on my phone for the Hue app. I try to conserve battery wherever I can. So, the best way for me to have the entry light in my flat go on when I came in or am leaving was a motion detector. I have a switch it is connected to, but it is at the end of the very dark entry hall. So, this detector is perfect for coming home, or when friends show up I know when the door is opened because the light goes on. It was a little too sensitive and would turn on every time I went into the kitchen, so I just created a small deflector to limit the range of the motion detector. I love the convenience.
